About Otto Mail

Why Otto exists

Very little of anyone's job is email, and almost all of it passes through email. The meeting that needs booking, the answer three people are waiting on, the promise buried in the fourth paragraph of a thread from Tuesday. The work is not hard. There is simply more of it than a morning holds, and the cost is the hour you spend deciding what each message needs before you do any of it.

AI should be good at exactly that. The catch is that mail is unforgiving: a send cannot be recalled, a delete is gone, and a bulk change lands on a thousand threads at once. An assistant that acts first and tells you later is not something you can reasonably hand your mailbox to.

Otto prepares ordinary assistant actions for you to review. You can also opt into narrow rules for replies or meeting requests, inspect their history and turn them off when they no longer fit.

What Otto does

• Drafts replies in your voice, with the thread and the history already in mind.
• Triages what arrived: what needs an answer, what can wait, what is noise.
• Turns a message into a calendar event, a task or a note without retyping it.
• Keeps accepted commitments and their source links together, including work you are waiting on.
• Runs routines, such as a morning brief, on a schedule you set and delivers them where you read: in the app, by email or push, or in Telegram, Slack or Discord on Plus and Pro.
• Works on the web and iPhone, with Android coming soon, across mail, calendar and tasks.

You can also just read, write and file mail by hand. The assistant is there when you want it and out of the way when you do not.

How we think about it

You choose what can act

Ordinary assistant sends, deletes and bulk changes show a review card before they run. Optional standing rules, such as automatic replies or a booking link, act within the limits you explicitly set and can be turned off.

Your mail stays with your provider

Otto keeps an inbox list with message details so the inbox loads quickly. Message bodies are normally fetched from Google or Microsoft when needed; selected content can also be saved in chats, notes, shared drafts and prepared work you use.

A free tier you can actually work in

Free connects one account with core mail, calendar and tasks, plus an AI allowance. Paid plans add capacity, more accounts and more AI, and core mail is never held back to sell you an upgrade.

Works with the account you already have

Connect Gmail or Outlook and keep your address, your history and your filing. There is no migration, no new inbox to learn and no forwarding tricks.

Your data

Otto does not store your mailbox password or payment-card details. Mail access uses provider OAuth authorization; payments go through our payment provider or the app store.

Otto keeps the mailbox index that makes your inbox fast, your settings, and records for the features you use, including saved conversations and prepared work. The privacy policy describes the content those records can include, how long they stay and who processes them.
