I have switched from Google's Gmail to ProtonMail and kMail. I really like both, kMail (by Infomaniak) have very similar app interface to Gmail so you will get used to it very fast and also have big storage for free and very good offers for paid plans 👍🏼
We know Trump for over a decade now. I don't buy this apologist approach to excusing the shitty behavior of people in the spotlight. If you have half a brain you know by now what type of person Trump is and from a CEO I expect more then half a brain.
Regardless, Proton products are a better choice then Google.
From what I understand, that's their way to do e2e encryption between proton emails. They have this bridge thing, which unfortunately you can't use on free plans.
Proton Mail Bridge is a desktop application that runs in the background, encrypting and decrypting messages as they enter and leave your computer. It lets you add your Proton Mail account to your favorite email client via IMAP/SMTP by creating a local email server on your computer.
