Ok Yahoo or Mail.ru Emails Bouncing

Why some Ok Yahoo or Mail.ru emails bounce and what can be done with them?

During email verification, we can tell if an email address exists. We do this with a so-called SMTP connection. We create a connection with the recipients' servers and initiate an SMTP connection. This is the same connection that is used for email sending. The only difference is that we do not send an email. 


Yahoo and Mail.ru have recently disabled a large number of accounts. The email accounts still exist; hence we detect them as Ok, but they send a bounce message due to account inactivity.

When verifying those accounts, we get an Ok response, but when an actual email is sent, they send a bounce message that the account is disabled. 


This affects only a small % of Yahoo's and Mail.ru's ok emails, but be aware that this might happen. The only way to get this response from Yahoo and Mail.ru is by emailing those accounts. We never send an email during email verification, as we would be spamming your subscribers.


When can I use Yahoo and Mail.ru OK emails?

If your subscribers are real subscribers and have recently subscribed, you can use them.


When should I not use Yahoo and Mail.ru emails?

If you use an old database or collect emails from the internet, it is better not to use Yahoo and Mail.ru emails.
