My testing hasn’t been exhaustive, but thus far, this plugin works perfectly! Looked up a few temp email generators, used them to try to register on my site and wasn’t able to. Was curious about what would happen if I used an email service which isn’t technically a disposable email site but is commonly used when people don’t want to give out their real email and was pleased that the core domain still allowed people to register, but none of the alias addresses provided by that same service would work (which is exactly what I want). Great job!

Simple plugin connected to a free service that just works. No configuration, no API key, no nonsense. Thanks much!

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.
