Marketing Skills v2.1.0

A new skill drop — adding sms for SMS/MMS marketing, plus five platform integration docs to support it.

Total skills: 41

New skill: sms

SMS/MMS marketing built for B2C ecom and DTC, mobile apps, and B2B SaaS doing transactional/auth messaging. Compliance-forward from day one because the legal exposure (TCPA, A2P 10DLC, GDPR, CASL) is real and easy to get wrong.

What's inside

• SKILL.md — strategy, when SMS beats email, compliance overview, sequence types, copy guidelines (character counts, GSM-7 vs UCS-2, segment economics), platform selection, measurement, common mistakes
• references/compliance.md — TCPA, A2P 10DLC registration, EU GDPR, CASL, Australia Spam Act, opt-in disclosure templates, STOP/HELP response templates, audit-ready checklist
• references/sequence-templates.md — full copy templates with character counts for welcome, abandoned cart (30 min / 4 hr / 24 hr), browse abandonment, post-purchase, win-back, promotional, transactional, re-engagement, replenishment, VIP
• references/platforms.md — platform deep-dives across Klaviyo SMS, Postscript, Attentive, Twilio, Plivo, AudienceTap, Brevo, SimpleTexting, Customer.io
• evals/evals.json — 6 eval cases covering getting started, abandoned cart sequence design, TCPA compliance, opt-out diagnosis, A2P throughput, and emoji segment cost

Key principles surfaced

• Compliance is the foundation, not an afterthought — every send must justify itself
• Every send has a real cost ($0.0075–$0.04 per message + carrier fees) — forces relevance
• Brevity + clarity — 160 GSM-7 chars per segment, emojis force UCS-2 (70 chars / segment, doubles cost)
• A2P 10DLC registration is non-negotiable for US 10DLC traffic since 2022 — unregistered sends get throttled or filtered
• One CTA, one short link per message — UTM-tagged for attribution

New tool integrations

• tools/integrations/twilio.md — programmable SMS API, dev-first, full control
• tools/integrations/postscript.md — Shopify-native DTC SMS, deepest Shopify integration
• tools/integrations/attentive.md — mid-market+ DTC SMS with concierge support
• tools/integrations/plivo.md — Twilio alternative at ~20–30% lower per-send cost
• tools/integrations/audiencetap.md — newer DTC platform with AI-forward creative + on-pack QR opt-in
