Constant Contact
Small business marketing made easy
Constant Contact is one of the most established email marketing platforms, particularly strong for small businesses and nonprofits. Its event marketing capabilities and social media integration set it apart, though its automation features lag behind newer competitors.
Keap
CRM-powered sales and marketing automation for small businesses
Keap (formerly Infusionsoft, founded 2001, acquired by Thryv in 2024) is a premium all-in-one CRM and marketing automation platform built for sales-driven small businesses that need contact management, email sequences, SMS marketing, invoicing, and appointment scheduling in a single tool. Its strength lies in powerful automation workflows and a dedicated Customer Success Manager, but the $299/month starting price for just 1,500 contacts makes it one of the most expensive options in its category.
