Thanks for getting back to me on this, it's been really helpful. I have now made the change and I can see the unsubscribe on my reports. I have just a couple of final questions if you could get back to me - and I would stop bothering-.
1) I can see the unsubscribe added on my reports but the count is giving me 0. I believe the formula to pull the data on the field is not correct? Could you shed some light on how should it be? I believe I should specify how many people clicked on the opt ou but I am not sure how to do that on the field (it would be easier if it was a query). Please see below:
Thanks a lot,
