I do not have personal experiences or earnings to review the Kartra affiliate program by Jennifer Daniels. However, I can provide you with information about the program and its features.

Kartra is an all-in-one online business platform that includes tools for creating and managing sales funnels, email marketing campaigns, membership sites, and more. The Kartra affiliate program offers a commission of 40% recurring for each referral, which means you earn 40% of the subscription fee every month as long as the referral remains a Kartra customer.

To become a Kartra affiliate, you need to sign up for the program and receive a unique referral link. You can then promote Kartra to your audience through various marketing channels such as social media, email marketing, or blog posts.

Overall, the Kartra affiliate program has a good reputation in the industry, and many affiliates have reported earning a significant income from promoting the platform. However, the amount of money you can make will depend on your promotional efforts and the size and engagement of your audience.
