As someone who doesn't know much about MailChimp, the original question seems valid. A little more detailed answer (like the one by qeorge) would have helped me understand this better.

As you work at MailChimp, it would have helped if you would have given that detail.

Probably shoulda brought that up in my blog post (it's usually the first question techies ask), but it's something our customers are pretty familiar with, so I left it out.
