I recently started migrating my email and went with mailbox.org. I opted for it based on it having a good balance of ethical/environmental stances, support for custom email domain (so email doesn’t feel like vendor lock in in the future), and a business model focusing on paid service.
There were a lot of options but ultimately I just wanted something “good enough” rather than spending weeks on comparing. A part of that decision was realizing I didn’t care about getting something with the best possible privacy - email is predominantly an insecure medium and things with E2EE work only if the recipient is in the same ecosystem, which is rare. In practice I’m not going to trust anything sensitive to email regardless, so I might as well prioritize picking something that looks like a decent and stable balance.
Mailbox.org has calendar but I haven’t really played with it much. I’m realistically going to look in to look in to something self hosted since I will require more features than most email providers will offer, so I don’t want to tether the two services. That was a part of the reasoning for Mailbox.org over something with more services - I wanted email, not something trying to be the next ecosystem - that’s what I was trying to get away from!
Trump is shit, and he’s spewing shit, but that doesn’t make this a shitpost.
