I am ‘playing’ with a new plugin called Standout Comments.
At the moment there seems to be a bug if you subscribe to comments after commenting.
You receive the emails telling you there is a new comment but there is no unsubscribe link.
This is a right nuisance and I have stopped replying to some comments because I didn’t want to inundate your email inbox – especially as you cannot unsubscribe.
I am awaiting the Standout Comments support team to respond…meanwhile I am very sorry.
I will catch up once the bug has been resolved.
