My provider mailbox.org keeps last one week’s daily backup (but it does say that that’s an additional gratis feature so no guarantees). Though it has rescued me twice. Once I had nuked all the mails. Other than that all my mail gets downloaded on Mac via Mail.app and I backup that Mac mail folder[0] to rsync.net, borgbase with borg/vorta and to backblaze b2 with restic. That folder is simply part of my laptop backup setup. [0] I know this is not ideal but there aren’t many simpler options.
