I have an Mxroute account. And I like them a lot. Very good people. But it’s a small scrappy operation that I don’t put in the same tier as a Fastmail or a Gmail. For its price, it doesn’t really need to be, but I’ve also had downtime (totally understandable), and it didn’t solve the ancillary problems of any accounts I’ve created with those Google Apps for Your Domain SAML/SSO. Which Google claims would/could still work, but would still require a lot of auditing on my part that I’m frankly happy to avoid.

Cloudflare’s email forwarding was also a consideration. I prefer having separate actual inboxes, but I could create new gmail or Outlook accounts to forward to. I may use that for a new family homelab project, where my husband doesn’t want to monitor a new inbox.
