After searching the forum and google I did not find anything close to an answer. I was wondering if it was possible to use the custom post type to send newsletters with the mailpress newsletter plugin.
I found this but it does not seams to be solved.
The idea would be to use a custom post type I created (promotions) and to enable user to get a mail each time a new "promotion" post is created.
I could use categories, create a "promotion" category it would work, that's my backupplan, but if it could work with my custom post type it would be great. It is less confusing I think for the enduser to create a "promotion" than to create a post and give it the promotion category.
Anyway if somebody got an idea it would be great ^^
