A: You could do that by creating some content - let's say an entry with fields like (subject, rich text content, category)
And then with your app where you decide to send out an email - you could for example see for which category this user fits, and the pull (using our GRAPHQL API) the relevant content - and generate an HTML body that embeds this content inside of it.
