MailChimp has announced the release of the "intelligence API" that enables email marketers to sync campaign data to their customer database.

Along with customer data syncing, the API also:

• "Scrubs" lists, by withdrawing unsubscribe requests and bounced emails
• Links campaign stats to the database, enabling better targeting
• Sends campaigns based on purchase/signup date segments

The API, available in XML-RPC, PHP and JSON, will ideally encourage marketers to "outsource" their email marketing campaigns to the 'Chimps in toto.

Observe the API in action.
