I emailed both Fastmail and Proton with the same question before giving them money.
For Proton, I sent the following message:
Hello I am looking to move my self hosted email to a managed provider but I currently have 12 vanity domains.
Even your most expensive plan doesn't allow for that many domains. Is there a way to get approved for more domains? I would like to do the Proton Unlimited plan and would be willing to prepay for two years of service.
For Fastmail is was similar but adjusted to account for their plans.
Proton took 7 days to respond, then, the response I got was just a hand-off to a different team. I never did get an actual answer.
Fastmail on the other hand responded in less than a day, and, had a trial period that let me verify everything I wanted would work.
Fastmail has been about the same for me with speed of response. I don't have to reach out to them often, but when I do it's always quick.
They also don't have a limit on domains. I haven't seen any price gated functionality or any limits. I don't have 12 domains, but I do have a handful and it all works quite seamlessly.
I have been with Fastmail for probably a decade or more now. Worth it.
Probably mostly there to prevent rampant abuse from spammers, scammers, or people just doing really weird shit creating millions of $thing where everyone else has a few dozen or hundred.
Not OP but personnaly I preferred the traditional approach of FastMail who has been in business for long time and are doing only mail while Proton seems too gimmicky to me. Coming from VPN business (and having proved not being that reliable) didn’t help. I just don’t believe their marketing, especially the CERN confusion.
Firstly, yes, Proton started as an email service in 2014, and Proton VPN was added to the offer in 2017.
The case shared above in fact shows that Proton's encryption provides privacy by default - none of the user's emails could be shared with law enforcement despite the data request which we had no legal grounds to contest.
Of course, as any other legally operating company, we have to comply with the local law enforcement. The privacy we provide is reflected in not having access to the data to share with law enforcement, not in refusing to comply (which is not possible for anyone operating legally).
I end up with them because I found it less complicated to set up my email workflow. I also liked the ability, even if not officially supported, to have my tasks/notes/events/contacts synced via there web and card dav server.
I like the webmail more. ProtonMail is slow and doesn't support text view. Also ProtonMail didn't exist yet, and back then FastMail was one of the few options for hosted non-crap email.
I use fastmail because at the time it had calendar and contacts, and proton at the time didn’t. Otherwise I’d use proton for the extra privacy (Eg, company isn’t in Australia)
