MailChimp 2012 Annual ReportMailchimp
The MailChimp annual report is presented in a brilliant One Page responsive site with tons of color and infographics!
This website has unfortunately redesigned or gone offline, so I have removed the link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this link on the Archive.org website. FYI: the site was first featured on 15 January 2013.
