This might be a simple question but I really dont know. The easiest way to ask is to give an example. I have a local deals site. I post coupons for companies in our areas. When users wants to get any coupon they have to enter their email for access to that coupon. This will subscribe them to our master list and start a auto responder for that coupon that will start sending them reminder emails about using that specific coupon before it expires. (scarcity effect) Now here is my question. I want to use one single list since I own the deals site and want a master list of everyone who is getting coupons. But I need different auto responder for each coupon since each coupon deal has different details and information that needs to be sent out. If a user enters their email to get a coupon from company A they are added to our list and started on that coupons auto responder that reminds them to use that coupon. If a few days later a user wants to get another coupon from a different business they enter their email on that coupon...but here is the "problem". when setting up auto responders it seems that you select a list to add the user to. there are only a few options such as new subscriber, specific date, etc. If the new subscriber trigger is used they are already on the list from the previous coupon and so they wouldnt be added to this auto responder then would they? If any of the other triggers are used they are not based on when the user signs up. they are more just specific dates regardless of when the user sign up on the list. So the question is this: How can i have people get added/opted in to multiple unique and separate auto responder sequences yet still use the same master list they may already be on? ** I know i could set up a new list and a new auto responder for every single coupon but if i want to mail everyone that seems like it would be dumb since the majority of the exact same people could be on dozens of lists since this is a local deals site and not a wordwide thing.
