In this 2025 setup guide, you’ll wire a consent-first SMS system in GoHighLevel with templates, triggers, reminders, and recovery loops—without bloating WordPress or breaking compliance.

Try GoHighLevel — SMS, email, calendars, funnels, and CRM in one stack.

GoHighLevel SMS Marketing Automation Setup: What You’ll Build

You’ll implement a modular SMS system that:

  • Captures explicit SMS consent at the first touch and stores it on the contact record.
  • Triggers timely, relevant SMS messages based on forms, bookings, and pipeline stages.
  • Boosts show rates with a proven 24h/3h/15m reminder cadence and no-show recovery.
  • Protects deliverability with quiet hours, throttling, and opt-out handling.
  • Tracks performance with clear attribution and outcome metrics.

Pre-reqs: Working calendars, forms with hidden UTM fields, and a clean WordPress embed strategy. See GHL Automation Patterns (2025) and Calendar Booking Setup.

Consent-First Architecture and Compliance Basics

SMS compliance varies by region. Always obtain explicit consent, honor opt-outs, and follow local laws. The following is general best practice—not legal advice.

  1. Capture explicit SMS consent:
    • Add a consent checkbox to lead forms (unchecked by default). Example: “I agree to receive SMS messages about my inquiry. Reply STOP to opt out.”
    • Map consent to a boolean field (e.g., sms_consent) on the contact.
  2. Honor opt-out automatically:
    • Enable keyword handling (STOP, CANCEL, UNSUBSCRIBE) and map to DND/SMS opt-out.
    • Gate every SMS action with a consent + DND check.
  3. Quiet hours and frequency caps:
    • Implement regional quiet hours (e.g., 8am–8pm local time) to reduce complaints.
    • Rate-limit nurture flows (e.g., no more than 3 SMS/week per contact).
  4. Identify your brand clearly:
    • Use short, branded copy. Include an opt-out note on first touch: “- Brand. Reply STOP to opt out.”

Core GoHighLevel Settings to Configure

  • Phone number & sending profile: Provision a number, set area code strategy (local presence if relevant), and verify sender ID.
  • Custom fields & tags: sms_consent (boolean), country, timezone, last_sms_sent_at, tags like Engaged: SMS.
  • Opt-in templates: Draft welcome/confirmation SMS with brand and opt-out language.
  • Keyword automations: Create keyword-based triggers for STOP/HELP and support flows.
  • Quiet hours logic: Add workflow conditionals on contact timezone before send.

5 High-Impact SMS Workflows to Ship First

1) Speed-to-Lead SMS + Email Combo

Trigger: Form Submitted (Lead) → Filters: sms_consent = true, not existing customer, not DND.
Actions: Assign owner → Send email confirmation → Send SMS within 2–5 minutes → Create task “Call in 5 minutes.”
Copy tip: “Hey {{first_name}}, got your request. Quick 15-min call to help? Book here: {{calendar_link}} – {{brand}}. Reply STOP to opt out.”

2) Lead-to-Booking Nurture

Trigger: Tag Added = Lead: Warm OR page view: pricing.
Branch: If no booking in 24h → send SMS nudge; else → exit.
Copy tip: “Still interested? Slots opened this week: {{calendar_link}}. — {{brand}} (Reply STOP to opt out)”

3) Show-Up Maximizer (Reminder Cadence)

Trigger: Appointment Booked.
Actions: Email reminder at 24h → SMS at 3h → SMS at 15m with join/reschedule links.
Post-event: If Attended → send recap + next steps. If No-Show → move to Recovery flow.

4) No-Show Recovery

Trigger: Appointment Status: No-Show.
Actions: SMS with instant reschedule link → Create task for owner → Follow-up email next morning.

5) Dormant Lead Re-Engagement

Trigger: Last Activity > 45 days, Stage in Lead/Contacted, consent true.
Actions: “Still relevant?” SMS with two quick-reply options (e.g., Yes/Not now). Tag replies and branch accordingly.

Copy Frameworks that Convert (and Stay Friendly)

  • Be short and outcome-driven: One idea per message, one CTA.
  • Lead with value: Agenda, benefit, or new slot availability.
  • Personalize smartly: Use {{first_name}}, relevant service, or last action.
  • Always provide an exit: “Reply STOP to opt out.”

Examples you can adapt:

  • “Hi {{first_name}}, it’s {{owner_first}} from {{brand}}. Want a quick 10-min audit? Book: {{calendar_link}}. Reply STOP to opt out.”
  • “Reminder: {{appt_date}} {{appt_time}}. Need to reschedule? {{reschedule_link}} – {{brand}}. Reply STOP to opt out.”
  • “Missed you earlier—no worries. Grab a better time here: {{calendar_link}}. — {{brand}}. Reply STOP to opt out.”

Step-by-Step Build: Your First Consent-Gated SMS Flow

  1. Create fields: Settings → Custom Fields: sms_consent (checkbox), timezone (auto or select), last_sms_sent_at (date/time).
  2. Update your form: Add consent checkbox with clear language. Map to sms_consent. Add hidden UTM fields (source, medium, campaign).
  3. Draft templates: Create SMS templates for welcome, booking nudge, reminders, and no-show recovery.
  4. Build the workflow:
    • Trigger: Form Submitted = Lead Intake
    • Filters: If sms_consent=true AND not DND
    • Action order: Assign Owner → Email confirmation → Wait 2–5 minutes → If within quiet hours → Send SMS welcome with calendar link → Create task for owner
    • Fail-safes: If owner unassigned after 5 minutes → Notify ops via email/Slack/webhook
  5. QA test: Submit a test lead with a real phone number. Confirm fields, messages, and tasks fire correctly. Validate opt-out handling with STOP.

Keep WordPress light: embed forms/calendars via native HTML blocks and avoid heavy plugins. See WordPress integration playbook.

Deliverability, Throttling, and Quiet Hours

  • Quiet hours: Add a conditional “Local time between 08:00–20:00?” before any send. If not, delay until morning.
  • Throttle volume: For large sends, batch by tags or segments to avoid spikes.
  • First-message etiquette: Identify your brand, purpose, and opt-out. Keep within 160 characters where possible.

Analytics and KPIs to Track

  • Speed-to-first-response: Median minutes from lead submit to first SMS/email.
  • Booking rate: Percent of leads who book within 7 days.
  • Show rate: Attended / Booked after reminder flow.
  • No-show recovery rate: Percent of no-shows who rebook within 7 days.
  • Unsubscribe rate: Opt-outs per 100 SMS—use this as a quality signal.

Pro tip: Persist UTMs to contact fields and track conversions on thank-you pages for clean attribution across SMS + email + pages. See our automation guide for attribution patterns.

When to Extend with Third-Party Tools

  • Advanced routing/logic: Use Make/Zapier/n8n for complex enrichment or round-robin rules.
  • Omnichannel: Add email, voice drops, or chat where relevant—but keep SMS purposeful.
  • Bulk campaigns: Segment tightly and throttle; avoid broadcast fatigue.

Deployment Checklist (15-Minute Go-Live)

  • Consent checkbox maps to sms_consent; STOP/HELP keywords work and set DND.
  • Owner assignment and fallback alerts configured.
  • Quiet hours conditionals in place; test time zone behavior.
  • Templates include brand + opt-out on first message.
  • UTMs captured and conversion fires on thank-you pages.
  • Tasks created where humans must act (and are assigned).

Final Recommendations

  • Start with 3 workflows: Speed-to-Lead, Show-Up Maximizer, No-Show Recovery.
  • Audit weekly: Unsub rate, quiet hours, delivery errors, and copy freshness.
  • Iterate lightly: One change per week: timing, copy, or segmentation.
