MailChimp helps people send better email. And they support important things like Plywood People, Niice, CreativeMornings, and podcasts like Serial.
In 2013, I learned a lot as a writing intern in MC's DesignLab.
One of the development floors at MailChimp had a large empty corner with an ugly Coke refrigerator. The developers weren't feeling the love they're supposed to feel, so we turned the corner into a functional bodega, where employees can pick up magazines, snacks and drinks.
