Custom Domain Email Solution

I am ready to move our team onto a reliable, hosted email platform that runs on our own domain. A hosted service is a must—we do not want to manage servers in-house—yet I am still weighing which provider (Google Workspace, Microsoft 365, Zoho Mail, or another you can justify) will serve us best...
