Custom Post Notifications
Send new post notifications when you publish a custom post type. Limit new post notifications to specific categories, tags and custom terms
By default, Noptin only sends new blog post notifications when you publish a blog post. It does not allow you to send new post notifications for recipes, products, listings, events, or any other custom post type.
This addon changes that.
Not only that, but you can also limit the post notifications to certain categories, tags, and any custom taxonomies.
