For those of you not in the know, MailChimp is a really fun do-it-yourself email marketing service that lets you send email newsletters, manage subscriber lists and track campaigns. Last year, the developers over at MailChimp worked out a way to catch new data into their subscriber list automatically using Wufoo’s ability to serve secure RSS feeds of new entries. While [their approach](http://www.mailchimp.com/blog/wufoo-form-integration-with-mailchimp/) was a much better alternative to the older method of exporting data from Wufoo and importing the email addresses in bulk into MailChimp, it’s based on a system that has to periodically ask and check our servers to see if there was any new data in Wufoo.
Since our feeds only show the last 10 entries at any one time, if the polling is less frequent than the number of new entries collected in the interval, then the subscriber list could miss out on some new entries collected in Wufoo. Because we want to help make this process work better and more reliably between our users, we’ve stepped up our side of the game thanks to our new real time notifications to MailChimp.
Integrating your Wufoo form with MailChimp is now so much simpler. Just go to the [Notification Settings](https://help.wudev.com/articles/en_US/kb/Notifications/) for a form that’s collecting email addresses you want to add to a subscriber list and then follow along with Tim in this screencast:
With this new integration, you’ll be able to easily transition between collecting emails and contact information with Wufoo and getting in touch with those people in mass. This is all made possible thanks to our [integration platform](http://www.wufoo.com/2010/01/20/send-real-time-updates-from-wufoo-to-your-favorite-web-apps/), which lets you use our push system to instantly send new data to MailChimp as it comes in to your Wufoo form. This new integration comes with an intuitive field matching interface to associate any custom fields you’ve setup in MailChimp with data collected from your forms and the ability to only send these entries to MailChimp based on whether a user checks a checkbox on the form.
Please note that this integration **does not** allow you to export emails and entries that have already been collected through your form. It only works on entries after the integration is set up. Past entries would still need to be exported from Wufoo and then imported into MailChimp via CSV.
Integration with MailChimp is available to all users across all plans and so we hope you upgrade your integration method to our new system. Thanks go out to the brilliant monkeys over at MailChimp for hosting such a fine API. We’re really excited about this integration and hope you’ll enjoy the more seamless interaction.
