A bit over a decade ago, I took advantage of Google's free G-Suite, back when it allowed 50 users. I did this both for work (the domain I'm sending this from) and separately for personal use. As a consequence of there being 50 free users I set up several mailboxes for various purposes.
Now that the free service is being migrated to a per-user pricing model I need to change to something else. For work I'll just accept that we've had a good run and pay the subscription charges (albeit we'll likely ditch a few of the users). But for my personal domain - where I am the only user - I want to switch.
I don't need the other collaborative tools (I have a few Google docs/sheets but can migrate them to my work email). But having had it easy for a decade I've lost track of what my options are.
Google has of-course spoiled me with very good anti-spam and I'm reluctant to go down the self-hosted route for that reason although that's not to say it's completely out of the question. (I'm happy running up a hosted VM but wouldn't have a clue what software to use these days, or how to administer it and keep it secure. But I could learn if it was the right approach.)
What do people here use?
(Client-wise I currently use the GMail site - I found it convenient to do that rather so I had a familiar user interface on any PC I might use to check my email. Before GMail I used TBird but that's a long time ago now.)
