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.


Maybe banks flag it because Posteo is a German company and they don’t see it as international? Did you raise a ticket with either your bank or Posteo as you’re paying for both their services?
Thats what I was thinking too. I was considering opening a ticket with my bank but trying to do that with sites like Paypal and my phone company are extra hassles since their customer services feel non-existant.
