Frequently Asked Questions
5 questions
ConvertKit can technically send emails to customers, but it lacks native SMS, advanced behavioral automation, and e-commerce integrations that Klaviyo provides. If your primary business is online retail with cart abandonment needs, Klaviyo is the better choice. ConvertKit excels when you're selling digital products (courses, ebooks) to creators.
