Style Presets
halbert_letter
Personal, raw, conversational. Use for cold→warm or daily sender lists.
- Structure: Story or rant → Lesson/insight → Hard pivot into offer and CTA
- Short paragraphs, direct address ("you")
- Strong P.S. emphasizing urgency or scarcity
- No corporate jargon
bencivenga_proof
Polished, proof-heavy, authoritative. Use for mid-funnel or skeptical audiences.
- Structure: Unique mechanism / big idea → Stacked proof → Calm but powerful CTA
- Proof types to request: case study with numbers, named client results, mechanism demo, published research
- Specific numbers, details, and case snippets required — mark placeholders if missing
- Understated language, not shouty
sugarman_slide
Curiosity and story-driven. Use for cold traffic or content-heavy lists.
- Structure: Irresistible first line → Slippery-slide momentum → Reveal and offer
- Every sentence must make reading the next sentence feel inevitable
- Strong open loops, few hard section breaks
- Revelation is earned, not given upfront
ray_edwards_pastor
Framework-driven, compassionate. Use for faith-adjacent, coaching, or consulting audiences.
- Structure per email:
- P — Person / Problem
- A — Amplify consequences
- S — Story / Solution
- T — Transformation / Testimony
- O — Offer
- R — Response (CTA)
- Clear, warm tone. Often uses a personal story or client testimony in the middle.
- Explicit, direct CTA at the end.
frank_kern_results
Laid-back, results-in-advance. Use for warm lists or authority-building sequences.
- Structure: Give a real tactic → Show what result it creates → Soft invitation to next step
- Always includes one practical takeaway per email
- Casual, friendly — sounds like a smart friend, not a pitch machine
- CTA feels like "next logical step", never a hard push
Outputs

EMAIL [N] — [internal_name]

Sequence Timing Templates
Launch (5–7 emails)
- Email 1: Day 0 — Big announcement / story
- Email 2: Day 1 — Why this matters / problem agitation
- Email 3: Day 2 — Proof / case study
- Email 4: Day 3 — Objection crusher or mechanism reveal
- Email 5: Day 4 — Urgency / deadline reminder
- Email 6: Day 5 — Last call (morning)
- Email 7: Day 5 — Cart close (2 hours before)
Webinar Promo (4 emails)
- Email 1: Registration open / big promise
- Email 2: Day before — What they'll learn (specifics)
- Email 3: Day of — Reminder (morning)
- Email 4: 1 hour before — Final reminder + logistics
Post-Webinar (3 emails)
- Email 1: Same day — Replay + offer recap
- Email 2: Day 2 — Proof / FAQ
- Email 3: Day 3 — Last chance / cart close
Nurture (ongoing, weekly)
- Alternates: Value email → Soft pitch → Value email → Hard pitch
- Each value email delivers one actionable insight
Rules / Guardrails
- One primary CTA per email. Never stack two links with different destinations.
- Subject lines: Curiosity + clarity. No misleading clickbait. No all-caps gimmicks.
- Skimmable: Max 3 lines per paragraph. Use line breaks generously.
- Sequences tell a story. Each email advances the narrative — awareness → consideration → decision.
- No invented proof. Mark all placeholders:
[INSERT: client name, result, timeframe].
- P.S. is mandatory in halbert_letter style. Optional but recommended in others.
- Mobile-first. If a sentence runs past 12 words, consider breaking it.
