Hi there @hamdictn,
With MailPoet, subscribers cannot subscribe directly to Post Notifications, or Post Notifications by category. They can only subscribe to *lists*.
So to set this up, you would need to:
- create a list that represents each blog category -> these would each need to be manually created, they are not dynamically created to match your categories
- create a form that includes the List Selection block, that allows people signing up to indicate which lists they want to be on
- under MailPoet > Emails, you’d create one recurring Post Notification email for each category; these emails would a) be set up to email the matching list, and b) pull items from the matching posts category
- like the lists, you’d need to manually create the Post Notification email that matches each list/category when you add a new one
In this way, subscribers can sign up to the content they want; your post notification emails will pull in new posts in the specific category and then send a notification to the matching list. Subscribers can use the Manage Subscriptions page to change the lists they are on (and thus adjust the blog post categories they are getting are getting notifications for).
If you want something more direct, you could consider Jetpack Newsletters instead, which allows you to insert email notification blocks that are directly tied to a blog post category. But this is also not quite dynamic, as you require a separate subscription block for each category and these must be manually added each time a new blog post category is added.
