I don't trust Google in the first place, and with the Cloud Act, they can be compelled to provide a user's data.

recommend Safeoffice. We are all going to need to get off Gmail.  
I think the clients are safe though and should not need to change.

I intend to switch entirely to safeoffice in the coming weeks. I am using Hushmail but I want to move to a service set up for providers.

Better safe than sorry. Go with Protonmail

Have you not heard about allthe GOOGLE DRIVES with PORN that have been seized these last couple weeks?

Not just for email, for the database and BL, you really can't beat the price!

I would definitely recommend a SafeOffice account (email is included) as well as a ProtonMail acct.  Get the .ch not the .com as it is more secure. I'm keeping my gmail accts, but am not relying on them anymore.

This article from last year, is a must read about Google.

I have all my contacts in gmail. Very vanilla communication, but I have proton mail and listed it on my site so I can start transferring everyone over there. So many hoops....

I have both for the time being as well for the same exact reason

String and Tin Cans For Me

Heard good things about Protonmail though

I have Protonmail.ch which is even more secure than Protonmail.com and if you pay for your service you have the option to use just pm.me instead of spelling out ProtonMail
each time.  I was using .me until I read about .ch being the most secure.  My email is [email protected]
