Interesting, kudos on launching!

How does the email validation work internally?

1 comments

Thanks a lot! Glad you find it interesting!

The email validation performs a number of checks:

- basic syntax

- domain checks

- blacklist checks (e.g. spamhaus.org, etc.)

- mx record checks

- smtp connection checks

- recipient mailbox checks via smtp connection

- disposable email address detection via internal domain lists

- common spam traps via internal blacklists
