Constant Contact

One of the largest and most recognized email marketing platforms for small businesses and nonprofits, with a long-standing brand presence and broad SMB adoption.

Constant Contact is one of the pioneering email marketing platforms, founded in 1995 and headquartered in Waltham, Massachusetts. The company provides small businesses, nonprofits, and entrepreneurs with an accessible suite of digital marketing tools including email campaign creation, marketing automation, social media management, landing pages, and basic CRM capabilities. Its drag-and-drop editor, extensive template library, and list management features have made it a go-to solution for organizations without dedicated marketing teams. Constant Contact occupies a strong position in the SMB email marketing segment, competing directly with Mailchimp, Klaviyo, and HubSpot. The platform differentiates itself through ease of use, strong customer support, and a broad feature set that extends beyond email into event marketing, surveys, and e-commerce integrations. Its acquisition by Endurance International Group (later Clearlake Capital) and subsequent merger with SharpSpring in 2021 expanded its capabilities into marketing automation and CRM for agencies and SMBs. In the AdTech and MarTech ecosystem, Constant Contact serves as a critical last-mile marketing tool for millions of small businesses globally. The platform integrates with major e-commerce platforms, CRMs, and social networks, enabling cohesive multi-channel campaigns. With a subscriber base in the hundreds of thousands of businesses and a well-recognized brand, Constant Contact remains a significant player in the democratization of digital marketing for smaller organizations.
