Indeed, the company has been a global leader in rolling out secure technologies.
The Guardian
Make an account with German service Posteo instead of with Googlemail.

With Posteo, the user sets up their account anonymously and also pays anonymously. Posteo even implements two-factor authentication (2FA, a security feature) anonymously.
Stiftung Warentest
Berlin company Posteo has this Monday presumably become the first email provider in the world to implement modern DANE technology, which ensures encrypted transport of emails.
Heise
Posteo is not merely a commercial project. Its absolute commitment to privacy shows that communications providers can also think and act politically.
Deutschlandfunk
Posteo works with all current encryption methods. Above all else, it collects as little data as possible from its customers.
FAZ
There are many email providers, but Posteo stands out from the crowd. The small Berlin company not only operates with optimum security and privacy, but also has an especially sustainable philosophy.
Ökotest Verlag (Markt und Medien)
Certificate pinning is a relatively new standard, which works towards restoring trust in encryption on the web. (...) Posteo is now the first larger German provider to test this concept in practice.

Chip
Most reports and articles concentrate almost exclusively on Posteo's stance on privacy and data security. The plan to establish an alternative email provider originally arose out of an ecological motivation.

Privacy is ensured by encryption and IP stripping, whereby Posteo’s server replaces your IP with theirs anytime you send an email. Also, no ads are served nor is user data tracked.
