I want to do this, but I don't want the hassle of running my own email server. Can someone recommend a good email hosting service for custom domains? Personal email, so needs to be fairly cheap.
You sign up with Google and follow a process they have, which involves setting some MX records and CNAME records on your custom domain to point to google's hosts.
This was free within some limits... I guess I assume it still is? (I set this up years ago. Google's never asked me for money for it.) I don't remember what the limits are. I and my family never hit them. I guess there are limits on the number of accounts and storage space.
I suppose since it's free it's a matter of time before they stop doing this, but so far so good.
