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.
Mailjet
Collaborative email platform for teams with powerful API
Mailjet is a French-founded email platform (now owned by Sinch) that uniquely combines transactional and marketing email under one roof with real-time team collaboration. Its volume-based pricing with unlimited contacts makes it particularly cost-effective for businesses with large subscriber lists but moderate sending frequency. With strong GDPR compliance baked into its European DNA and a flexible API, it bridges the gap between developer-focused tools and marketer-friendly platforms.
