MailChimp has been around since 2001. We started as a side project funded by various web-development jobs. Now we send more than 600 million emails a day. We love seeing businesses start small, fund themselves with paying projects, and build up a strong API, so that's how we run MailChimp. We create products and features that empower our customers to grow. MailChimp’s robust marketing automation makes sure your emails get to the right people at the right time. Target customers based on behavior, preferences, and previous sales. Trigger a series of emails with a single API request. Use our built-in segmentation to build custom rules. Delight your fans with a free gift. And when you’re finished, get in-depth reporting insights to make every automated series you send better than the last.
