I think we all know encryption in term of emails is hard to read. Take encryption.Example, when an email failed to deliver and sit in retry queue, where is it on? on Redis, on disk? Is it encrypted or now? If it's encrypted how the search works? One thing that I really appreciate is that I can reach ProtonMail support to asked why they flagged my email as spam. I build an email forwarding service https://hanami.run https://hanami.run and when we first rolled out I reached out to them, they explain to me my entire email looks good and problem is probably by the age of domains. A few weeks later our emails are no longer flagged as spam. I couldn't get that kind of support from gmail or outlook. They also maintain https://github.com/openpgpjs/openpgpjs https://github.com/openpgpjs/openpgpjs so I think ProtonMail still deserve some credits
