I purchased the Klaviyo mastery course back in early 2021 and it made the company I work for almost $90,000 in 1 year. I then stumbled upon your customer lifecycle course and I was like I can't even imagine the returns this course is going to have for me. Overall it is has been a great experience and I owe it all to Andriy and his team
