Leila, senior UX designer at a fintech company

I didn't think a book about upselling would change how I design a settings page. But here we are.

The chapter on the unsubscribe paradox stopped me mid-sentence. The author argues that a cancellation flow is a reverse diagnostic — the offers a company makes when a customer tries to leave reveal what the company thinks that customer is worth. I design cancellation flows. I'd never thought of them that way. I thought of them as retention tools, maybe as necessary friction. I hadn't considered that the sequence of screens a user walks through is, itself, a message about their value.

I redesigned a client's cancellation flow the following week. We replaced the single "Are you sure? Here's 20% off" screen with three options: pause, downgrade, or cancel. The pause option was the first thing the user saw. We framed the downgrade as "Find the plan that fits you better." The cancel button was clearly visible at every step. The client was nervous. Retention didn't drop. Pause uptake went up, and the support inbox had fewer angry emails about "why can't I just leave?"

The book also validated something I've felt intuitively for years: that interrupting a user during active work is worse than just not selling to them. The chapter on state of mind puts research behind that intuition. The concept of the satisfaction spike — offering the upgrade after the task is done, when the user is feeling competent — is now a principle I cite in design reviews. It has the pleasant property of being both ethical and effective. That's a rare combination in growth literature.

The book is long. Some chapters could be trimmed. But the thinking is solid, and the respect for the user's experience runs through every page. If you design digital products and you've been asked to "add more upsells," read this first. You'll have a better conversation with your product manager afterward.
