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.

Daniel ConradieHappy Customer

The applications works wonders and the support team if very efficient, really worth the value.

I've successfully used it for a year and blocked several annoying senders successfully. Thumbs up. Great product.

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

Seamless Integration

All of Your Accounts

Link multiple Gmail accounts, share blocks, and manage all with ease.

Multiple Accounts, Block Once.
Stop wasting time trying to manage filters on multiple email accounts. Create blocks for all your email accounts in one place.
Full Control.
Pause and resume blocking on specific blocks or entire accounts in just a few clicks.
No Limits.
Link any number of accounts, whether it's work or personal (charges may apply), and block unlimited emails.

Flexible Blocking

Control at Your Fingertips

Share blocks between your accounts and 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.
IP Addresses.
Block emails from a given server or network to stop spam from a specific source.
Email Headers.
Block emails based on any of their headers, giving you far more control than Gmail's built-in filters.
Advanced Features.
Do more with your blocks by creating blocking rules with wildcards (i.e. info@*.com) for even better coverage.

Canned responses

Bounce Back to Sender

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

Mailbox Not Found.

Responsible Bounce-Backs.

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