What's the difference between @proton.me and @protonmail addresses?

Proton has four different email domains that you can use to create email addresses:

• @proton.me is the default domain for Proton Mail. You'll be asked to create a @proton.me address ([e-mail]) when you sign up.
• @protonmail.com is an alternative domain that you can choose when you sign up or use to create additional addresses ([e-mail]).
• @pm.me is our short domain. You can activate your short email address ([e-mail]) after you've signed up, if your username is available.
• @protonmail.ch is our original Proton Mail domain. If you joined Proton before 2016, you have an additional free @protonmail.ch address ([e-mail]).

To activate your @proton.me address, log in to your account (account.proton.me) and click Settings → Go to settings → Identity and addresses.

If you have a paid Proton plan, you can create additional addresses (aliases) using any Proton domain above or your own custom domain (@yourdomain.com).
