Are there hooks for the subscribing / unsubribing action?
What I want to archieve is that when a user (un)subscribe then a email to the site admin should be sent.
The reason for this extension is that the site admin has a CRM and therefore is must be ensured that all changes the customer performed are always in sync with the crm.
Because the subscribers are syncronized with the crm. And if the site admin doesn’t know the customer has subscribed/unsubscribed then at the sync with the crm the changes will get lost.
Hopefully you could help me
