How MailDefender unsubscribes you from Gmail mailing lists, what it can see, and how cleanup works.

Add to Chrome

The basics

What is MailDefender?

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.

How do I unsubscribe from many Gmail newsletters at once?

Install MailDefender, let it scan your recent mail, then select the senders you want to leave. It uses each sender's own unsubscribe option and can move their existing emails to Trash.

How does MailDefender unsubscribe me?

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

What is the banner MailDefender shows in Gmail?

When you open an email from a mailing list, a banner appears so you can unsubscribe or clear that sender right there, without leaving the message.

Clean-up

Are deleted emails gone forever?

No. MailDefender moves emails to Gmail's Trash, which keeps mail for 30 days, so you can restore them during that period.

Can MailDefender clear my Gmail Spam folder?

Yes. It can move your whole Spam folder to Trash in one click.

Privacy

Does MailDefender read my emails?

No. It reads only message headers (sender and unsubscribe information), never the contents of your emails.

Does MailDefender send my data to a server?

No. MailDefender runs entirely in your browser. It has no servers, and nothing about your mailbox is sent to MailDefender or anyone else. See the full Privacy Policy.

How is MailDefender different from cloud-based unsubscribe services?

Many inbox cleaners connect your mailbox to their own servers. MailDefender has no servers: everything runs locally in your browser, it sees headers only, and no mailbox data leaves your computer.

Compatibility

Does MailDefender work with Outlook, Yahoo or other email providers?

No. MailDefender is built for Gmail in Google Chrome.

Is MailDefender affiliated with Google?

No. Gmail and Chrome are trademarks of Google LLC. MailDefender is an independent product.
