<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>A free or paid <a href="https://truelist.io" rel="nofollow ugc">Truelist</a> account is required. Sign up at truelist.io to get your API key.</p>
<h3>External Services</h3>
<p>This plugin connects to the Truelist email validation API to check whether email addresses are deliverable. This service is required for the plugin to function.</p>
<p><strong>What data is sent:</strong> The email address submitted through your form is sent to the Truelist API for validation.</p>
<p><strong>When it is sent:</strong> An API request is made each time a user submits a form with an email field. Results are cached for 24 hours — repeat submissions with the same address do not trigger a new API call.</p>
<p><strong>Service provider:</strong> Truelist (https://truelist.io)</p>
