Frameworks & Standards
| Framework | Application |
|---|---|
| Email Copywriting | Apply proven email structures: subject line → preview text → opening hook → value body → single CTA |
| Audience Segmentation | Tailor content blocks to subscriber segments (new, active, re-engagement) for relevance |
| Content Calendar | Align newsletter cadence to campaign timelines, product launches, and seasonal triggers |
| Hook Model | Design newsletters as a habit loop: internal trigger (curiosity/FOMO) → action (open) → variable reward (insight) → investment (reply/share) |

- Send Timing Recommendation
- Confidence Signal: 🟢 HIGH | 🟡 MEDIUM | 🔴 LOW
Maxim Behavioral Framing
Apply the Maxim MOAT to every output this skill produces:
Behavioral Science Layer:
- Primary framework:
composable-skills/frameworks/hook-model— newsletters are a recurring habit loop; the subject line is the trigger, the content is the variable reward, and the reply/click is the investment - Secondary framework:
composable-skills/frameworks/aida— body copy must move reader from interest to action before they scroll away - Apply Fogg Behavior Model (
composable-skills/frameworks/fogg-behavior-model): Motivation = subscriber pain point or curiosity addressed in subject line; Ability = short, scannable, mobile-optimized format; Prompt = subject line + preview text as the trigger event - Apply COM-B for re-engagement campaigns: Capability = easy one-click re-subscribe or preference update; Opportunity = personalized send timing; Motivation = exclusive or time-sensitive content
- Tag every output with confidence signal: 🟢 HIGH | 🟡 MEDIUM | 🔴 LOW
Framework Selection Logic: Newsletters are habitual consumption artifacts — readers must be trained to open every issue. The Hook Model governs the habit-formation arc across issues. AIDA governs the within-issue persuasion flow. Segmentation governs relevance, which is the primary driver of long-term retention.
Ethics Gate: Standard Maxim ethics apply. Never use dark patterns in subject lines (false urgency, misleading claims). All newsletters must include a visible unsubscribe mechanism per CAN-SPAM/GDPR requirements.
