Truelist Email Validator 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.
<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>Invalid emails — addresses that don’t exist or have bad syntax</li>
<li>Disposable emails — temporary addresses from throwaway services</li>
<li>Role addresses — generic addresses like info@, admin@, support@</li>
<li>Failed MX check — domains with no valid mail server</li>
<li>Non-existent mailboxes — addresses where the mailbox doesn’t exist</li>
<li>Failed SMTP check — addresses rejected by the mail server</li>
<li>Bad syntax — 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>Universal mode — 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>
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.
<h3>External Services</h3>
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.
What data is sent: The email address submitted through your form is sent to the Truelist API for validation.
When it is sent: 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.

The Temp Mail Detector WordPress Plugin is a privacy-first temporary email prevention plugin which helps stop disposable emails from being able to sign up or comment on your website. With built-in WooCommerce support, you can also protect your store from fraudulent orders and registrations using disposable email addresses.
By combining the ability to use your own custom blocklist alongside the optional Temp Mail Detector database, you can choose which email providers are allowed or not allowed to use your website.
<h3>What’s available</h3>
This plugin offers multiple options: 
* Blocklist – You can enter your own list of domains to block. 
* Protect comments – Choose if you would like the plugin to mark comments as spam. 
* Protect WooCommerce – Block temporary emails during WooCommerce checkout, customer registration, and account updates. 
* Plus emails – Block emails which have a <code>+</code> in the user part. 
* External check – This makes use of the live Temp Mail Detector database for real-time checks.
To check against the Temp Mail Detector database, you will need to <a href="https://tempmaildetector.com" rel="nofollow ugc">register for a free API key</a>. 
Each API key gets 200 lookups each month, which reset on the first of the month.
<h3>Where Temp Mail Detector Protects Your Site</h3>
Temp Mail Detector automatically blocks disposable email addresses in these common situations:
WordPress Protection: 
* Someone creates a new user account → Signup is rejected 
* Someone leaves a comment → Comments are automatically marked as spam 
* A user updates their account email → Changes are blocked
WooCommerce Protection: 
* A new customer registers → Account creation is blocked 
* A customer makes a purchase → Order is blocked 
* A customer updates their account email → Email changes are prevented 
* Customers use the checkout form → Checkout is blocked
<h3>External services</h3>
If external checks are enabled via the use of an API key, when checking if an email is temporary or not through the Temp Mail Detector API, only the website address of the email is sent to be analysed. Your users’ email addresses are never transmitted or shared with anyone.
If an email is <code>user@website.com</code>, this plugin will only send <code>website.com</code> to be analysed. By never sharing your users’ emails, you can both check if an email is disposable while also maintaining your users’ privacy.
