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.

Posteo is a very legitimate email provider based in Germany. Your bank is really stupid for flagging and rejecting it, their is absolutely nothing about them that should trigger their systems.
An alternative would be Mailbox, it's very similar to Posteo and I have made good experiences with it.
Why did you switch away from Proton? Most drama surrounding it is very overblown and the consequences of being a large company, not everyone always does everything right who works for them.
