Update update: This is really old, and nothing still applies here.
Update: A week later and MailChimp has fixed this by allowing you to turn off the chiclet feature… they are some fast chimps! So with that said this article will only apply to anyone who has left their privacy setting to “public”, which would most likely be any newsletter that already exists as of 4/1/11.
That turned out to be very easy since MailChimp uses two parameter variables to track everything: u and id. So to find those I just needed to either sign-up for their newsletter or, better yet, just find any MailChimp related links on their websites (like for the signup form or archives link) to find those parameters.
I love MailChimp and highly recommend them as they provide a really great service that is just plain fun to use. On top of that, the ability to start using them for free while your list is small (currently < 2000 subscribers) made it possible for me to start my newsletter. It does seem like they need to come up with a better way of doing this though, or at least let customers clearly know that their subscriber count is public.
Do you want to find out how many subscribers any MailChimp powered newsletter has? If so, forward one of their newsletters to email@example.com. I have a simple script that will process it and email you back the count and add it to this page. If they don't use MailChimp it will let you know that as well.
