Something that would be extremely helpful as a marketer would be the ability to know at what point a person became a customer in the followup process.
For example:
A person signs up for our sample material (List 1) and are emailed a series of follow-up emails as a result.
When they become a customer, they are signed up on another list (List 2), and signup-extra runs, removing them from list 1.
If, along with the notification that they have been signed up for the new list, we are also told the "cseq" they were on on the original list (List 1), we would be able to see what email in our follow-up process might have prompted them to make the purchase.
This would be EXTREMELY valuable information and would allow us to fine-tune our follow-up, and perhaps shorten our conversion time considerably!
This is one of those items that I know would only take a line or two of SQL to do, but I'm just not savvy enough write that SQL without possibly screwing things up.
If Dean can't implement this any time soon, perhaps someone else on the list can suggest the line of modified code for the admin.php file or signup-extra??
