How does it work
The email verification service performs 4 checks when an email address is sent to be validated.
- Syntax checks: Verifies if the email address is formatted correctly. An email address must have a username followed by the @ symbol and a domain with a valid suffix such as .com, .org or .net.
- Domain checks: Verifies if the domain is configured with an MX record pointing to a valid mail server to check if it can send and receive emails.
- Server checks: Verifies if the email address is registered on the mail server by checking the SMTP connection. This makes sure that the address exists and is accepting incoming emails.
- Rules checks: Verifies if the email address matches your filter settings. For example, you can only allow non-disposable addresses, restrict catch-all or group emails.
