My website received hundreds of spam messages. After installing the plugin, I have not received spam messages.

Using the free 100 validation took 5 minutes having 10 logins only on my site. Each login (not registration! login!!!) used 5 validations. I see no sense in validating logins (well, it makes sense for the provider asking 0.5 cents per validation). Even my admin user's (already logged in) ajax calls were validated each time. And the worst is that it blocked valid users logging in with an email address from free email providers (not disposable).

The Dilli Email Validator plugin is a necessity for all WordPress sites. Since installing the Dilli Email Validator on our website, there has been a significant decrease in spam submissions on registration forms and comment sections. Brilliant!

We've been using Dilli Email Validator for some time now and it is very important for our business. We've tried several different validation tools and are most impressed by this one. Great product, give it a try and you won't be let down.
