I've been on Zoho for my (and my partner's) email for 4+ years and it has been great. Chose them because there is no per-domain charge, so I have like 12 domains on it.

The configurability is extensive in both web app and ios email app. Service has been fast and stable. They rarely change anything in the UI (no random tinkering is what I mean) so it is predictable and easy to use.
