The FSF considers protonmail to be "under review"

Proton mail is purported to be licensed under the FSF-approved MIT
license. However, there does seem to be some use of non-free 
I can not comment on whether this non-free Javascript is limiting, 
as I
do not know the details of whether they allow signups or their 
without it, or what their stance is on POP3/IMAP for desktop 
/if/ their webmail does in fact require non-free Javascript.

(That being said, be careful with extensions like LibreJS or 
which while they do block selected Javascript there are some 
that offer Javascript-disabled rendering if your browser tells it 
it does not support Javascript. (see about:config in IceCat, 
Firefox, etc.)

As far as their mobile applications are concerned, they are 
though I do not know if those are written by third-parties who use 
protonmail API or if they are official.

Lastly, make sure to review Protonmails terms of service on data
collection. I am, again, not claiming any knowledge here but just 
to make sure you are thorough when choosing your service.

Reject Zoho. IIRC they have a large contract with Yahoo! for some 
their utilities, services, and possibly data storage. I could be
misspeaking here, so fact check me. I do most of my email work 
offline, so I am not checking this as I go.


I use https://posteo.de/ for my email. They do not offer much 
space for mail, but it is more than enough if you aren't 
attachments all the time. And it is libre, but not gratis.

Finally, join us on IRC sometime. Freenode #parabola
