The Alias Addresses settings page displays all email addresses (a) that have been created for your mailbox:
You can also define any of these email addresses as the default address (b) by clicking on the wrench icon next to the address. The default address is used as a sender address when you compose, reply to or forward an email. You can also set the sender address for an individual email.
Your sender name will be added to each email you send out. When selecting the default address, you can set it so that your name is not sent with the email by default (b). You can also prevent your name from being sent with an individual email.
Existing email addresses cannot be changed. However, you can delete the email address and create a new one.
If, for example, you have gotten married and changed your name, we recommend the following: Create a new mail.com email address with your new name and set it as the default address. Keep the old email address until all your contacts use the new email address. Then delete the old email address.
You can log in with any email address you have created for your email account. Your mail.com password applies for all addresses. If you need a separate password or a separate inbox, you have to register a new mail.com email account.
If you delete an alias address, we cannot guarantee that the account will become available again.
