About

SMB email marketing platform with automated sequences and social media tools; veteran small business marketing solution competing with Mailchimp for non-technical business owner customers.
About
Constant Contact is an email marketing and digital marketing platform for small businesses — providing email newsletter creation, automated email sequences, social media management, event marketing, and online store promotions for entrepreneurs, nonprofits, and small organizations. Founded in 1995 in Waltham, Massachusetts, Constant Contact was one of the first email marketing platforms for small businesses and has served millions of SMB customers. The company was acquired by Endurance International Group and later by Clearlake Capital Group and renamed Newfold Digital; Constant Contact has operated as an independent brand.\n\nConstant Contact's platform provides drag-and-drop email template builders, contact list management, automated email sequences (welcome series, birthday emails, abandoned cart reminders for e-commerce), social media post scheduling, landing pages, and event registration management. The platform targets non-technical business owners who need marketing tools without requiring marketing expertise — the interface emphasizes simplicity and guided campaign creation.\n\nIn 2025, Constant Contact competes with Mailchimp (the dominant SMB email platform), Brevo (formerly Sendinblue), and HubSpot's free email tools for small business marketing software. The SMB email marketing market has seen significant competition from freemium-first competitors that offer generous free tiers to acquire customers. Constant Contact's traditional subscription model has faced pressure from Mailchimp's free-up-to-2,000-contacts tier. The 2025 strategy focuses on adding AI-powered marketing tools (AI email subject line and content generation), expanding marketing automation capabilities to compete with more sophisticated platforms, and maintaining its loyal SMB customer base through strong customer support and educational content.
