Key Features
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

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.
