Not all temporary email services allow you to recover a previously used email address. However, some Temp Mail websites provide this option, and TempMailU.com is one of them.
If you previously created a temporary email address on TempMailU.com, you can recover it easily by following these steps:
abc12 as the Email Alias and select tempmailu.com as the domain.That's it! If the alias and domain match your previous address, you can access the same temporary email address again and receive new emails sent to it.
