Unfortunately, in the most of cases you can’t Recover A Temporary Email Address. Due to its temporary characteristics, it only lasts for a definite period of time.
We can't you help with restoring your email, but we can help you to learn about how to use restorable mails in the feature with all benefits of temporary emails instead
Feel free to try the new wave of the mailing: anonymous, disposable, recoverable. That's all about ProxiedMail. Create your first proxy-address(e-mail alias) to measure the power of it.
Just create an email alias hosted at @proxiedmail.com, use it and get all emails forwarded to your inbox.
