Proton – your new short email domain for Proton Mail

This blog was updated on June 20, 2023, to explain that you now need to have a paid Proton plan to activate your short address.

For a long time, some members of our community have been asking us for a shorter, easy-to-share email address. Part of this comes from the difficulty of spelling out P-R-O-T-O-N-M-A-I-L over the phone. Even back in 2015, we started looking into how to support this. It was not an easy task, since the domain name needed to be short, obtainable (not ridiculously expensive), memorable, not confusing, and related to Proton Mail somehow.


Domains that were tried but ultimately rejected included (too easily confused with Gmail), (too easily confused with .com), (unobtainable), (the Swiss government wouldn’t give us this one), and (not quite short enough). Finally, this led us to

We like for several reasons, and ultimately we think it’s a good choice. First, at four letters long, it’s pretty much as short as you can make a domain. Furthermore, it is a clever wordplay, as PM is the universal abbreviation for “private message”, and keeping your messages and communications private (as they should be) is precisely what Proton Mail does. Thus, we like to think of as “private message me” or “Proton Mail me“.

It also helps that .me domains are starting to become more popular and visible (for example, used by Facebook, used by PayPal). In obtaining the domain name, we are happy to have the support of window), the company that manages the .ME TLD for Montenegro. ME domains typically are between 3 and 63 letters, but thanks to their support, we were able to obtain a two-letter domain.

How to use

As a company, we will continue to use as our main domain name. However, if you’re on a Proton Mail paid plan, you can activate a separate email address with your username at no extra cost. For example, if your username is john, you can activate to go with your existing address.

We hope that making Proton Mail email addresses easier than ever to share will contribute to the increased usage of Proton Mail and help to fulfill our vision of an internet where everybody can benefit from the security of encrypted email.
