Subscription Approval Notices enable the Owner/Moderator to approve/reject by email, or by direct link to that page of website.

However Pending Subscription' Membership Notice replies do NOT, which means the Owner/Moderator has to find the original Subscription Approval Notice, or go to the website and navigate to that page to approve or reject.

I suggest that replies to Pending Subscription' Membership Notices should also enable the Owner/Moderator to approve/reject by email, or by direct link to that page of website
