Three types of customer lists. Use one CM list w/ Segments or 3 Lists?

I've got three types of lists,all for customers with the same "pain"

1. Product Line A inquiries (folks who download a trial of (or ask about) our PC software )
2. Subscribed to our new Web Based App
3..Subscribed to our Newsletter.

I am THINKING that we'd want to have them all in one list, but segmented and maybe with a Date that each of the above happened (Field for :  DateInquired  DateSubscriedWebApp  DateSuscribedNewsletter)  so that I could trigger AUTO-RESPONDERS

I don't forsee that we'll need to send the same message to any two of these groups. So maybe keeping them separate is a better idea.
It occurred to me that I might be able to rejoin them latter if needed:

But is there a better way to do this?
Are there advantages of doing these as three separate lists?

Hey MrAnalogy,

Great question! Generally, combining lists is better when you can, because that way you'll reduce your costs for any duplicated addresses (if you're on a monthly plan) and you'll also get better reporting because all campaigns will go to that one list (rather than having the reporting split up by list).

+1. Email subscription rates increase drastically when there is a preview of the email next to the sign up form. A thumbnail that can be clicked to see a full preview next to a sign up form and in an archive would help all of us send mrs Campaign Monitor email to more subscribers.
