Santa Monica, CA, New York, NY, and Waltham, MA – February 10, 2021 – Clearlake Capital Group, L.P. (together with its affiliates, “Clearlake”) and Siris Capital Group, LLC (“Siris”) announced today a $400 million growth equity investment by their affiliates in cloud-based digital marketing leader Constant Contact, Inc. (“Constant Contact” or the “Company”).

Headquartered in Waltham, Massachusetts, Constant Contact provides a cloud-based marketing platform that enables SMBs to create and track personalized marketing campaigns fueled by data-driven insights. A one-size fits all approach to marketing is ill-suited for today’s dynamic marketplaces particularly as businesses expand their digital footprints and transform the ways they interact with current and prospective customers. SMB marketers’ increasing reliance on highly personalized messaging delivered through digital channels has resulted in Constant Contact’s solutions being more relevant than ever. The Company’s software solutions facilitate the creation and distribution of professional-quality marketing emails to customers with easy-to-use drag and drop templates to improve customer engagement and help them drive better top-line performance in their own businesses. The comprehensive digital platform will continue to support and transform the ways that SMBs use data to boost their marketing efforts.


The Company boasts a long-standing, loyal customer base with over 470,000 subscribers that send approximately 7.5 billion emails per month as part of almost 2.5 million marketing campaigns. “Constant Contact is an important and trusted partner in my marketing strategy,” said Sonja Rasula, Founder & CEO of Unique Markets, a current Constant Contact customer. “I’m excited about their evolution and increased potential for growth, and what it will mean for the future of my business.”


“Constant Contact is one of the most well respected and recognized franchises in all of digital marketing and is poised to benefit from a number of significant growth drivers in the near-term,” said James Pade, Partner, of Clearlake. “We believe that this investment will provide the management team with significant resources to rapidly bolster the go-to-market organization and make large-scale investments in the product platform.”


“We are thrilled to partner with Constant Contact as the Company focuses on supporting modern-day marketers as they look to enhance key revenue generating activities,” said Tyler Sipprelle, Managing Director, of Siris.  “We look forward to working with the Company’s passionate team to extend the Company’s leadership position through both organic and inorganic growth initiatives.”
