ListMD is a MailChimp Labs app that gives you information on how your MailChimp lists are performing. It checks your lists every hour of every day to gather stats, so you can gain insight from your reports.
Here it goes:
MailChimp gives you most of this data per campaign—ListMD aggregates each campaign's data to generate a collection of stats per list.
ListMD takes one day from the time you activate to generate the first point of data. ListMD can't get historical data from MailChimp's API, so it will only show information about your list from the day you signed up.
We wish we could, but it would take a whole lot of floppy disks to store historical data for everyone's lists. We can't afford that many floppy disks, so we created ListMD. It starts storing your historical data the day you sign up.
If you have interest groups tracking the source of your subscribers, like "website," "iphone app," and "in-store," you can add those to ListMD, and we'll keep tabs on the groups in the same way that we look at the other metrics of your list.
