There is a bug in this extension which sends even the approval queue posts by email to the normal users who have checked to get all posts in the tags they follow. So datitisev will kindly fix this in a few days for this extension and add a new option to send email for approval queue posts to admins and mods in the Subscribed extension. Also he will fix sending full text of new discussion posts not going in this, Subscribed, and Pretty Mail extensions. I can confirm that the full texts of reply posts are coming now in the Pretty Mail extension also, just like in the default non-html Flarum mention emails. For new discussions, full text is not coming yet in any of the extensions. Thanks datitisev for your kind help.
