email-campaign
An intelligent email-marketing copywriting microservice. Every tool has a deterministic heuristic core that runs fully offline; the generative tools also try an optional LLM (via ../_shared/llm.js) and silently fall back to the heuristic. Results are tagged mode: 'heuristic' | 'llm'.
Tools
| Tool | Args | What it does |
|---|---|---|
subjectLines | { topic, audience?, tone?, count?, formulas?, seed? } | Subject-line variants generated by copy formulas (curiosity, urgency, benefit, question, how-to, number, personalized, FOMO, social-proof, negativity), ranked by open-rate score. Hybrid. |
previewText | { topic, tone? } | Inbox preview/preheader lines (40–90 chars) that complement the subject. Hybrid. |
spamScore | { text } | Deterministic deliverability check: spam-trigger-word list + ALL-CAPS/emoji/!/$/length heuristics → 0–100 spamScore + reasons + fix recommendation. |
abVariants | { subject, count?, seed? } | Spins a control subject into A/B/C… test variants (one lever each) and predicts a winner by score. |
ctaButtons | { goal?, topic?, count? } | High-converting CTA button labels by campaign goal (signup/sale/download/demo/webinar/reengage/nurture/waitlist). Hybrid. |
scoreSubject | { subject } | Scores + grades (A–F) a single subject line on length, personalization, question/number hooks, and spam risk. |
sequenceIdeas | { topic, goal?, steps? } | Outlines a multi-touch drip/nurture sequence with per-email purpose, send-day offset, suggested subject, and CTA. Hybrid. |
Example
import pack from './index.js';
await pack.adapters.subjectLines({ topic: 'our new analytics dashboard', tone: 'bold', count: 5 });
pack.adapters.spamScore({ text: 'FREE!!! Buy now and WIN CASH $#39; });
pack.adapters.scoreSubject({ subject: 'Your Q3 report is ready — 3 wins inside' });DRY boundaries
