Campaign Monitor

Established email marketing platform known for design simplicity and agency-friendly tools, operating as part of Marigold's broader marketing technology portfolio

Campaign Monitor is an email marketing and automation platform that enables businesses of all sizes to design, send, and optimize email campaigns. Founded in 2004 in Sydney, Australia, the company built its reputation on delivering a beautifully simple user experience, making professional-grade email marketing accessible to designers, marketers, and agencies alike. Its drag-and-drop email builder, robust segmentation tools, and detailed analytics have made it a popular choice for tens of thousands of businesses worldwide. In 2014, Campaign Monitor received a significant $250 million investment led by Insight Venture Partners, which fueled international expansion and a series of acquisitions including Delivra, Tagga, and Conversio. The company was subsequently acquired by Marigold (formerly CM Group, which itself was a consolidation of several email marketing brands) and now operates as part of that broader marketing technology portfolio. Despite the ownership changes, Campaign Monitor continues to operate as a distinct brand and product offering within the Marigold ecosystem. Within the AdTech and MarTech landscape, Campaign Monitor occupies a strong position in the email marketing segment, particularly among small-to-mid-market businesses and creative agencies. Its emphasis on design quality, ease of use, and reliable deliverability differentiates it from more complex enterprise platforms. The platform competes with tools like Mailchimp, Klaviyo, and Constant Contact, and continues to serve a global customer base as part of Marigold's suite of marketing solutions.
