Overview
Constant Contact is an online marketing technology company and brand serving small businesses, nonprofits, associations, and other organizations. Its best-known service is an email marketing platform that enables customers to create campaigns, manage subscriber lists, distribute newsletters and promotional messages, and measure engagement. Over time, the brand expanded beyond email into event management, social-media monitoring, loyalty applications, digital storefront and local-business information services, marketing automation, customer relationship management, and broader multichannel campaign management. The business began in 1995 as Roving Software, founded by Randy Parker. Its early proposition was to make electronic communication and marketing tools accessible to organizations that lacked large marketing departments or specialized technical staff. The company adopted the Constant Contact name in 2004, making the brand increasingly associated with permission-based email communication and small-business marketing services. Constant Contact pursued an acquisition-led expansion during the late 2000s and early 2010s. In 2008 it acquired e2M Systems, an event-management platform for workshops, seminars, and conferences. In 2010 it acquired NutshellMail, which helped users monitor social-media accounts through email and complemented Constant Contact’s growing social-media capabilities. The 2011 acquisition of Bantam Live added a social customer-relationship-management orientation. In 2012, CardStar brought mobile loyalty functionality, while SinglePlatform added digital storefront and local-business information capabilities. In 2014 the company introduced Toolkit, an integrated marketing platform intended to bring email, social, mobile, and web activity into a broader campaign workflow. The product was presented as a way for smaller organizations to manage multiple campaign types while receiving real-time performance reporting. That year Constant Contact also launched a Small Business Innovation Program and hosted it at its InnoLoft facility in Waltham, Massachusetts, reflecting the company’s interest in supporting products aimed at small-business customers. Constant Contact was acquired by Endurance International Group in 2015 in a transaction valued at approximately $1.1 billion. After Endurance was acquired by Clearlake Capital in partnership with Siris Capital, Constant Contact was separated and operated as a standalone business. In 2021 it acquired SharpSpring, a marketing-automation and CRM provider, strengthening its capabilities for customers seeking more automated lead management and lifecycle marketing. In 2025 it acquired Moosend from Sitecore. Moosend continued operating its platform and also remained associated with Sitecore’s Send solution for relevant customers. The brand’s positioning centers on accessible, self-service marketing software rather than enterprise-only marketing infrastructure. Its offerings are designed to help organizations build an audience, communicate with contacts, promote events and products, automate follow-up activity, and evaluate results without assembling a large technical stack. The company has maintained offices or operations in the United States, Canada, the United Kingdom, and Australia. Its current portfolio reflects the convergence of email marketing, automation, CRM, social engagement, event promotion, and digital commerce within one small-business-oriented marketing brand.
History
Constant Contact originated in 1995 as Roving Software, founded by Randy Parker. The company was created around the idea that smaller organizations should be able to communicate with customers and supporters through digital channels without needing the resources of a large marketing department. Its core service became an online email marketing system, combining message creation, contact-list management, distribution, and campaign reporting in a hosted application. The company adopted the Constant Contact name in 2004. The rebranding emphasized continuity of communication and established the identity under which the business became widely known. During the following years, Constant Contact developed a strong association with small-business and nonprofit marketing. Rather than concentrating exclusively on sophisticated enterprise installations, it promoted tools that could be used by owners, administrators, and marketers with limited technical expertise. The company began expanding through acquisitions in 2008. Its first reported acquisition was e2M Systems, an event-management platform serving workshops, seminars, and conferences. This added event-related functionality to a business previously identified primarily with email. In 2010, Constant Contact acquired NutshellMail, a service that allowed users to monitor social-media activity through email. The acquisition supported the company’s broader effort to connect email with social engagement and was followed by additional social-media features, including reporting on how often campaigns and events were shared. In February 2011, Constant Contact acquired Bantam Live, a social CRM start-up. The transaction reflected the growing importance of contact management and relationship-oriented workflows within marketing software. In 2012, the company added CardStar, a mobile loyalty application, and SinglePlatform, a digital storefront and local-business information provider. SinglePlatform was reported at approximately $65 million and extended the company’s reach into local discovery, online business information, and digital promotion. Constant Contact’s product strategy became more explicitly multichannel in 2014 with the launch of Toolkit. The platform brought together email, social, mobile, and web marketing options, offered multiple campaign types, and provided real-time reporting intended to help customers evaluate performance. The company also introduced a Small Business Innovation Program, an accelerator for entrepreneurs and start-ups developing products and services for small businesses. The program operated from the company’s InnoLoft facility at its Waltham headquarters. A major ownership change occurred in November 2015, when Endurance International Group acquired Constant Contact for approximately $1.1 billion. The acquisition placed the brand within a broader online-services portfolio. After Endurance was acquired by Clearlake Capital in partnership with Siris Capital, Constant Contact was separated from the wider group and operated as a standalone business. In February 2021, Clearlake and Siris announced a $400 million joint investment associated with the spin-out. Constant Contact continued to expand its marketing-automation capabilities. In August 2021 it acquired SharpSpring, a provider of marketing automation and CRM software. This strengthened the brand’s ability to support lead nurturing, automated customer journeys, and customer relationship workflows. In June 2025 it acquired Moosend from Sitecore. Moosend, headquartered in Athens, Greece, brought additional email marketing and automation capabilities; it continued to operate its platform and also supported Sitecore’s Send solution for existing and new customers. The resulting brand is a marketing technology provider whose scope extends from email newsletters and promotional campaigns to automation, CRM, event marketing, social engagement, local-business promotion, and digital commerce. Its historical continuity lies in making online marketing accessible to smaller organizations, while its acquisitions have broadened the technology stack available to those customers.
