We have given this quite a bit of thought, but at the present moment, it is not clear the advantages would outweigh the disadvantages.
The biggest problem is search. Encrypting all metadata would break metadata search entirely on the web client as there is still no efficient way to handle search of encrypted data within a browser.
Secondly, metadata encryption’s value from a privacy standpoint is also somewhat dubious. Because we ultimately must deliver the message to the recipient, we must know who the recipient is. At the current time, there still isn’t any proven and viable way to work around this.
Metadata encryption is an area of continued research for us, and when the opportunity arises and the technology for doing this matures, we will definitely implement it in ProtonMail.

I agree that encryption of all metadata is a must since to many of the state sponsored threats are less worried about what is being said as they are about who is talking to who ProtonMail could even do this easily by having its servers understand that an email from protonmail to protonmail does not even need to be sent out but could be delivered inside the server so that an unencrypted version of metadata never needs to be released online. There was an artical published about a reporter that emailed a Tibetan monk which set off an attack on his email be a suspected Chinese agency if protonmail mail supported this and they both had protonmail accounts there would be no way to know that they were even communicating.
