<p><strong>Trumailo</strong> verifies every email address submitted to your WordPress site — in real time, with one drop-in plugin — and stops fake, throwaway, mistyped, and risky addresses <em>before</em> they touch your CRM, mailing list, or order pipeline.</p>
<h4>Why bother</h4>
<ul>
<li>Spam signups inflate your list and tank deliverability.</li>
<li>Disposable inboxes (Mailinator, 10MinuteMail, etc.) never convert.</li>
<li>Typo’d emails (<code>gmial.com</code>, <code>yhaoo.com</code>) are lost forever.</li>
<li>Role addresses (<code>admin@</code>, <code>info@</code>) hurt sender reputation.</li>
</ul>
<p>Trumailo catches all of those at the form, with a friendly inline message.</p>
<h4>Works out of the box with</h4>
<ul>
<li>WordPress core (registration, comments, REST users)</li>
<li>WooCommerce (classic checkout, block checkout, registration)</li>
<li>Easy Digital Downloads</li>
<li>Contact Form 7</li>
<li>WPForms</li>
<li>Gravity Forms</li>
<li>Ninja Forms</li>
<li>Fluent Forms</li>
<li>Elementor Pro Forms</li>
<li>Forminator</li>
<li>Formidable Forms</li>
<li>MailPoet</li>

<li>Newsletter (by Stefano Lissa)</li>
<li>Groundhogg</li>
<li>BuddyPress</li>
<li>Ultimate Member</li>

<li>LearnDash</li>
</ul>
<p>No configuration per integration — add your API key, the plugin detects what’s installed and starts verifying.</p>
<h4>Features</h4>
<ul>
<li><strong>Server-side blocking</strong> — survives JavaScript-disabled bots; the rejection happens during form validation.</li>
<li><strong>Real-time inline validation</strong> — debounced typing check with “did you mean” suggestions and accessible status badges.</li>
<li><strong>Per-status policy</strong> — choose what to block: invalid, disposable, risky, role addresses, or anything below a quality threshold.</li>
<li><strong>Whitelist / blacklist</strong> — skip the API for trusted internal domains; always reject specific bad ones.</li>
<li><strong>Cache</strong> — repeat verifications served instantly from local transients (configurable TTL).</li>
<li><strong>Fail-open by default</strong> — if the API is unreachable, submissions go through (configurable to fail-closed).</li>
<li><strong>Verification log</strong> — opt-in, with optional email-hashing for GDPR compliance and configurable retention.</li>
<li><strong>Dashboard</strong> — counts of allowed, blocked, cached, and per-day trend.</li>
<li><strong>REST endpoint</strong> — for custom front-ends and third-party integrations (<code>/wp-json/trumailo/v1/verify</code>).</li>
<li><strong>Multisite-aware</strong>, <strong>i18n-ready</strong>, <strong>GPL-2.0</strong>.</li>
</ul>
<h4>Getting started</h4>
<ol>
<li>Install and activate the plugin.</li>

<li>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Trumailo <span aria-hidden="true" class="wp-exclude-emoji">→</span> paste the key.</li>
<li>Done — every supported form on your site is now verifying emails.</li>
</ol>
<h3>External services</h3>
<p>This plugin connects to the Trumailo email-verification API to determine whether each submitted email address is deliverable. The API is provided by Trumailo (https://trumailo.com), the same vendor that publishes this plugin.</p>
<p><strong>What the service is and what it is used for</strong></p>
<p>Trumailo is a real-time email-verification API. It checks an address for syntactically-valid format, MX records, disposable / role / catch-all signals, and (where the recipient mail server cooperates) an SMTP-level deliverability probe. The plugin uses it so your site can reject invalid, disposable, and risky addresses before they enter your forms, lists, or checkout.</p>
<p><strong>What data is sent and when</strong></p>
<ul>
<li>The plugin sends the <strong>email address being verified</strong> to <code>https://api.trumailo.com/v1/verify</code> over HTTPS, together with your API key in the <code>Authorization: Bearer</code> header. This happens every time a supported form is submitted with a value the plugin hasn’t already cached.</li>
<li>The plugin sends a lightweight request to <code>https://api.trumailo.com/v1/account</code> to read the calling key’s remaining monthly credits. This is used to populate the credits gauge on the plugin dashboard and is polled at most every 5 minutes.</li>
<li>No other personal data, form fields, page URLs, or visitor identifiers are transmitted.</li>
<li>Verification results are cached locally in WordPress transients to minimise repeat API calls; you can configure the TTL and toggle full-email vs hashed-email storage in the plugin settings.</li>
</ul>
<p><strong>Service provider, terms, and privacy</strong></p>
<ul>
<li>Service: <strong>Trumailo</strong> — https://trumailo.com</li>
<li>Terms of Service: https://trumailo.com/terms</li>
<li>Privacy Policy: https://trumailo.com/privacy</li>
