The next phase of its campaign through Droga5 is based around the idea of pitting MailChimp against a "black hole" -- the black hole being a "metaphor for everything you don't know about your business." A series of videos first introduces the sinister black hole, then explains how MailChimp's tools can help it disappear by helping with marketing automation, better ROI reporting and finding new customers on Facebook and Instagram (seen here). Each video ends with the words: "Black hole bad. MailChimp good."
It's certainly memorable B2B advertising, even if it lacks the completely bonkers surreality of the branding campaign.
