Real-Time Email Validation – Live Check
This plugin uses the Byteplant Email-Validator API (https://www.email-validator.net) for a real-time live check to find out if an email address really exists or not.
Supported Plugins / Compatible Forms
The plugin integrates seamlessly with:
- Contact Form 7
- Gravity Forms
- Ninja Forms
- WordPress registration forms
- WordPress comments
- and with any other form which uses the is_email() function (no changes required).
The plugin can also be easily integrated into any 3rd party forms.
The Email-Validator API real-time validation process includes a live check with all of the following tests:
- Syntax verification (IETF/RFC standard conformance)
- DNS validation, including MX record lookup
- Disposable email address (DEA) detection
- Misspelled domain detection to prevent Typosquatting
- Freemail address detection
- SMTP connection and availability checking
- Temporary unavailability detection
- Mailbox existence checking
- Catch-All testing
- Greylisting detection
We do not send any email to the recipient address during the entire validation process. All processing is done on our servers, your IP addresses and domains are not affected in any way by the Email-Validator service – absolutely no blacklisting risk for your IPs and domains.
