There are ways to add more free blocks by adding a review, sharing on Facebook or posting a tweet. Through testing we found that the free plan is more like a trial plan with only up to 5 blocks and after that you are asked to upgrade to their monthly/yearly paid premium unlimited blocking plan. Block Sender has a free plan for individuals to “block a few messages”. The bounce feature is disabled by default and can be turned on from Options by ticking the checkbox for “Send a fake bounced message after blocking”.ĭo note that the experimental “Canned Responses” feature in Gmail Labs must be enabled for the sending of fake bounced messages to work.

Basically this extension allows you to easily move emails to the trash based on sender, domain, subject or a word/phrase by clicking on a “Block” button next to Delete in conversation using Gmail’s filtering system.Īn additional feature found in Block Sender is the ability to automatically reply with a fake bounce informing the sender that the mailbox is unavailable.

Block Sender is an extension for Gmail available for Chrome and Firefox web browsers.
