With our plugin, quickly block emails directly from your inbox.

Block Sender


Block newsletters, spam, stalkers, and even bounce emails back*.

Flexible Blocking

Out-smart the spammers with a wide range of email filters.

Email Addresses

Someone bothering you? Simply block their address discretely with just a few clicks.


Newsletters you can't unsubscribe from? Stop their messages without unsubscribing.


Not a fan of men's health products? Filter out emails with commonly used spam words.


Gmail spam filters don't work on that crazy ex of yours, but Block Sender does.


Tired of "Nigerian prince" schemes? Block scammers from your inbox, no matter how much "money" they promise you.

Advanced Features

Do more with your blocks by creating blocking rules with wildcards (i.e. info@*.com) for even better coverage.

And many more...

These are just a few ways you can keep unwanted email out of your inbox.

Bounce Back to Sender

Fool the sender in to thinking your address doesn't exist.

Mailbox Not Found

Don't change your email just to stop one person from emailing you. Bounce back their messages with our authentic-looking error messages.

Responsible Bounce-Backs

We only send bounce-backs to verified senders to help prevent creating more email spam.

Fake Bounce, Real Results

The bounce-backs may be fake, but to laymans they look like the real thing.

Private and Secure

We prioritize the privacy and security of your data.

Privacy First

Your email data will never be sold or shared with anyone, and it's never even stored on our servers.

Approved by Google

Our servers, networks, and processes are routinely audited by a Google-appointed security firm to verify the security of your account.

Sustainable Business

By charging for our plus/pro plans, we don't need to rely on selling your data to stay in business.

Makes this process very easy and will prevent you from getting inundated with pointless emails

Ryan Bushey,
Business Insider

Gmail does an excellent job of blocking spam, but sometimes you just want to go the extra mile and prevent some mail from ever reaching your account.

Dave Greenbaum,

I didn’t know quite how much this could become a valuable part of my daily Gmail routine until I started using it. Thanks!
