MailCheck.ai

This plugin works great!  The service works well, nothing is 100% and won't block all temp emails but it gets updated frequently and new domains are added all the time.  I would recommend this plugin for everyone who allows registration on their site.

Works Great!

No options, light weight and effective addition to combat spam and account creation. And to boot, it seems to work very well on Multisite too!

Simple and effective

Prevent disposable email addresses from registering or commenting on your site with MailCheck.ai.
