I have mixed feelings about protonmail. On the one hand, they tend to be on the right side of political / legal issues, and this transparency report is nice:<p><a href="https://protonmail.com/blog/transparency-report/" rel="nofollow">https://protonmail.com/blog/transparency-report/</a><p>On the other hand, they recently reduced the level of detail in the transparency report.<p>There is also the fact that they are Swiss, and their privacy laws were severely weakened by a recent referendum. In particular, the Swiss government can now monitor all cross border traffic without a warrant.<p>ProtonMail fought the referendum, but hasn't updated this "Why Switzerland?" page:<p><a href="https://protonmail.com/blog/switzerland/" rel="nofollow">https://protonmail.com/blog/switzerland/</a><p>They also haven't moved to a more appropriate legal jurisdiction.<p>[edit: clarify links]
