MailBoom: Gmail Inbox Cleaner

Clean a massive Gmail inbox without deleting a thing. Group emails by sender, archive in bulk, undo changes, and keep processing private on your device.

Clean up Gmail in minutes—without permanently deleting your email.

MailBoom is a private Gmail inbox cleaner that groups messages by sender, helps you identify what matters, and lets you archive email in bulk. Clear years of inbox clutter while keeping every message searchable in Gmail.

CLEAN EMAIL IN BULK

See which senders are filling your inbox. Sort them into Keep or Archive, then process thousands of messages in batches instead of handling emails one at a time.

NOTHING IS PERMANENTLY DELETED

MailBoom safely removes archived messages from your inbox while keeping them available in Gmail. If you change your mind, undo your most recent cleanup and restore messages to your inbox.

PRIVATE, ON-DEVICE PROCESSING

Your email is processed directly on your device—not uploaded to MailBoom servers. We don’t collect, store, track, or sell your personal data.

SMARTER INBOX ORGANIZATION

On-device intelligence helps categorize senders, summarize inbox activity, and surface messages that may deserve your attention. Review individual emails whenever you want more context.

BUILT FOR LARGE GMAIL INBOXES

Whether you have hundreds or more than 100,000 emails, MailBoom helps you:

• Group email by sender
• Archive messages in bulk
• Separate important email from clutter
• Configure signals, never miss another important email

TAKE BACK YOUR INBOX

Stop scrolling through years of newsletters, notifications, promotions, and forgotten messages. MailBoom gives you a faster, safer way to organize Gmail while keeping you in control of every change.

MailBoom requires a Gmail account and permission to read messages and manage labels. Changes are applied only when you approve them. AI-generated suggestions may occasionally be incorrect, so review important financial, legal, or deadline-related messages directly in Gmail.
