What email service do you use and why?

Question

Email

What mail service do you consider the most convenient and best?
And the question of which mail service is the most confidential is also of interest, because Gmail is bad in this regard, given that it scans emails for targeted advertising.

Answer 1

There is a new Russian service - sfletter.com. It may lag behind gmail in terms of functionality, but it allows you to send secure emails and attachments, if necessary.
