I have registered an additional name just for use with CM.
So I have added an additional CNAME record as www -> cname.createsend.com.
I would also like CM to handle the site without the www's - is this possible?
Currently to do this, I would have to delete an A record, which points to my IP address.
It wouldn't be possible for us to handle that non-www domain for you I'm afraid. You can only have 1 custom domain per account, and the www. version is it. What you should be able to do, though, is set it up in your own DNS that the non-www version redirects to the www version.
Ok, thanks for the clarification Diana.
I realised shortly after posting that I could just set up a redirect using php if necessary.
Your are right Toby, a redirect of everyone from the domain.com to www.domain.com would be the way to go.
