In that case I’d still suggest the single “email” datatype, with fields for ‘Seen’ (of type list of Users), Reference Number (this could just point back to the original email, if that’s what you’re looking to do), etc. Depending on how you approach the ‘Bookmark’, this may be better as a list of ‘Emails’ on the User datatype (or a related satellite datatype, which when scaling / increasing the number of emails bookmarked, would be better for performance).
