The services this email offers is very diverse and a little bit more then anyone else is even coming close to doing. I believe fastmail is the closest thing behind you guys. I am endorsing this 100% and you can look forward to making 1000s off of me. I already am down $150. I will say this though: Listen to my words and my suggestions. Tear my head off or what have you after that, but listen first. The opportunities lost by the refusal of another view point’s knowledge and perspective cannot not be measured. No quantum jokes here.
The persual of the integrated cloud and email should be maintained as well as encrypted phone and VPN/wire guard services. I would advice staying away from the open PgP thing and focus on actual encryptions & ciphers. RSA 4096 bit then ? The PgP will be its own stagnation.
A keyring or vault to store all of this in would be game changing. Do not confuse cloud storage for keyring. You do not lock your keys in your house when you leave on a trip. How else would you get back in? The Yandex.Key is the closest thing I have seen in that direction.
Yandex is another company to inspire ideas from and steer in another direction.
