Customer Reviews for Email Blacklist
The Most Robust Solution
CM’s Email Blacklist was the most robust solution out of all of them in the market, so that’s the one I chose. It’s a ‘world of difference’ fewer spammers than we had before installing the plugin.
Killed All Spammers
This plugin works as expected; killed all spammers and false/disposable email addresses which is what I needed for years! No more spammers – wonderful!.
- Works well
Started getting bot registrations so installed to block signups from a specific domain. It works and the list of already blocked domains is very big, all temps emails or spam emails.
- No more spammers – wonderful!

- Perfect and easy
- My site is much safer!
The preemptive domain check is a must for any serious registration system. This was the best solution I could find and it works really well
- Perfect plugin to block disposable (but not only) email
I sent an email asking to modify the plugin to be compatible with my registration form and the team, really very responsive, did it in a few days.
Then I uploaded a file with more than 22000 disposable email domains to block them in my users registration page. The plugins works perfectly without slowing down the registration process
