<p>This plugin integrates with the Dilli Email Validation API (DEVA) to block fake or incorrectly formatted email addresses at form submission, ensuring higher-quality leads and significantly reducing spam.</p>
<p>This plugin requires an API Key which can be obtained for FREE by <a href="https://deva.dillilabs.com/register" rel="nofollow ugc">signing up here</a>. Learn more about Dilli Email Validation API <a href="https://www.dillilabs.com/products/email-validation-api/" rel="nofollow ugc">here</a>.</p>
<p>This plugin hooks directly into the WordPress core email validation function (<code>is_email()</code>), which is used by most major form plugins. That means it works out of the box with popular form builders like:</p>
<ul>
<li>Contact Form 7</li>
<li>WPForms</li>
<li>Gravity Forms</li>
<li>Ninja Forms</li>
<li>Jetpack/Grunion contact forms</li>
<li>WordPress registration forms</li>
<li>and many others.</li>
</ul>
<p>No need to modify your forms — just install and activate the plugin.</p>
<h4>Features</h4>

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.
