<p>BillionVerify Email Validator checks email addresses in real time as your forms are submitted, stopping fake, mistyped, disposable and undeliverable emails before they reach your database. Cleaner signups mean fewer bounces, less spam and healthier email campaigns.</p>
<p>The plugin verifies each address against the BillionVerify API — performing syntax, MX and SMTP mailbox checks — and rejects the submission when the address matches a status you have chosen to block.</p>
<p><strong>Key features</strong></p>
<ul>
<li>Real-time verification during form submission (no front-end changes required).</li>
