WordPress notifies subscribes of new posts you publish on your WordPress site and you no longer want the subscribers to be notified? Here is how to stop it :
Add the code below directly to your theme’s functions.php file
add_filter( 'jetpack_allow_per_post_subscriptions', '__return_true' );
This will add a checkbox option to every new post of whether or not to email the post to subscribers.
So, when you want to publish new posts, ensure that you tick “don’t send this to subscribers”.
If you want to exclude certain categories from been emailed to subscribers you can check the codes to use here.
