Constant Contact is one of the oldest email marketing platforms in the U.S. market, founded in 1995 and headquartered in Waltham, Massachusetts. It serves primarily small businesses, nonprofits, and event-driven organizations with email marketing, basic automation, event registration, and social media posting tools.
The platform offers three paid plans — Lite, Standard, and Premium — with pricing based on contact list size. The Lite plan starts at $12/month for up to 500 contacts. Standard starts at $35/month for 500 contacts and adds scheduling, A/B testing, segmentation, and up to three users. Premium starts at $80/month for 500 contacts and includes omnichannel capabilities, advanced segmentation, and unlimited users.
Prices scale sharply as contact lists grow — the Lite plan jumps from $12 to $50/month when moving from 500 to 1,000 contacts, a 317% increase. Annual prepay saves up to 15%. Nonprofits receive 20–30% discounts. Constant Contact removed its free plan in 2025, replacing it with a 30-day money-back guarantee.
The platform’s main strength is its event registration tools, which are integrated into Standard and Premium without requiring third-party tools. Phone support on Standard and Premium is rare in email marketing at this price point and valuable for non-technical teams.
The main weaknesses are pricing at scale and feature age. Costs increase aggressively with list growth compared to Mailchimp and Brevo. Most automation capabilities require Standard or Premium. Constant Contact is best suited to small businesses and nonprofits that need reliable email marketing, integrated event management, and phone support.
