I’m trying to de-Google my life and self-host more. One tricky point with me is calendaring. I can get a CalDav server running and syncing with my Android phone without much hassle, but I haven’t yet found a server or client that can send e-mail reminders for events, rather than just pop-up notifications.

I’ve been told to try Nextcloud. I tried installing it but it’s overkill for me, and I don’t want to deal with setting up a domain. Surely there can’t be exactly one CalDav option that can send email reminders. But I’ve never heard anyone say anything other than “Nextcloud.”
