Mail.ru Email Verification

Mail.ru is one of the largest email providers in Russia and the CIS, serving @mail.ru, @bk.ru, @inbox.ru and @list.ru.

How Mail.ru Handles Verification

Mail.ru servers usually reject unknown recipients with a 550 during the SMTP session, similar to Yandex, so mailbox existence is verifiable for most of their domains. Greylisting and rate limiting are common.

What Mailthentic does

We complete the SMTP handshake, interpret the RCPT TO response, and apply greylisting retries and MX-cluster throttling so Mail.ru results are accurate and respectful of their limits.

Best Practices for Mail.ru

  • SMTP results are usually reliable. A 550 typically means the address does not exist.
  • Handle greylisting. Retry deferred attempts after a delay.
  • Verify at a steady pace. Aggressive probing can trigger temporary blocks.
