Take back your inbox.

MailDefender is a Chrome extension that finds the mailing lists and spam senders in your Gmail, unsubscribes you from them, and moves their emails to Trash in a click.

Add to Chrome

What it does

Finds mailing lists

Scans your recent mail and groups newsletters and promotions by sender, with a count for each.

Unsubscribes for you

Uses the sender's own unsubscribe option: one-click, an unsubscribe email, or their page.

Bulk clean-up

Move every email from chosen senders, or your whole Spam folder, to Trash. Trash keeps mail for 30 days.

Banner in Gmail

Open an email from a mailing list and a banner lets you unsubscribe or clear that sender right there.

Your data stays with you

MailDefender runs entirely in your browser. We have no servers, we never receive your email, and nothing about your mailbox is sent to us or to anyone else. It reads only message headers (sender and unsubscribe information), never the contents of your emails. Read the full Privacy Policy.

MailDefender's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
