Kartra

Kartra packages checkout, email marketing, webinar hosting, and funnel building into one platform. You can design checkout flows with order bumps (additional offers shown after purchase), upsells, and downsells to increase average order value. The platform includes automation so you can trigger emails and follow-ups based on purchase behavior.

Kartra appeals to course creators who want to maximize revenue per customer through strategic upsells and email follow-up. It's built for marketers comfortable with funnel-building and A/B testing. The all-in-one approach cuts down on tool switching but comes with more complexity to set up.
