Original Title: Question about iMessage
Well, let's start with what device you're on, since that's kind of key to finding the path forwards.
Generally, when you sign in with your iCloud account, anyone can send an iMessage to your email address and it should just work.
If it's not working, we kind of need to know what does happen - what error messages (if any) the sender gets, whether you can send messages, how the recipient sees them (e.g. from your phone number? your iCloud address? something else?)
So there isn't a single magic wand answer to this. Need more details on what is (and is not) working first.
