Just wanted to let our customers know that we’re working on adding an image library to the MailChimp campaign builder. This will be a quick "v4.1.1" release that launches in the next few week-ishes. It’ll allow you to store all your images that you use for email campaigns into your own library, so you can re-use them later.
If we have time, we’ll add a MailChimpy spin to it. :-)
