Anyone considering a move should also look at NameCrane/CraneMail by the crew behind BuyVM. Solid service, incredibly reasonable prices, great community/discord. They are always looking to improve, extremely proactive and reactive to customer feedback and issues. No builtin PGP, but I believe that is out of their control as they use SmarterMail on the backend.
I would run away from any service that forces me to use discord fr support.
Take it easy. It's not their official support channel. They have tickets like everyone else, with the added bonus that you can nudge them in their chat. You can take advantage of it or not, no forcing involved. The discord is more about community than a support channel. In fact they will usually ask you to open a ticket if you haven't already for direct support issues that don't look to be a general/shared issue.
