There are literally dozens of requests asking to receive a notification/email when a user cancels a subscription:
How is this not yet a feature? It's basic in any membership.
Please, give us a notification or email when a user cancels a subscription, it's completely unpractical having to check this manually.
Some of us give extra content to subscribers like access to special posts, tweet, Instagram content, etc. and without this, we have to manually check the list of members every week.
I repeat: it's basic functionality on any membership system, not having this is like offering an incomplete product.
Please vote for this request so we can get this as soon as possible.
