A little while ago, we bought a set of stock icons for $50 or something. They were cool, and really spiffed up MailChimp. Until we noticed everyone else on the Interweb using the same icon set. Sigh. So later we bought a set for $199. Then we saw everyone using that set, too. Sigh.
For MailChimp v3, we went and got some custom icons done by the folks at the IconFactory. This is the same group that did the icons for Windows Vista, Coda (which I use every day) and who created Twitterific.
Here’s a sample of some of the custom icons they made for MailChimp:
If you’re a MailChimp user, you’re probably wondering what the heck a "smart folder" is. We use them on the new Campaigns screen, and the Reports screen. This video talks a little about them.
