Steven Bartlett runs two newsletters, and neither is on stevenbartlett.com. Behind the Diary is his personal Sunday letter (“the things I’m thinking about at 2am”), with its own site and a button that reads “Join 450K subscribers”. The DOAC newsletter is the podcast’s, promising “episode drops, distilled frameworks, and the takeaways worth keeping”, and it is the only thing on thediaryofaceo.com.
The two sites are the same small app: one email field, Klaviyo behind it, a variant tag on every sign-up for A/B testing, and SparkLoop’s recommendation page between the form and the thank-you. Facebook ads from the “Steven Bartlett” page push Behind the Diary and a third promise, “Ask a CEO”, through instant forms that sign people up without leaving Facebook.
What was not captured: the instant forms (they only open inside the Facebook app), the newsletters SparkLoop recommends (behind a Cloudflare human check), and every email. Both newsletters were joined, but the inbox session had expired.
