I'm considering adding a custom taxonomy or two to my site, but I don't want to break my existing workflow with Postie. Does Postie support the setting of custom taxonomies in the subject line?
For example, my site deals with books and each post has a category for "age group" (Children's, Middle Grade, Young Adult, etc.) and a category for "genre" (Mystery, Thriller, Sci-Fi, etc.). Right now these are both set as categories, and I'm sending them in with a subject line like:
[Young Adult] [Sci-Fi] Awesome Book by Joe Author
This setup works great. But I'd like to expand my users' ability to search for books, and setting up a new taxonomy of "age group" and "genre" seems to make sense. So I'd love to be able to send in a subject line like:
[Age Group: Young Adult] [Genre: Sci-Fi] Awesome Book by Joe Author]
Is this possible?
