<li>
<p data-path-to-node="8,3,0"><b data-path-to-node="8,3,0" data-index-in-node="0">Integrations:</b> Integrate seamlessly with MailPoet and WPForms to verify emails across your entire WordPress site, not just at checkout.</p>
</li>
<li>
<p data-path-to-node="8,0,0"><b data-path-to-node="8,0,0" data-index-in-node="0">Zero Friction:</b> Unlike OTPs (One-Time Passwords), real-time checks happen in the background, so the user never has to switch tabs or check their inbox.</p>
</li>
<li>
<p data-path-to-node="8,1,0"><b data-path-to-node="8,1,0" data-index-in-node="0">Proactive Prevention:</b> It stops “disposable” or “typo” emails before they enter your database, whereas OTPs only verify that an inbox exists (even if it’s a temporary one).</p>
</li>
<li>
<p data-path-to-node="8,1,0"><b data-path-to-node="8,2,0" data-index-in-node="0">Higher Conversions:</b> By removing the “waiting” step, you reduce the drop-off rate typically seen when users get distracted while waiting for a verification link.</p>

<h2>Integrations with MailPoet and WPForms</h2>
<p><strong><img class="aligncenter wp-image-18734006335065 " src="https://woocommerce.com/wp-content/uploads/2025/10/mailpoet_munjr_wpforms_integration-e1771440245354.png?w=896" alt="" width="666" height="208" /></strong></p>
<p>InstaMail Verification extends beyond WooCommerce checkout and registration to verify emails across your entire WordPress site through powerful integrations:</p>
<ul>
<li><strong>MailPoet Integration:</strong> Automatically verify email addresses when users subscribe to MailPoet lists. Verification happens before subscription is completed, preventing invalid emails from entering your lists.</li>
<li><strong>WPForms Integration:</strong> Verify email addresses submitted through WPForms contact forms, newsletter signups, and other form submissions. Configure which forms and fields to check, ensuring only valid emails are collected through your forms.</li>
</ul>
<p>Both integrations use the same verification actions and settings as checkout and registration, providing consistent email validation across your entire site. Enable and configure integrations from <strong>WooCommerce > Settings > InstaMail Verification > Integrations</strong>.</p>
<h2>Real-time protection during checkout and account registration</h2>
<p>Our extension integrates seamlessly with your WooCommerce checkout process, verifying email addresses as customers enter them. No more waiting for bounce notifications or discovering invalid emails weeks later.</p>
