It's actually a question we get from MailChimp users just like you and with Call Loop we've made the easiest integration that allows you to do some really awesome things like this:
Literally with one-click, you can easily integrate MailChimp with Call Loop to start growing and building your own text message list
Set your own delivery date and time or immediately broadcast your message to your subscribers. Up to you and completely flexible.

Been using CallLoop for our text for the past 6 months or so. It's been really easy to use and I like the no monthly fee attached to it. Definitely worth checking out and testing since it's integrated w/ mailchimp now.
The only issue I for see is allowing recipients the ability to unsubscribe. Is this option available?
I have tried to use this integration with CallLoop.
So far I can not sync a list in MailChimp with Callloop and my efforts to get this resolved with their customer support has failed. Over 10 or so emails back and forth. No results.
Hope others have better luck
