Great Plug-In
Easy to use and does exactly what it should. Not overloaded, pretty easy to setup. Awesome ! Works like a charm with Elementor !
Finally the spam stopped!!!
This is FINALLY the solution I was looking for. Thousands of spam emails from my website have been a plague. Now – with this amazing plug-in – it has STOPPED. My gratitude is immense. A real game
Beware: Blocks login
Blocks login even if login protection is not checked in dashboard. Moreover, the right answer does not allow to login. You get locked out your own WP site.
CryptX Reviews
It works. Perfectly!
An essential, lean little helper that goes on every website build that I do. My favorite part: The option to automatically convert pasted mail addresses into mailto-links. Thank you, Ralf!<3
Excellent plugin!
