Yeah I laughed when I saw he'd moved to MS, but I'd love to get some more alternatives.
My ISP has already said they're going to stop providing email service at some point in the near future and I'll have to migrate at some point. In the past I'd picked up a cheap domain and self-hosted for a bit, but I'd love to not have to. Any good email providers out there that actually respect their customers and support IMAP?
I moved my personal email from Google a few years ago to https://inbox.eu which was by far the cheapest option for mailboxes for the whole family on custom domains etc. They've been very solid, I have no regrets. Their spam filtering has been a little hit and miss but other than that, solid.
Work email is moving from Google to https://www.infomaniak.com/en/ksuite/ksuite-pro - if you're not bothered about custom domains, they also offer an excellent free tier for personal use: https://www.infomaniak.com/en/ksuite/myksuite
Purchase a domain and point the MX record(s) to any provider you'd like. If you end up not liking that provider, you simply point the domain to a different one.
That's the main advantage of not using the provider's domain as a part of your email address (like @gmail.com, @outlook.com or whatever).
