Is there an Email Client with OpenPGP support on iOS?

I hate email, because I haven’t wanted to deal with this I’ve been using my university Microsoft 365 for everything, which I’m recognizing is probably a bad idea. I was interested in Mailbox Mail because it was cheaper than Proton, and I’d prefer to self-host my calendar and storage. The issue is I’d like to use OpenPGP if I’m going to be paying for an email provider, but I’m still on iOS and the stock app doesn’t support OpenPGP, is there a client that does? Does it even matter if I use encryption since nobody else does? Is it just worth sucking it up and paying for proton at least until I switch to android?

Thanks for any help!

Canary Mail? I don’t believe it’s recommended, but it’s probably the only option for iOS.

Re mailbox, I’d search around here and elsewhere too see if you’re happy with trade-offs involved. Opinions about it are split.

I currently use mailbox, but I don’t use encryption pretty much for the reasons you outlined. I just can’t be bothered and there are better mediums for comms anyway. I’m considering switching to Proton mainly because it has decent security and a nice web app. I love that it is “zero-knowledge” out of the box, but I don’t really care about actually encrypting my comms over it, and neither should anyone else, but that’s just my 2c.
