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
