Recovering a deleted email address or account typically requires the following steps:

1. Identify the email provider or service: The first step is to identify the email provider that was associated with the account in question. Once you know the provider, you can find out the specific steps to recover a deleted account.
2. Check Recycle Bin: The second step is to check the recycle bin for the email account. It's possible that the sender accidentally deleted the email account in question. In this case, simply restoring the account may be enough to recovery the email address.
3. Contact Email Provider: If this step fails, the next step is to contact the email provider. Depending on the provider's policy, they may be able to restore the deleted account or help you recover the data associated with it.
