But for simplicity and clarity, we will call them additional addresses. Sometimes, additional addresses are also referred to as aliases. If you have a paid plan, you can create at least 10 additional addresses (depending on your plan) with any Proton domain or or a custom domain (new window), if you have one. 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).
