Posteo, Mailbox.org, Tutanota, and ProtonMail compared

More Secure Email

Conclusions

Absolute security does not, and probably will not ever, exist in IT – certainly not as long as governments and their services try to control users' data. Only recently, President Obama called for back doors in encryption software [26].

The providers presented here considerably improve security and anonymity compared with the big freemailers, without requiring too much detailed knowledge. However, this will not be enough if you're the next Edward Snowden: In this case, you should look at much more complicated applications, such as I2P messenger [27] or Pond [28].
