ChimpKit is a complete Objective-C wrapper for the MailChimp API that connects your app to MailChimp, so you can automatically collect email addresses from within your own app. Then use MailChimp to keep in touch with your users and introduce them to all the great stuff you’re developing.

Want to try it out? We’ll give you six months of free, unlimited sending. It doesn’t matter how big your list is or how frequently you send — if you’ve got an app published on the app store, sign up and we’ll comp your account.
