<ul>
<li>Contact Form 7</li>

<li>Jetpack/Grunion contact forms</li>

</ul>
No need to modify your forms — just install and activate the plugin.

Dilli Email Validator

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).


BIG waste of money

Validates email addresses in real-time and blocks form submissions with invalid or fake emails. Reduce spam, fix typos, and capture quality leads.
