Same prompt, same agent — the only difference is the skill.

Beforegeneric AI agent
SMS marketing can drive engagement and retention for subscription businesses. A welcome flow is a standard playbook—typically starting with a thank-you, then providing value, then promoting features or community. For a subscription box, you'd want to set expectations about shipping and delivery. How often do your boxes ship? Do you want to send SMS alerts for tracking, or is this more educational? What's your mobile opt-in rate? Those details shape the flow design.

WELCOME SMS FLOW: Subscription Box Onboarding

FLOW OVERVIEW
Auto-triggered on purchase completion. 5-message sequence over 10 days.

MESSAGE 1: Confirmation (sent immediately after purchase)
Text: 'Welcome to Flavor Box! Order confirmed. First box ships in 3-5 business days. Tracking info coming via SMS. Reply HELP for support.'
Goal: Set shipping expectation, build confidence
Metric: Confirm message delivery

MESSAGE 2: Offer Personalization (Day 1, ~9 AM user time)
Text: 'Flavor Box here! Customize your first box: choose spice level (mild/medium/hot) + dietary pref (vegan/keto/glutenfree). Link: clickable URL Expires in 24hrs.'
Goal: Drive engagement, reduce boxes returned unopened
Metric: Personalization link click-through rate (target 22%+)

MESSAGE 3: Social Proof (Day 3)
Text: '5,000+ subscribers have opened Flavor Box this month. See what they're unboxing: link to Instagram reel. Plus: your box arrives soon!'
Goal: Build community feeling, reduce new-customer anxiety
Metric: FOMO reduction, retention week-over-week

MESSAGE 4: Tracking (Day 6, when carrier updates available)
Text: 'Your Flavor Box is out for delivery today! Track it here: UPS tracking link. Excited for you to try it!'
Goal: Create anticipation, reduce support inquiries ('Where's my box?')
Metric: Tracking link clicks (40-50% typical)

MESSAGE 5: Delivery + Upsell (Day 8, post-delivery confirmation)
Text: 'Got your Flavor Box! Reply YES to tell us which flavors you loved (helps us pick next month). New customer? Use FLAVOR20 for 20% off renewal.'
Goal: Collect feedback, drive upsell, improve retention
Metric: Reply rate, renewal rate (target 65%+ for month 2)

COMPLIANCE & SETTINGS
→ Carrier: Twilio (SMS + MMS capable)
→ Opt-in method: Checkbox at checkout confirmed via double-opt-in
→ Unsubscribe: Cardholder receives link, STOP keyword respected
→ Frequency cap: Max 3 SMS per week during onboarding, then 1/week
→ Timing: Respect user timezone, avoid 9 PM-7 AM sends

EXPECTED PERFORMANCE
→ Delivery rate: 99%+
→ Open-equivalent (SMS read): 95%+ (SMS intrinsic)
→ Click rate (tracking/personalization links): 30-40%
→ Retention impact: SMS group typically 8-12% higher month-2 renewal

About this skill

Write text messages that are short, clearly from your brand, cost what you expect, and do not get filtered or put you at legal risk. Every message comes with its character count, encoding, and segment count.

What it does

  • Counts characters, encoding (GSM-7 vs Unicode), and billed segments, and catches emoji and curly quotes that triple the cost
  • Builds welcome, abandoned cart, browse, post-purchase, flash sale, and win-back flows with exits and caps
  • Includes sender ID, opt-in confirmation elements, STOP and HELP handling, and recipient-time-zone quiet hours
  • Flags TCPA consent, 10DLC or toll-free registration, carrier content rules, and branded links as items to verify
  • Audits an existing program and lists what is missing, without declaring it compliant

What you get

A flow table with every message counted, plus a compliance checklist to confirm with your SMS provider or counsel.

Best for

Ecommerce and subscription brands launching or cleaning up an SMS program.
