The biggest LOVE/HATE relationship I have is with Gmail
When I forget to include the attachment I promised in the email
I know they're reading my emails
But they saved me some embarrassment

Outlook will invade your privacy and give you the same prompt if you want to switch spooks
Proton really is pretty good and you can have Gmail forward all your emails over so you don’t even need to change previous emails unless you want to. Pretty simple and easy way to try out a more private option on easy mode.
