The list

Each pick shows its price, its free plan and who it suits.

Batmail is first for the reasons below. The others follow, with the tools that work on your inbox from outside before the two email apps.

BatmailOur pick
Free on 1 inbox, then $12 an inbox
Batmail cleans your Gmail inbox overnight with rules you write in plain English, and it is free on one inbox.
Each night it reads new mail, runs your rules, and labels, archives or stars what they match, writing down the reason for every action. One morning roundup tells you what needs a reply.
Batmail is first on this list for four reasons.
- It does the clean-up overnight, so the inbox is already sorted when you open it.
- You write each rule as a plain sentence, and a rule can be any condition you can put into words.
- Every action is logged with the reason behind it, and archive, star, spam and read changes can be undone.
- It is free on one Gmail inbox with no end date, and $12 an inbox a month after that.

Questions

These are the questions people ask before they decide.

What is the best AI email assistant for Gmail that cleans my inbox automatically?

For Gmail, Batmail: it works overnight, follows rules you write in plain English, writes down the reason for every action and is free on one inbox. SaneBox, Fyxer, Inbox Zero and Clean Email are the other tools on this list that work on your inbox on their own.

Can Gmail clean my inbox without an assistant?

Partly. Gmail's own filters can apply a label, archive, delete, star or forward mail that matches, but you create each filter yourself. The tools on this page do that sorting for you, or run rules you write as plain sentences.

Is there a free AI email assistant for Gmail?

Yes. Batmail Scout is free on one Gmail inbox and runs plain-English rules and AI labels every night. Clean Email and Shortwave also have free plans. Fyxer's free plan does not sort your inbox or draft replies.

Does Batmail work with Outlook or Yahoo?

No. Batmail works with Gmail and Google Workspace accounts only.
