Are you using it (Proton Mail) with BI? I thought the only way to do that is with the paid account - not the free account.Yep. I have used it for over 2 years. It works fine, has phone apps, it's free and Google can't get into it and then plaster ads all over my internet, based on what discussions I had in my Gmail account about a product 3 minutes before. I have multiple addresses. One is just a burner account I use when I sign up for something and you have to give them an e-mail account. I never look at it. You can set them up to purge things in the inbox after so many days, etc, etc.
