Keap

Keap is an all-in-one CRM and sales automation platform, rebranded in recent years from Infusionsoft. It combines email marketing, ecommerce capabilities, and workflow automation in a single system designed for small to mid-market service businesses and shops. The platform handles the full customer lifecycle from lead capture to repeat purchase.

Keap is strongest for service-based businesses and small ecommerce shops that want CRM, sales pipeline, and email in one tool. Unlike Klaviyo's email-first approach, Keap starts with CRM and adds email, making it a better fit for businesses that care as much about sales management and pipeline as marketing automation.
