I’ll have tags such as Art, Photography, Writing, etc. for my different genres of content. Also tags for different topics.
Would like a way for email subscribers to choose which tags they want to subscribe to. For example, someone interested in my art may have no interest in receiving posts with my writing or photography.
I think the best way to do this is to set up rules on your email pop-up/embed to show based on the url. This is assuming that your urls are structured based on the tags.
