Once a day could be acceptable. However is there a way to get information for only one of the lists instead of all of them?
For example, if I have a list for Product A and a list for Product B, is there a way to get subscriber information only for the Product B list?
Another possibility, If I have two lists List A and List B, could I have something setup to when someone subscribes to List A an auto-responder sends an email to people on List B but not to List A?
