Add custom email notifications for bbPress with this snippet:
function custom_bbpress_notifications( $email, $topic_id ) {
$subject = 'New Activity in Your bbPress Forum';
$message = 'There is new activity in the forum you are subscribed to.';
wp_mail( $email, $subject, $message );
}
add_action( 'bbp_new_reply', 'custom_bbpress_notifications', 10, 2 );
This will send email notifications to users when there is new activity in the forum.
