Disabled Proton Mail domain addresses continue to count against your additional addresses limit, whereas disabled custom domain addresses don’t count towards the limit.

Here we explain how to create and use additional addresses, +aliases and SimpleLogin aliases. Learn more about types of email addresses and aliases (new window)

Proton Mail also supports email aliases through our email aliasing service, SimpleLogin by Proton (new window). And all Proton Mail users can create unlimited extra addresses, known as +aliases, by adding “+” after your username in one of your free personal email addresses. If you subscribe to a Proton Mail (new window) paid plan, you can create additional email addresses, also known as aliases, which you can use instead of your free personal email addresses.
