yes, I think that would be best.. at this point, I guess the only way that I can determine who has unsubscribed is to download the existing list on the server and compare to the original that I uploaded..
Also a really nice feature would be a universal remove option. I have multiple lists, but all on the same domain. So I need to opt them out of the domain and all mailings, more than just the individual list.
thanks
