Founder, Thesis

"The Winback team deeply understands lifecycle marketing. They were able to take profiles that we considered dead and reactivate them. That's basically free revenue. This is a no brainer."

The Brand

Thesis is a subscription supplement brand that offers a personalized blend of nootropics to improve cognitive health. The brand experienced significant growth with endorsements from health leaders, including Dr. Andrew Huberman. They already ran a robust email program for active users and worked with Winback to increase revenue from their inactive users.

The Challenge

As acquisition grew, the team noticed that a large percentage of the emails they paid to acquire were dormant and no longer responding to email communications. To stay within best-practices and avoid damage to their reputation score, they did not target this audience, but they knew there was revenue to unlock in that list. They sought out a partner who understood how to maximize revenue generated from their dormant audience while improving their inbox placement and deliverability scoring. That’s where Winback came in.
