How to add an alias to a Mailbox email account

Reviewed on July 23, 2026

Alias addresses allow you to receive emails sent to multiple addresses in the same mailbox. Aliases help you:

• Sort your subscriptions: create the alias john-newsletter to group all newsletters. Filter and delete emails without impacting the main address.
• Test without exposing the main address: create the alias john-test for a form or integration, and delete it after testing is done.
• Limit exposure on third-party tools: create dedicated aliases (e.g., john-github and john-gitlab) for each tool.
• Spot data leaks: create one alias per service to know who leaked your data if spam shows up.
