I switched from Gmail to Proton, but now with everything coming out about Proton I’m switching from them too. I started using Posteo which I like but a lot of my accounts having to do with money and finance (including my bank) aren’t accepting the Posteo email. They have rejected it over and over and even locked me out stating that I was hacked.
Do you guys have any recommendations for email providers to use that also won’t send red flags to my more official accounts?
If it helps, I’m US-based.


Consider getting your own domain name and pointing it at a provider, then when they enshittify you just switch provider and don’t have to change all your emails everywhere again.
This is how I use Proton. The setup process is really easy with clear instructions on what to configure in your DNS provider.
The only problem I have is that gmail rejects emails from my domain, I have to use proton’s address.
You need to build up reputation before you can beat spam filters. This happens all the time to new domains. Make sure to have Dmarc and Dkim configured.
How do I build up reputation? Should I keep trying to send from that domain even if it gets rejected?
I have all the DNS things configured as per Proton’s instructions.
Well, that sucks. Guess you must hate the people who reject you. What domain? yy?
Yes, but normally I don’t send a lot of emails anyway.
If I send to any @gmail.com address, it’s rejected, unless I change the From to my @proton.me
Huh I never thought about this. This is something I’ll have to do some research on, thanks.
Go for it. It’s surprisingly easy, relatively inexpensive and gives you way more control.
Well proven strategy, to the point where most providers explicitly allow it (might even be a decider). But don’t trust me (genuinely), Moar research! (please)).
BRILLIANT!!!
Well… it has advantages, for sure. Also drawbacks. A custom domain, that ties together all your separate email addresses.
There are let’s say 16 addresses on mysuperbestnumberonemail dot com. One used at a bank, one on a shopping site, 4 on a social media site, and one each at some utilities. Those are the ONLY uses of that domain for email in the whole world.
Where if it’s a domain millions of others use, then addresses are harder to pinpoint down to one person.
That might matter to someone. Or it might not. Depends on what you care about. Just something to be aware of. A custom domain is a huge fingerprinting signal.
I would advise mainly using a generic {hello,mail,<domain>}@domain.tld as that reduces the bits of information that can be gained about its use®, and consider WHOIS data. Most registrars hide that information from the public but it’s still subject to court orders - always check what legislation a given TLD falls under. There are also some registrars that are fully anonymous.
