SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Building an SMS marketing program requires navigating TCPA consent rules, A2P 10DLC carrier registration, per-send cost economics, and sequence design — mistakes in any of these can mean filtered messages, wasted spend, or class-action lawsuits. This Skill provides the operational playbook to plan, write, and optimize SMS campaigns correctly from the start. ## Core Features & Use Cases - Compliance-first planning: Covers TCPA express written consent, A2P 10DLC registration, quiet hours, STOP/HELP handling, GDPR, and CASL with ready-to-use disclosure templates. - Sequence templates with copy: Provides full SMS copy with character counts and timing for welcome, abandoned cart, browse abandonment, post-purchase, win-back, replenishment, and promotional flows. - Platform selection guidance: Compares Klaviyo SMS, Postscript, Attentive, Twilio, Plivo, Brevo, and others by use case, pricing, and A2P support. - Use Case: A Shopify skincare brand with 80K email subscribers and no SMS program asks where to start — the Skill runs a compliance readiness check, recommends a platform, and ranks abandoned cart and replenishment flows by ROI. ## Quick Start Ask the assistant to design an abandoned cart SMS sequence for your store, including timing, copy with character counts, and compliance footers.

Frequently Asked Questions about sms

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write an abandoned cart SMS sequence?▼

Use a 3-message sequence: Send 1 at 30 minutes after abandonment with a gentle reminder and no discount, Send 2 at 4 hours with soft urgency, and Send 3 at 24 hours where a discount is allowed. Each message needs a sender ID, one CTA with a short link, and roughly 160 GSM-7 characters to stay in one segment.

Klaviyo SMS vs Postscript — which SMS platform should I choose?▼

Choose Klaviyo SMS if you already use Klaviyo for email and want one shared subscriber profile. Choose Postscript if you are on Shopify and want deeper SMS-specific features like AI Reply and advanced abandoned cart automations.

Can I send marketing SMS to customers who gave their phone number at checkout?▼

No. Checkout phone capture only covers transactional messages about that specific order. Marketing SMS requires TCPA express written consent with clear disclosure, frequency expectations, and STOP/HELP instructions captured with a timestamp.

Why are my SMS messages costing twice as much as expected?▼

Emojis, curly quotes, and accented characters force UCS-2 encoding, cutting the segment size from 160 to 70 characters and doubling billed segments. Preview segment count in your platform before scheduling and limit messages to one emoji.

What is A2P 10DLC registration and do I need it?▼

A2P 10DLC registration with The Campaign Registry is required for all US business SMS sent over 10-digit long codes since 2022. Without it, carriers throttle or filter your messages even if they show as delivered.

What is a healthy SMS opt-out rate per send?▼

A healthy opt-out rate is under 2% per send and under 0.5% for promotional sends. Rates above that signal over-sending or poor segmentation, and you should reduce frequency and segment by engagement level.
