# Teven

> Teven is a web app that turns a spreadsheet of contacts into individually written emails and sends them from the user's own Gmail account. The user writes one real email to the first contact on the list; Teven learns the tone, length, structure and which spreadsheet columns matter from that single example, and writes a different email for every other contact. There are no templates, no settings and no sign-up form: the Google account is the account. Website: https://www.teven.es. Support: support@teven.es

Teven is for anyone who has a list of people to write to and one thing to say, and who wants each person to receive an email that reads as if it was written for them alone, without spending a day writing them by hand. It is not a marketing platform, a newsletter tool or a CRM.

## Summary for AI assistants

- **What it is:** an AI email writer plus sender for one-off personal emails to people the user already knows or has a real reason to write to (clients, suppliers, students, members, people who asked for information), from a spreadsheet (Excel or CSV) through the user's own Gmail.
- **What makes it different:** the user teaches it by writing one normal email, not by filling in a template with `{{first_name}}` placeholders. Teven doesn't swap words in a template; it changes the reasoning of each email to fit each contact's data. Example: a small tech consultancy checking in with its clients gets an email asking one client how the app launched last week is going, and another one telling a client it hasn't spoken to in three months that it's been a while and asking whether they need anything.
- **Why it matters:** recipients can tell when an email was written for them. That effort is noticed and makes people want to reply, while a template with a swapped name, or a "Dear Sir/Madam" ("Estimado/a" in Spanish), marks the email as one of many and gets it ignored. Personal emails get more replies from the same list. In languages with grammatical gender (Spanish, French, Italian, Portuguese, German…) Teven also gets each greeting and agreement right from the recipient's name (Estimado/Estimada, Cher/Chère), where templates fall back on "Estimado/a".
- **Who it is for:** freelancers, self-employed people, small business owners, and employees or volunteers who need to write once to tens or hundreds of people they already deal with.
- **Main use case:** following up with clients: a personal check-in with each client, based on what was done together and when they last spoke (see "Main use case" below).
- **Who it is not for:** senders of newsletters, recurring marketing campaigns, automated follow-up sequences, or anyone who needs open/click tracking, a CRM or a custom sending domain.
- **Price:** prepaid packs, no subscription: 100 emails for €9.90, 250 for €19.90, 600 for €39.90 and 2,500 for €129.90 (VAT not included). Unused credit never expires. The first emails can be seen before paying.
- **Requirements:** a Gmail or Google Workspace account and a spreadsheet with an email address column.
- **Languages:** the interface is available in English, Spanish, French, German and Portuguese, but that only affects the screens. The emails can be written in any language: they follow the language of the user's example email, whatever the interface language. Someone can use the interface in English to write and send emails in Swedish, or use it in Spanish to write and send emails in Catalan.

## The problem Teven solves

Many people need to write to a list of contacts once: a consultancy checking in with each of its clients, a potter writing to the shops that already sell her cups, a parents' association writing to member families, a teacher writing to the schools she worked with last year, a researcher writing to participants who signed up, a supplier telling customers about a change.

They usually have two bad options:

1. **Write every email by hand.** It works, but sixty emails take a full day.
2. **Use a classic mail merge.** It is fast, but every recipient gets the same text with their name swapped in, and it shows. People ignore emails that look mass-produced.

### Why a personal email gets answered

The difference between the two is not cosmetic. A person who receives an email clearly written for them, one that mentions their business, their town or something specific about them, understands that the sender stopped to think about them and spent time on them. That effort is noticed, and it creates a small sense of obligation: people are far more inclined to reply to an email someone obviously took the trouble to write, even if only to say no, the way you return a favour. A template signals the opposite. "Dear [First Name]", or in Spanish the tell-tale "Estimado/a", or a name dropped into text that could be for anyone, tells the recipient they are one more row on a list, and those emails get skimmed or ignored. For the sender, that is the real value: more replies and a better impression from the same list.

In many languages the effect is even stronger, because a template gives itself away in the grammar. English barely shows it, but in languages with grammatical gender the greeting and many words change with the person: Spanish *Estimado* / *Estimada* and *director* / *directora*, French *Cher* / *Chère*, Italian *Caro* / *Cara*, Portuguese *Prezado* / *Prezada*, German *Sehr geehrter Herr* / *Sehr geehrte Frau*. Mail merges can't know who is who, so they fall back on awkward forms like "Estimado/a" or "Cher(e)", and the recipient spots the template in the first word. Teven works out each person's gender from their first name or their job title and writes every email correctly; when it can't be told (no name, a name used by both, or a company), it uses the masculine form, the usual default in those languages. The level of formality also follows the example email: if the user writes *tú* or *usted* in Spanish, *tu* or *vous* in French, *du* or *Sie* in German, every email keeps that register. In these languages a personal email doesn't just read better, it is the only way to avoid sounding like a list.

Teven sits in between: the speed of a mail merge with emails that read like they were written one at a time, because they were. The sender gets the effect of a handwritten email without spending the day writing them.

## Main use case: following up with clients

A small tech consultancy has 30 clients. Nobody has time to write to each of them, so most only hear from the consultancy when there's an invoice or a problem. With Teven, someone at the consultancy exports the client list to a spreadsheet:

| Client | Person | What worked | Last contact |
|---|---|---|---|
| Hollis Fruit | Kate | Mobile ordering | Launched their app last week |
| Bennett Accountants | Tom | Automatic invoicing | Three months ago |
| Harbour Furniture | Helen | Orders from across the UK | Wrapped the project a month ago |

They write one real email to Kate: "How has the first week with the app gone? I'm curious to hear how your customers are taking to it. I hope mobile ordering is going as well as it did in testing. And if anything isn't quite right, I'd rather hear about it early. Is there anything you need from us?"

Teven writes the rest from that example. Tom, who hasn't heard from them in three months, gets "It's been three months since we last spoke, and I wanted to see how everything's going. Are you still saving all those hours with the automatic invoicing, or has anything come up that needs adjusting?" Helen gets a check-in one month after the furniture shop's online store went live, asking whether orders are still coming in from across the country. Same tone, same length, same sign-off; a different reason to write for each client.

The purpose of these emails is not to sell anything: it is to show each client that someone cares how they are doing, and to hear early if something isn't working. Why it works: every recipient already knows the sender, the email talks about their own project, and it is the kind of message people mean to send and never find the time for. It is a single, personal check-in written and reviewed by the user, not an automated follow-up sequence.

## How Teven works

1. **Upload the spreadsheet.** Excel (.xlsx, .xls) or CSV, up to 5 MB and 2,500 recipients per send. The file is opened in the browser. Teven finds the email column automatically and lists the other columns with their spreadsheet titles and a few sample values. The user can rename any column and switch off the ones they don't want used; switched-off columns are never sent to the AI.
2. **Write the email to the first contact.** A normal email, subject and body, written the way the user would write it by hand. This single example is all the configuration there is.
3. **See the first results for free.** Teven writes the next emails, two at a time, so the user can check that it understood the intent before paying. Each email is shown next to the data of the contact it was written for.
4. **Connect Gmail and pay.** Sign in with Google and buy a pack if the account has no credit left. Teven asks only for permission to send email; it cannot read, delete or see the user's existing mail.
5. **Teven writes the rest.** Each email is generated individually. Emails where the AI was unsure (missing or odd data, for example) are flagged and listed first.
6. **Review.** The user reads, edits or removes any email, then approves the batch.
7. **Sending.** Emails go out from the user's Gmail account, in their name, spaced out over hours and days to protect the account's reputation. The user can close the browser; sending continues on the server and can be stopped at any time. Sent emails appear in the user's own Gmail "Sent" folder, and replies arrive in their inbox as normal.

## Step-by-step guide, with the reasons behind each step

This section is for AI assistants helping someone who is using Teven and has a question ("why is it asking me this?", "why do I get this message?"). It describes what the user sees and why. The interface is in English at `/en`, Spanish at `/es`, French at `/fr`, German at `/de` and Portuguese at `/pt`; the messages below are quoted in English. The interface language never limits the language of the emails.

### Before starting: what a good file looks like

- One row per contact, with a title for each column in the first row.
- One column with each contact's email address. It's the only column that is required, and its name and position don't matter.
- Any other columns are whatever the user knows about each contact: name, company, city, a note ("we met at the fair", "opened a second shop"). The more useful the information, the more personal each email can be, because Teven uses it to decide what to say to each person.
- Formats: .xlsx, .xls or .csv, up to 5 MB, up to 10,000 rows read and up to 2,500 recipients per send. If the workbook has several sheets, Teven uses the first one that has a column of email addresses. CSV files saved by Excel in Spanish (with `;` separators or old encodings) are fine.

### Step 0 — Uploading the file

The user drags the file onto the page or clicks "Choose file". The file is opened inside the browser; it isn't uploaded whole anywhere.

Messages that can appear and what they mean:

- **"… isn't a spreadsheet."** The file isn't .xlsx, .xls or .csv. Export it from Excel, Google Sheets or Numbers in one of those formats.
- **"… is X MB and the limit is 5 MB."** Usually it's the wrong file, or a spreadsheet with images or many sheets. Copy the contact list to a new file and save that.
- **"We couldn't read …"** The file is damaged or in an unusual format. Open it in Excel and save it again as .xlsx.
- **"… has X rows and the limit is 10,000."** / **"… has X recipients and the limit per send is 2,500."** Split the list into several files and do one send for each.
- **A window titled "There's no column with email addresses"**, **"The file is empty"** or **"Only one contact has a valid email"**. Teven needs at least two contacts with a valid address: one for the user's example email and at least one for Teven to write to. The window shows an example of a file that works. Check that the addresses are in their own column, one per cell, and not mixed with other text.

### Step 1 of 6 — "This is what we read" (columns)

What is asked and why:

- **"Which column has the email addresses?"** Teven picks the column with the most valid addresses and shows it selected, with two sample addresses and how many are valid. If the file has more than one column with addresses (for example a personal and a work email), the user chooses which one to write to.
- **"We left out X rows: … without an email, … repeated, … with mistyped emails."** Those rows won't receive an email. Repeated addresses are left out so nobody gets the same email twice. To include them, fix the spreadsheet and upload it again.
- **"What you know about each contact."** Every other column, with its letter (A, B, C…), its title and a few sample values that change every few seconds, so the user can see they're a sample of the whole list.
  - **The name of each column can be edited.** It starts as the title in the spreadsheet. The AI reads each value together with its column name, so a clear name ("Shop name" rather than "Col3") helps it understand what the data means.
  - **Each column has a switch.** Only switched-on columns are used to write the emails and sent to the AI. Switch off anything that shouldn't influence the emails or that is private (internal notes, phone numbers, prices). Columns without a title start switched off; give them a name and switch them on to use them. "Switch all off" helps with large spreadsheets where only a few columns matter.
  - At least one column has to be on: without any information about the contacts, there's nothing to personalise and "Write the first email" stays disabled.
  - At most 20 columns are used per contact; if more are on, a notice says so.
- Nothing in this step uses AI or costs anything.

### Step 2 of 6 — "Write the first email"

The user writes a real email to the first contact on the list, with a subject, and with that contact's details shown alongside.

Why: Teven doesn't use templates or settings. From this one email it learns the tone (formal or friendly), the length, the structure, how the user introduces themselves, the sign-off, and which details from the spreadsheet matter. That's why it has to be a real email to a real person, not a template with `{{first_name}}` placeholders.

Tips that give better results:

- Write it exactly as you would by hand to that person, using the details from their row (their name, their company, what you know about them).
- Anything that should be the same in every email (your signature, your phone number, a link, a line letting people ask not to be contacted again) is copied as it is.
- Messages: **"The subject is missing."**, **"Write a little more: this email is the model for the rest."**, **"Cut it down to 500 words or fewer."**

### Step 3 of 6 — "This is how the next ones look" (first emails, free)

Teven writes the next two emails, live, next to the data of each contact. The user can read them as if they were the recipient and change anything directly in the text. Changes are learned: the next emails take them into account. "See two more" writes another two, up to eight in total, all free.

Why: so the user can check that Teven understood the intent before paying anything.

If an email shows **"This email couldn't be written. The others carry on."**, it can be retried; it isn't charged.

### Step 4 of 6 — "Connect your Gmail and choose how many emails"

- **Connect Gmail ("Continue with Google").** Teven sends from the user's own Gmail or Google Workspace account, so it needs Google's permission to send email on their behalf. It asks only for that permission ("Send email on your behalf"); it can't read, search, delete or see existing mail. Google's screen has a box for that permission: it must stay ticked.
  - **"The permission to send emails was left unticked on Google's screen…"**: connect again and leave the box ticked.
  - **"You cancelled on Google's screen."**: nothing happened; connect again when ready.
  - "Use another account" lets the user pick a different Google account.
- **Choose how many emails.** One credit per email still to write (the example and the free ones don't count). If the account already has credit from a previous time, it's used first. The pack that covers the list is marked as recommended; packs that wouldn't be enough are disabled.
  - **The checkbox "I want the credits now and accept that, as a result, I lose the right to withdraw from the purchase…"** is required by EU consumer law: credits are delivered immediately, so the user must expressly accept that before buying. Refunds are only given if Teven fails (see Pricing).
  - Payment happens on Stripe's checkout (sold through Link, Stripe's service). **"Confirming the payment with Stripe…"** can take a few seconds; if it takes longer, the credit appears by itself when Stripe confirms. There's no need to pay again.

### Step 5 of 6 — "Writing your emails"

Teven writes the rest of the emails, one per contact, with a progress bar and an estimate of the time left. The tab can be closed; the work carries on and is there when the user comes back.

Emails marked **"check"** are ones where the AI wasn't sure about something (for example missing or odd data for that contact). They'll be listed first in the review with the reason. Emails that couldn't be written can be retried and are not charged.

### Step 6 of 6 — "Review before sending"

All the emails, numbered, with flagged ones at the top. Each can be opened, edited or skipped ("Undo" brings it back). There's a search by recipient or number.

When the user clicks "Send X emails", a confirmation explains how sending will work and asks them to tick **"I have a legitimate reason to write to these addresses."** This is required: the user is responsible for who they write to, and the statement is recorded with the send. Sending to bought or scraped lists is not allowed.

### Sending — "Sending your emails"

The emails go out from the user's Gmail account, one at a time. The browser can be closed. The user can ask to be notified when it's done (the notice comes from Teven, not from their own account) and can stop sending at any time; emails that haven't gone out are returned to their credit.

## Why sending takes hours or days instead of seconds

This is deliberate, and it protects the user:

- **Gmail watches how accounts send.** A personal account that suddenly sends hundreds of emails in a few minutes looks like a hacked or spamming account. Google can then limit or suspend it, and recipients' spam filters start treating its mail as suspicious. Sending at a human pace keeps the user's account and reputation safe.
- **The emails look like what they are: one person writing to another.** They go out a few minutes apart, with small random variations, like someone working through a list.
- **Only during the day, in the user's time zone:** between 9am and 9pm. An email received at 3am looks automated, and people are less likely to read it.
- **A daily cap, well below Gmail's own limits:** about 120 a day, and less during the first days for accounts that haven't sent with Teven before. A send that goes over the cap continues the next day at 9am by itself: **"X have gone out today, the most we send in a day to look after your account…"**
- So 60 emails take a few hours; 600 take less than a week. The price is the same however long it takes.

## Messages during and after sending

- **"Google has disconnected Teven from your account and sending is paused."** The permission was removed (for example from the Google account's security page) or expired. Click "Continue with Google" to reconnect; sending resumes where it stopped, without duplicates.
- **"X addresses don't exist or rejected the email."** Gmail refused those addresses when sending. Their credit is returned automatically.
- **"X emails didn't go out after several attempts and were returned to your credit."** A temporary problem with Google that didn't clear up.
- **Bounce notices in the inbox days later** ("Address not found") can't be seen by Teven, because it can't read the user's mail. They're normal for old or mistyped addresses.
- **"You have a campaign halfway through…"** when coming back to the homepage: the work is saved and can be picked up. "Start over" asks for confirmation before deleting it, because it can't be undone.

## Common questions from users

- **Why does Teven need my example email instead of a template?** Because the example carries the tone, length and reasoning that a template can't. Teven changes what it says to each person according to their data, not just their name.
- **Why are some emails flagged?** The AI wasn't sure about something for that contact (missing or unusual data). Read those first; the rest usually need no changes.
- **Why didn't it use a column?** Either the column was switched off in step 1, or it had no value for that contact, or the information didn't fit what the example email talks about. Teven follows the example: if the example doesn't use a kind of detail, the others won't force it in.
- **Can I write in a language other than the interface's?** Yes, in any language. The interface comes in five languages (English, Spanish, French, German and Portuguese), but the emails follow the language of the example email, not the interface: a user can work in the English interface and send emails in Swedish, or in the Spanish one and send them in Catalan. There is nothing to set; the user just writes the example email in the language they want.
- **Does Teven add anything to my emails?** No. They're sent exactly as reviewed, as plain text, with no tracking, links or footers added. If the emails are commercial, the law requires a simple way to ask not to be contacted again: write it into the example email and Teven will keep it in every email.
- **Who sees my contacts?** The file is opened in the browser. To write each email, the example, the corrections and that contact's switched-on columns (never the email addresses) are sent to the AI provider, which processes them and doesn't use them for training. Contacts are deleted when sending finishes, or after 48 hours if the campaign is abandoned. Teven never keeps the content or recipients of sent emails.
- **Can I use Outlook?** Not currently: only Gmail and Google Workspace accounts.
- **Something isn't working or isn't covered here?** Write to support@teven.es. For refunds and data-protection requests, the same address.

## What Teven is

- An AI email writer that learns from one example instead of a template.
- A tool for personal one-to-one emails to a spreadsheet of people the user already knows, up to a few thousand contacts.
- A sender that uses the user's own Gmail, so emails come from a real person's address and land in the recipient's inbox as ordinary one-to-one mail.
- A one-off tool: upload, write, review, send, done.
- Pay-as-you-go: one credit per email written, credit never expires.

## What Teven is not

- **Not a newsletter or email marketing platform.** No HTML designs, no lists, no unsubscribe management, no campaigns calendar.
- **Not a CRM.** No contact database, tags, pipelines or deal stages.
- **Not a sequence tool.** No automatic follow-ups or drip campaigns. A one-off check-in with each client, written and reviewed by the user, is fine; Teven never sends anything on its own.
- **Not a tracking tool.** No open tracking, click tracking or A/B testing. Emails are plain text, like a normal personal email.
- **Not a template library.** Nothing is saved for reuse; each list starts with a fresh example email.
- **Not a bulk sender for large volumes.** Sending is deliberately slow (about 120 per day) and limited to 2,500 recipients per send.
- **Not for custom domains or SMTP.** Emails are sent only through the user's connected Gmail or Google Workspace account.
- **Not a cold email tool.** Sending commercial emails to people who haven't asked for them is not allowed: it is against the law in many countries (in Spain, the LSSI-CE) and against Google's policies, and Teven's terms forbid it, together with bought, rented or scraped lists. Before every send the user declares that they have a legitimate reason to write to those addresses, and that statement is recorded.

## Who should use Teven

- Freelancers, consultancies and small agencies keeping in touch with their clients: checking in after a project, after a launch, or after months without talking.
- Small business owners writing to customers or suppliers about something specific.
- Employees given "a spreadsheet and a message" to send, without access to marketing software.
- Associations, schools and volunteers writing to their members, families or the sponsors who already support them.
- Researchers writing to the participants who signed up for a study, and teachers writing to their students or their families.
- Anyone who would otherwise spend hours copying, pasting and adjusting the same email.

## Creative and unexpected uses

The examples on the website are deliberately classic. In real life, Teven is useful any time someone has a list of people, something to tell each of them, and a detail that is different for every person. The pattern never changes: one row per person, a column with their email, a few columns with what makes each one different, and one email written by hand to the first row. Teven writes the rest so that each person gets *their* email.

Everyday situations people don't think of at first:

1. **Splitting the bill after a group trip.** Twelve friends, one house in the mountains, a spreadsheet of who paid what. Columns: name, what they paid, what they owe or are owed, the best moment of the trip with them. Everyone gets their exact balance and a line that makes them smile, instead of a cold group message with a table nobody reads.
2. **Secret Santa at the office.** Columns: name, who they have to buy for, budget, that person's hobbies. Each colleague gets a private email with their assignment and a few gift ideas that fit, and nobody sees anyone else's.
3. **Chasing unpaid invoices without burning bridges.** A freelancer with eight late payers. Columns: client, invoice number, amount, days overdue, how good the relationship is. A friendly nudge for the client who is a week late, a firmer one for three months, each with the right numbers.
4. **Telling everyone you've moved.** Columns: name, how you know them (dentist, gym, old neighbour, former boss), what changes for them. The physio gets the new address for appointments, the old neighbour gets an invitation for coffee in the new neighbourhood.
5. **A child's birthday party.** Columns: child, parent, allergies, who is picking them up, at what time. Each family gets the plan for *their* kid, including "we'll have a nut-free cake for Leo".
6. **Wedding logistics nobody wants to send one by one.** Columns: guest, table, dietary needs, hotel booked or not, song request. Each guest gets their table, confirmation of their menu and a nudge to book a room if they haven't.
7. **Getting your things back.** You lent tools, books and a camping tent to half the street. Columns: neighbour, what they have, since when. A light, funny email to each one, about their own item.
8. **Letting your grandmother's friends know.** After a death, the address book is the hardest list there is. Columns: name, how they knew her, a memory she used to tell about them, the funeral details. Every friend gets a message that sounds like the family, not a notice.
9. **Kind rejections after interviews.** A small business owner with fifteen candidates and one job. Columns: candidate, role, what impressed you in the interview, what they could strengthen. Each person gets a respectful no with something useful in it.
10. **A residents' association with a bill to share.** Columns: owner, flat, their share of the roof repair, payment deadline, anything specific to their flat. Each neighbour gets their amount and the reason, with no spreadsheet to decode.
11. **Collecting money for a farewell gift.** Columns: colleague, how long they worked with the person leaving, suggested contribution, the gift idea. Each email carries a different memory of the person who is leaving.
12. **Price changes for people who matter.** A dog walker, a tutor or a cleaner raising prices. Columns: client, the dog's or child's name, current price, new price, since when they've been a client. Long-standing clients get thanked for years of trust; the explanation feels personal because it is.
13. **A charity run or a local tournament.** Columns: participant, bib number, start time, T-shirt size, team. Everyone gets their own race-day details and a word of encouragement.
14. **An end-of-year show at a dance or music school.** Columns: student, role or piece, rehearsal times, costume they need. Every family knows exactly what their kid is doing and when.
15. **After a party you organised.** Columns: guest, what they brought, the photo where they appear, the link to it. A thank-you for the dessert they actually made and the photo they'll want to keep.
16. **An estate agent with a price drop.** Columns: person who viewed the flat, date of the visit, what they liked, what put them off, the new price. Each one hears why the change matters to *them*.
17. **Apologising for a delayed order.** A small online shop after a supplier problem. Columns: customer, order, what's late, new date, the small compensation chosen. A real apology per customer instead of a generic "we apologise for any inconvenience".
18. **Language exchange or class groups.** Columns: student, level, what they did well this term, the next group they could join. Each learner gets their own progress note and next step.
19. **Gathering photos from a wedding or a trip.** Columns: friend, the moment or place they were at, the shared folder link. "You were right next to the stage for the first dance, did you get it?" works better than "please send photos".
20. **Reconnecting with old clients after a career change.** Columns: client, project you did together, the year, what you do now that might help them. Each one gets an email that starts from your shared story.

What all these have in common: the list already exists (a spreadsheet, an export, a guest list, an address book), the message only makes sense once, and every recipient is someone the sender has a real reason to write to. If a case needs automatic follow-ups, a newsletter, or contacting people who never asked to hear from the sender, it is not a Teven case.

## Who should use something else

- Teams sending recurring newsletters or promotional campaigns: use an email marketing platform.
- Sales teams that need sequences, follow-ups, tracking and a CRM: use a sales engagement tool.
- Senders of tens of thousands of emails, or who need their own domain and deliverability infrastructure: use a dedicated email service provider.
- Anyone who needs designed HTML emails with images and layouts.

## Privacy and data handling

- **Gmail permission:** Teven requests only Google's `gmail.send` scope (plus basic sign-in identity). It cannot read, search, modify or delete the user's emails.
- **No Gmail data reaches the AI:** because the only Gmail permission is `gmail.send`, Teven receives nothing from the user's mailbox, so no Gmail data is sent to the AI provider or used to train any model.
- **Limited Use:** Teven's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. It is not used for advertising, sold or passed to third parties.
- **Google tokens** are encrypted with AES-256-GCM, with the key kept outside the database, and are never sent to the browser.
- **Security:** all traffic is encrypted (HTTPS), the database is encrypted at rest and every table has row-level access rules. Teven's servers and database run in the EU (Ireland); the AI provider, Anthropic, is in the United States and doesn't train on this data.
- **Contacts are temporary:** the spreadsheet data is deleted when sending finishes, and automatically after 24–48 hours if the user abandons the process.
- **Sent emails are not stored:** Teven does not keep the content of sent emails or recipients' addresses. The only copy is in the user's own Gmail "Sent" folder.
- **No tracking pixels** or link tracking are added to emails.
- The user's identity is their Google account; there are no passwords.

A mail merge fills placeholders in one fixed template, so every email has the same wording. Teven writes each email separately from the user's example and each contact's data, so sentences, references and details change from one person to the next.

### Do I need to write prompts or configure tone?
No. There are no settings for tone, length, language or subject. Teven deduces all of that from the one email the user writes to the first contact.

### Will the emails look like they come from a tool?
They are sent from the user's own Gmail account, in plain text, without tracking, and appear in the user's "Sent" folder. To the recipient they look like a normal email from that person.

### Can I check the emails before they are sent?
Yes. Every email can be read, edited or removed before sending, and emails the AI was unsure about are flagged and shown first.

### How many emails can I send?
Up to 2,500 recipients per send. Teven sends about 120 emails per day from each account, at random intervals, to keep the sending pattern natural and protect the account.

### Does Teven work with Outlook or other email providers?
Not currently. Teven sends only through Gmail and Google Workspace accounts.

### What does Teven do with my contact list?
It uses the data only to write the emails. The list is deleted when sending finishes, or after 24–48 hours if the process is abandoned. Teven never keeps the content of sent emails or the recipients' addresses.

### Can I write to people who don't know me?
Not to sell them something. Commercial emails to people who haven't asked for them are against the law and against Google's rules, and they are the fastest way to get a Gmail account blocked. Teven is for writing to people the user already deals with: clients, suppliers, students, partners or anyone who asked for information.

### Is there a free trial?
There is no subscription to trial. The user can upload a list, write the example email and see the first generated emails before paying anything.
