How to plus aliases work?  Print this Article

This feature, also known as plus addressing, allows senders to route a message directly to the folder of a mailbox.

Email subaddresses use the username+folder@domain format, where username represents the username of the mailbox and folder represents the folder's name.

For example, if you send a message to, the mailserver will route the message to the Important folder in the mailbox.

- If the folder does not already exist, the system will create that folder.
- You must subscribe to the folder in your email or webmail client for the folder to appear.
