Mailchimp is a marketing automation and email marketing platform, operated by Rocket Science Group, a subsidiary of Intuit. Following its acquisition by Intuit in 2021, the platform has been branded as Intuit Mailchimp. The company was founded in 2001 by Ben Chestnut and Mark Armstrong, with Dan Kurzius later joining.2

How it started

History

Mailchimp was launched in 2001. The platform was named after one of their most popular e-greeting card characters, earning a few thousand dollars monthly. Mailchimp began as a paid service and added a freemium option in 2009. Within a year, its user base had grown from 85,000 to 450,000. By June 2014, it was sending over 10 billion emails per month on behalf of its users. As of 2020 more than 600 million emails are sent through the platform every two days.

In August 2017, it was reported that Mailchimp would be opening offices in Brooklyn and Oakland, California.

In February 2019, Mailchimp acquired LemonStand, a smaller competitor. Mailchimp later announced its plans to shift from mail distribution to offering a full marketing platform aimed at smaller organizations. This shift includes allowing customers to record and track customer leads within the platform, build landing pages and websites, and run ad retargeting advertisements on Facebook and Instagram. As part of this, Mailchimp acquired the London-based media and magazine company Courier Media in March 2020, with the stated goal of international growth. The magazine has a readership of 100,000 readers in more than 26 countries.

With founders Armstrong and Chestnut starting the company without outside funding or plans to go public, and never bringing on any outside investors thereafter, Mailchimp is considered an example of a successfully bootstrapped startup.
