@freddy I haven't tried it, but the marketing is very slick. However, two things perplex me.
I am uncertain why email needs to be 'faster.' If anything, I need to slow down my email processing to give more time for a considered answer.
Two, I see a lot of text about how they can and will use a customers data, but little about how they protect and secure it. In other words, there doesn't appear to be an E2EE?
