You can create as many email addresses as you like that all get delivered to a single mailbox.
See our email address page for more details on creating an email address.
When creating your email address:
- Add your canonical email address in the recipient field (that's the one based on your username: USERNAME@mail.mayfirst.org)
- Repeat: you can add as many email addresses with you as the recipient as you like
- The email addresses can be created in your hosting order or any hosting order, even ones not under your membership.
