Most Secure E-mail Services

A May 20, 2018 article on Make Tech Easier introduces 10 of the most secure e-mail services for better privacy. As the article says:

"You can’t have too much privacy in today’s all-seeing Internet of big corporations, nosey governments, and “14 Eyes.” (If you don’t know what that is, do your research!) You don’t need to be a criminal not to want your emails spied on, but to have a guarantee of that, you’ll need to find an email service with your privacy as its main concern."

Of the ten e-mail services:

1. Disroot
2. TorGuard
3. Hushmail
4. Runbox
5. Mailfence
6. ProtonMail
7. Tutanota
8. Posteo.de
9. Kolab Now
10. CounterMail

I personally like ProtonMail and Tutanota. I previously used Hushmail, but haven't done so in several years, and no-longer recommend them since they compromised their users e-mail accounts back in 2007.

E-mail is most secure with the above services when it remains on the provider's network (i.e. ProtonMail to ProtonMail), but in all cases you should look for an e-mail service that provides encryption both for messages in transit and while at rest on the e-mail provider's servers.
