A Magic Pages customer recently asked about the possibility of hiding certain HTML content in emails, based on members' tiers:

The Ghost team (and Ghost power user and contributor Cathy) quickly confirmed that a feature like this is on its way, and currently in beta.
Since beta features in Ghost always need to be manually enabled, using this will need some manual intervention from my side. If you are interested in using this beta feature on a Ghost site hosted on Magic Pages, please reach out to help@magicpages.co or by using the live chat. I will happily enable the necessary configuration for you.
