This plugin uses the Byteplant Email-Validator API (http://www.email-validator.net) to check if an email address really exists or not.
The plugin integrates with the is_email() function of WordPress. It works seamlessly with:
- Contact Form 7
- WordPress registration forms
- and with any other form which uses the is_email() function (no changes required).
The plugin can also be integrated into 3rd party forms that do not use the is_email() function.
How does it work?
The Email-Validator API real-time validation process includes 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
The plugin requires an API Key (free, no credit card required):
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.
We are committed to protect your data and your privacy when processing personal data.
We do not process or store email addresses for any purpose other than validation.
We do not share any client data with any third party at any time.
We keep all data supplied by clients for the purposes of validation as confidential, to not disclose data to anyone within our organization without a need to receive it for the specific purpose for which its is being disclosed to us, and to not disclose this data to any third party.
Byteplant is located in Germany and operates according to the German Federal Data Protection Act (BDSG) and privacy legislation which is one of the strictest in the world (see http://en.wikipedia.org/wiki/Bundesdatenschutzgesetz for details).
Personal data according to the German Federal Data Protection Act means any information concerning the personal or material circumstances of an identified or identifiable individual. This includes your name and address but also data like your phone number and email address. All data is subject to a special protection in accordance with the German Federal Data Protection Act and other legal provisions which we enforce using both technical methods and strict company processes.
- Do you store validated email addresses?
All data from API requests and batch/list processing will be automatically deleted within 14 days after the data has been processed.
In order to use this beyond 100 address checks, you need to PAY. Also, to use the free version, you need to REGISTER and get an API key... which means "extra, unpaid work for you" I keep looking... for a truly free plugin
Great plugin very useful. 🙂
