Here's what I need to accomplish:
Let's say list A is ALL customers (ones who signed up themselves)
List B and C are further refinements I have added to various List A customers for specific marketing purposes.
list B is customers designated for Monday
list C is customers designated for Tuesday
I want to send newsletter to only List C customers today, tomorrow list B, sometimes List A.
Is there a way within the existing 1.1.7 product to further separate the customers list? Is it possible to make a subcategory within the customer groups? or perhaps to add a customer to two categories? If I add extension for customer attributes will that help accomplish what I want?
Or do I just add all those customer groups as I wish upon approval, and then choose ALL the groups when I want to send to LIST A -a bit of a sledgehammer approach.
