21:12What Batmail is

An AI email assistant for Gmail.

Batmail works the Gmail accounts you connect while you sleep, then hands the morning back to you with one short brief. Here is exactly what that means.

What it does

Batmail checks the new mail that arrives in the Gmail accounts you connect, matches each message against rules you write in plain English, and then archives, labels, stars, or forwards it. Every morning it delivers one roundup: what it handled overnight, and the few emails still waiting on you.

What it asks of your Google Account

You connect each mailbox through Google sign-in and grant one Gmail permission, gmail.modify. That is what lets Batmail read incoming mail, apply labels, archive, and star, and send only the replies or forwards your own rules ask for. Nothing outside the mailboxes you connect is ever touched.

What you stay in control of

You write the rules, so you decide what gets handled and what is left alone. Every action is logged with the reason behind it, most can be undone in one click, and disconnecting a mailbox revokes and deletes its token on the spot.

What it never does

Your mail is never sold, never used for advertising, and never used to train AI models. Batmail sends nothing on its own initiative: a reply or a forward happens only when a rule you wrote says so.

Batmail's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements. The full detail is in our privacy policy and terms of service. Questions go to support@batmail.ai. Batmail is built and operated by Momentum Labs.

21:47Before you sleep

Set it up tonight. It runs every night after.

Batmail sits on top of Gmail and works the inbox while you sleep: nothing to migrate, nothing to learn, nothing new to check.

03:26On the record

Working in the background. Answering to you.

The bat is staff, not surveillance: it touches only the inboxes you hand it, writes down every archive, label, star, and forward, and leaves without a trace when you say so.

The terms, in plain language

Scoped access, yours to revoke
Batmail holds access only to the inboxes you connect, granted through Google's own sign-in. Disconnect one and its token is revoked and deleted on the spot.
Never training data
Your mail is processed to run your rules and labels, nothing more. It is not used to train AI models, never sold, and there are no ads.
Every action, explained
Every archive, label, star, and forward is logged with a written reason you can audit, and most actions can be undone straight from the activity log.
It speaks only with your voice
Batmail never sends a word on its own initiative. A reply or forward happens only when a rule you wrote says so, and stored tokens are encrypted with AES-256-GCM.

04:52Early access

No testimonials yet.

Batmail is pre-launch, so there is no customer quote to show you and we are not going to invent one. Here is what the night shift does instead: it reads what arrives, archives the noise, labels the receipts, stars the urgent, forwards what your rules route, and briefs you at dawn.

Multi-inbox from day one

Connect every Gmail account you run. One rule can archive, label, or star across all of them, and a single morning roundup covers the lot.

Rules in plain English

Say what to archive, label, star, or forward the way you would brief an assistant. No filter syntax, no boolean builder, no setup wizard.

An audit trail, not a black box

Every archive, label, and star is logged with the reason behind it, and most actions can be undone straight from the activity log.

One email a morning

The roundup lands at the hour you choose, in your timezone, with one-click unsubscribe. It reports what was handled overnight and the few threads that need you.

06:10Questions

Fair questions, straight answers

Batmail reads your mail and acts on it: archiving, labeling, starring, forwarding. So the details matter. Everything else lives in the privacy policy and terms.

What access does Batmail get to my Gmail?

Batmail asks for Gmail read, modify, and send scopes on each inbox you connect. Read is how it triages overnight mail, modify is how it archives, stars, and labels, and send is used only when one of your rules replies or forwards. You can disconnect an inbox at any time, which revokes that access.

Can Batmail send email without me?

Only if a rule you wrote says so. Batmail never composes or sends anything on its own initiative. A reply or forward happens only when an email matches a rule you created with that action. Every send is logged and shows up in your morning roundup.

What does the AI see, and is my mail used for training?

To run your rules and labels, email content is processed through the Anthropic API. Your mail is not used to train AI models. Batmail also never sells your data and shows no ads.

What does Batmail store?

Processed snapshots of triaged messages (so your roundup and audit log work), your rules, labels, and guidelines, and the OAuth refresh token for each connected inbox. Refresh tokens are encrypted at rest with AES-256-GCM.

Can I run several inboxes?

Yes. Batmail is built multi-inbox from day one. Connect each Gmail account you run, give rules a scope (one inbox or all), and get a single morning roundup covering everything.

Does it work with Outlook or other providers?

Gmail only today. Outlook and IMAP support are on the roadmap. If you run a Google Workspace domain, every address on it works now.

What actually happens overnight?

Batmail syncs each connected inbox, reads every new email, runs your rules in order, and applies AI labels with a written reason for each decision. Anything no rule handled is sorted for the roundup, and the digest is assembled before you wake up.

How does the roundup email work?

The roundup is emailed at the hour you choose, in your timezone, and every early access account has it turned on. Every roundup email has one-click unsubscribe, and you can always read the same roundup in the app instead.

How do I leave?

Disconnect an inbox and the token Batmail holds for it is revoked and deleted immediately, along with that mailbox's processed history. Delete your account and all of your data (snapshots, rules, labels, roundups) is removed. No exit interview, no retention tricks.

How does pricing work?

Two plans. Scout is free and covers one inbox with the in-app roundup. Night Shift is $12 per inbox per month and covers every inbox you run, with the emailed roundup and all rule actions. Billing is live and charges immediately.
