Not only does this seem to not work but it appears to have been caught up in multiple "no-reply" email back and forths which have resulted in my gmail account being temporarily suspended from sending emails. I have sent an email to the site requesting cancellation and details so no need to reply asking me to send an email.

This extension is brilliant! It gives provides the ability to block spam by pretty much any field you like: AND IT WORKS BEAUTIFULLY. It does lack the ability to select all or multiple blocks and thus change the settings for them en-mass, rather than having to change each block individually which is tedious and time-consuming. I'm confident that the developers will agree and add this simple functionality boost soon.

I added this extension to block spam emails and I had high hopes but after adding the extension and removing it a few times to try and refresh it, I still only see part of the corner box of operation and makes it very difficult to use. I have since removed this extension and will be looking at another extension.

Bis jetzt habe ich bei Gmail keine Möglichkeit gehabt Spam-E-Mails zu blocken. Nun, mit "Block Sender" habe ich endlich ein Werkzeug, um diese einfach und sicher abzustellen. Bisher beste Blockiersoftware für Gmail. Finde ich super!

This just doesn't work. Tried to add bounce back rule for a gmail email address and then tested it. The test sent email just goes into a void and doesn't bounce. Paid for plus and no response from support when I contact them through website. Avoid.

Para nosotros si trabaja muy bien. Usamos la versión PRO. Pero no es bloquear por bloquear, se debe analizar el correo original en formato hmtl y desde ahí, se entiende a quien voy a bloquear, sea IP , Domino o email, previa revisión del origen de los datos.

I installed the Blocksender.io Extension. I DID set it up with maximum security settings. And my Gmail already had maximum security settings. But GET THIS: WITHIN ONLY 48 HOURS of installing Blocksender.io as an extension on Chrome, TWO (2) of my passwords were shown as BREACHED. I suspect that the CAUSE of the two breaches was (is) Blocksender.io. Has anyone else experienced this?

I would wager that a lot of these folks leaving bad reviews don't understand how to configure it properly so it does what it's supposed to do. So far as people saying it should be free--why? It costs them money to run. That said, I come from a family and extended family that is at times abusive and very, very difficult and sometimes I need to be out of reach to them. This software blocks emails from them perfectly--normally I use the "delete" function so they don't even go to trash--I simply never see them at all. Its good for managing the crazy people in your life when you have to deal with them but sometimes need to simply be *away*.
