<p><strong>Truelist Email Validator</strong> connects your WordPress site to the <a href="https://truelist.io" rel="nofollow ugc">Truelist</a> email validation API. It checks every email address submitted through your forms before it enters your database — blocking invalid, disposable, and fake addresses at the point of entry.</p>
<h4>Why validate emails?</h4>
<ul>
<li>Reduce bounce rates on your mailing lists</li>
<li>Keep your CRM and contact database clean</li>
<li>Stop disposable email signups (Mailinator, Guerrilla Mail, etc.)</li>
<li>Prevent fake registrations and comment spam</li>
</ul>
<h4>What gets validated</h4>
<ul>
<li><strong>Invalid emails</strong> — addresses that don’t exist or have bad syntax</li>
<li><strong>Disposable emails</strong> — temporary addresses from throwaway services</li>
<li><strong>Role addresses</strong> — generic addresses like info@, admin@, support@</li>
<li><strong>Failed MX check</strong> — domains with no valid mail server</li>
<li><strong>Non-existent mailboxes</strong> — addresses where the mailbox doesn’t exist</li>
<li><strong>Failed SMTP check</strong> — addresses rejected by the mail server</li>
<li><strong>Bad syntax</strong> — addresses that don’t follow email formatting rules</li>
</ul>
<h4>Supported form plugins</h4>
<ul>
<li>Contact Form 7</li>
<li>Gravity Forms</li>
<li>WPForms</li>
<li>WordPress User Registration</li>
<li>WordPress Comments</li>
<li><strong>Universal mode</strong> — catches email fields from any other form plugin automatically</li>
</ul>
<h4>Features</h4>
<ul>
<li>Real-time inline validation as visitors type (optional)</li>
<li>24-hour result caching — no redundant API calls</li>
<li>Fully configurable blocking rules — enable only what you need</li>
<li>Custom error messages</li>
<li>API key test button in settings</li>
<li>Fails open on API errors — your forms never break due to an outage</li>
</ul>
<h4>Requirements</h4>

<p>Install this plugin into any WordPress system with a working Gravity Forms plugin and all known disposable email address hosts will be rejected and fail validation. This only checks the field type “email” and does not require any configuration or special settings. Its global, if its turned on, then its working.</p>
