Required: A summary of the newsletter edition's main topic or story (2–5 sentences); the newsletter's name and general tone (e.g. "analytical and dry", "warm and conversational", "urgent and activist") Optional: Your typical subscriber profile; any subject lines that have performed well or badly for you before; the sending day and time; whether you allow emoji in subject lines
Five numbered subject line options, each on its own line, followed by a parenthetical note explaining the technique. Total length: under 200 words. No preamble, no ranking. A single optional preview text suggestion (the 80–100 character line that appears after the subject in most clients) is appended at the end.
Newsletter name: The Friction Report Tone: Sharp, data-driven, slightly sardonic. Audience is product managers and UX professionals. Edition summary: This week's main story looks at new research showing that adding a progress bar to checkout flows actually increases cart abandonment in one specific product category — subscription boxes — by 14%. The finding contradicts years of UX conventional wisdom. We also cover three other studies from the same research group. Emoji: No. Previous high-performer: "The UX rule everyone is breaking (correctly)"
The progress bar that kills conversions (Direct value: names the specific element and the outcome — no ambiguity about what the reader gets)
Everything you know about checkout UX is wrong (Contrarian: challenges a widely held belief without being clickbait — the edition delivers the proof)
Why your progress bar might be costing you subscribers (Personal relevance: "your" makes it immediately applicable to the reader's own product)
New data: progress bars hurt subscription box checkouts (Credibility-forward: leads with "new data" for readers who respond to evidence over intrigue)
The 14% problem hiding in your checkout flow (Curiosity gap + specificity: the precise number creates intrigue; "hiding" implies something discoverable)
Preview text suggestion: New research from 4,200 checkouts — and why the fix isn't what you'd expect. (87 characters)
