Why post here about issues Apple says you are having with Bluehost. I suggest you talk to them. While you are talking you might want to address these other identified issues with your website that I found while identifying your host, or at least their name servers. See https://intodns.com/grantmaclaren.com I would not be surprised if this is all a SPAM email you are receiving. AS I assume the domain owner you get to add and remove email addresses from the hosted platform. Unless you have someone you hired to manage the domain for you. A BlueHost reseller perhaps. If that is the case you need to be talking to them not bluehost.
