Hi @wpac,
Yes, it is possible to limit subscriptions to a specific post category. You can use the jetpack_subscriptions_exclude_all_categories_except filter to achieve this. Here’s an example code snippet that only sends subscription emails for posts belonging to the “VaultPress” or “Akismet” categories:
function jetpackme_exclude_all_posts_subscriptions_except( $categories ) {
$categories = array( 'vaultpress', 'akismet');
return $categories;
}
add_filter( 'jetpack_subscriptions_exclude_all_categories_except', 'jetpackme_exclude_all_posts_subscriptions_except' );
Replace ‘vaultpress’ and ‘akismet’ with the desired category slugs.
