<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>Identibyte for Contact Forms 7 will detect and block signups and<br />
submissions from disposable email addresses in your forms. Saving<br />
resources for <em>real</em> users allows you to spend time and money on the<br />
users that need it most.</p>
<p>Setting up is easy:</p>
<ol>
<li>Install the Identibyte for Contact Form 7 plugin.</li>
<li>Enable Identibyte validation on any Contact Form 7 email tag.</li>
</ol>
<p>You can use Identibyte for Contact Form 7 completely free without an<br />
Identibyte account and make 20 “checks” per hour. If you need more<br />
checks, you just need to sign up for Identibyte and create a free or<br />
upgraded API token. Learn more below.</p>
<h4>How it works</h4>
<p>When you have Identibyte for Contact Form 7 installed and activated,<br />
Identibyte will validate the <code>[email]</code> tags in your Contact Form 7<br />
forms. All you need to do is add the <code>identibyte:true</code> option to any<br />
    [email] or <code>[email*]</code> tag.</p>
<p>For example, like this: <code>[email* your-email identibyte:true]</code></p>
<p>When the form is submitted, Identibyte will check if the email is a<br />
<strong>disposable email address</strong>. Identibyte has custom technology and<br />
processes for discovering and keeping a highly up-to-date blacklist of<br />
disposable email providers.</p>
<p>And that’s it! Now your signup forms are intelligent and can detect<br />
and block users signing up or submitting information that have a<br />
disposable email address.</p>

<h4>Adding an API token</h4>
<p>If you need to make more than 20 API requests an hour, you can<br />
[sign up for an Identibyte account]((https://identibyte.com/signup)<br />
and <a href="https://identibyte.com/dashboard/tokens" rel="nofollow ugc">create an API token</a>.<br />
Once you have a token, enter it the Identibyte plugin’s admin settings<br />
page.</p>
<p>After the 20 checks per hour are exhausted, if you haven’t entered an<br />
API token, Identibyte will be bypassed and will not fail the form<br />
submission validation.</p>
<h4>What you need to know</h4>
<p>Identibyte for Contact Form 7 relies on making HTTP requests to the<br />
<a href="https://identibyte.com" rel="nofollow ugc">Identibyte API</a>. API calls are made when a<br />
Contact Form 7 form is submitted, for every field that has the<br />
    identibyte:true option.</p>
<p>Identibyte is an external service and has it’s own<br />
<a href="https://identibyte.com/termsofservice" rel="nofollow ugc">Terms of Service</a> and<br />
<a href="https://identibyte.com/privacypolicy" rel="nofollow ugc">Privacy Policy</a>, which you can<br />
