In this short, Scott Perry explains that a publisher’s promise is distinct from a tagline or mission statement and must be a specific, believable, falsifiable, and consistently deliverable outcome for subscribers. He advises creators to define a promise that can be kept for each new subscriber, emphasizing that it should be testable (falsifiable), realistic (believable), and repeatable across publications. Perry warns against exaggerated, unachievable promises that sound like hype, and instead encourages a credible guarantee that bridges the gap between the reader’s current state and their desired outcome, ensuring the promise can be reliably delivered each time content is published.

What promise are you making? It's easy to confuse this question with the first question around the change that you seek to make. But the purpose of the promise question, the pro— what promise are you making, is it identifies a specific, believable, and achievable outcome that your business or your publication can deliver. This is not just your tagline. This is not just a mission statement. This is a promise you could keep for the next 100 people that you enroll as subscribers to your publication. What is the outcome that they can expect to get from you? What's the promise that you keep every time you publish an article on Substack, every time you publish a note? Some things that you can think about in terms of testing your promise is Is it falsifiable? Can someone demonstrate or articulate when you are not able to keep the promise? Is it believable? Is this an Alex Hormozi no-brainer promise where you're going to promise this outrageous, unachievable outcome or give them double their money back? That's not believable. It might help someone that's in a lot of pain buy your thing, but it's not a believable promise and it's not a promise that you can in good conscience know capable a majority of the time. So instead of hype, hype, what's the guarantee that you can make the credible bridge between where they are and where they want to be and how they can accomplish that by engaging with you and your publication and its promise? Is it something that you can keep consistently?
