About Clean Inbox for Gmail™
What Is Clean Inbox for Gmail
Clean Inbox for Gmail™ comes from Codemoon, the small studio behind Unsubscribe for Gmail™ and Guard Email for Gmail™. It runs as a Gmail add-on, opens in the side panel of your inbox, and builds real Gmail filters rather than hiding messages inside its own interface. Google's Workspace Marketplace lists it at 4.6 stars across 209 reviews and more than 50,000 users.
The clutter in most inboxes is not spam. Gmail catches that already. What buries you is mail you half agreed to years ago: store newsletters, product announcements, review requests, calendar invites from tools you tried once. Writing a filter for each sender is tedious, and most people stop after the first five. This add-on takes the opposite route. You describe the mail you don't want in a sentence, and it returns the filter that catches the whole category. That is the core idea: an AI email filter that learns the shape of the category, not one address at a time.
Two limits matter before you install. Filters act on new mail only, so a full backlog needs Gmail's own export and import pass, which the add-on walks you through. And the AI suggestions still deserve a look before you switch them on, because a category that is too broad can catch receipts or client mail. The free tier stops at five categories.
Getting Started
- Install the add-on from the Google Workspace Marketplace with the Google account you use for Gmail. No card is needed for the free tier.
- Open Gmail on the web, click the Clean Inbox icon in the right side panel, and finish the short setup screen.
- Describe the mail you want gone in plain words, or open a message and let the classifier name its type. The add-on drafts a filter for you.
- Review the filter, then switch it on. Choose what happens to matching mail: a label, an archive, or straight out of the inbox.

Key features
Filters written from plain English
You type something like "anything from clothing stores with a sale in the subject" and the add-on returns a working Gmail filter. No syntax to learn, no sender-by-sender rules to maintain. The result is a normal Gmail filter, so it keeps working whether or not you open the add-on again.
AI classification of the message in front of you
Open a message and the model reads the subject line and sender, then names the type: newsletter, promotion, review request, forum digest, service notice. That label is what lets the tool catch new senders in the same category instead of matching one address at a time. Subject and sender are the only fields it sees, and only while the panel is open.
One-click category blocking
The add-on ships a library of email categories you can switch off in a single click. Newsletters, promotions, review requests, terms and privacy updates, and service announcements each have an entry. It is the fastest route to inbox zero for people who don't want to describe anything in words.
Sender, domain, and always-allow lists
Block one address, block an entire domain, or keep a sender on the always-allow list so nothing important gets caught. The paid tiers remove the 10-contact caps, which matters once you start blocking agencies that rotate addresses. Community blocked domains add a shared list of senders that many users report as unwanted.
Label maker and automatic filing
Filters can auto label emails, file them into folders, mark them read, or skip the inbox entirely. The add-on creates the labels its filters need, so you don't build the folder tree first and hope the rules match it. It doubles as an email organizer, since the archived mail ends up grouped by type instead of piling into All Mail as one flat stream. Decide once and the sorting runs from then on.
Shared category lists
You can publish the categories you build and install lists other people published. Popular lists cover retail, SaaS, and job boards. It turns a private cleanup job into something closer to a community filter pack, and the lists keep the same structure your own filters use.
Pros and cons
Pros
- No mailbox read access: the add-on requests message metadata only, so the AI works on subject lines and senders, not the body of your mail.
- AI stays inside Google Cloud: the model is Gemini, running in the same Google Cloud project as the add-on, and subject lines are never forwarded to OpenAI or another vendor.
- Filters outlive the tool: everything it creates is a native Gmail filter, so your setup survives if you stop paying or uninstall.
- Free tier is usable: five categories, 10 blocked and 10 allowed contacts, and standard AI speed cover a light inbox without a card.
- Existing mail has a path: the bundled export and import walkthrough applies your filters to old messages in one pass.
Cons
- Filters only stop new mail: an inbox with years of backlog still needs the manual Gmail export and import step, which takes a while on large accounts.
- Free tier caps bite quickly: 5 categories and 10 blocked contacts run out for anyone with a busy work address, so the paid step comes sooner than expected.
- AI suggestions need review: a category read too broadly can catch receipts, invoices, or client mail, and you only find out after mail goes missing from the inbox.
- Gmail only: there is no Outlook, Apple Mail, or IMAP support, and no public API for building custom workflows around the filters.
Frequently asked questions
Yes, there is a free tier called Hobbyist. It covers 5 categories, a limited set of public categories, 10 blocked contacts, and 10 allowed contacts. Professional and Lifetime plans add unlimited categories, unlimited block and allow lists, and priority AI response.
