Step-by-Step Setup in GoHighLevel
- Connect your phone system
Navigate to Settings → Phone. Connect LC Phone/Twilio as instructed. Verify your sender ID/number is SMS-capable. - Complete 10DLC registration
Provide brand details, use cases, sample messages, and opt-in description. Wait for approval and confirm throughput/limits. - Create consent-first lead capture
On your WordPress or GHL funnels, add a checkbox with explicit SMS consent language. Store consent fields (timestamp, IP, source) in contact custom fields. - Set global DNC and opt-out handling
In Settings → Compliance, enable automatic handling of STOP keywords. Add a workflow trigger “Customer Replied with STOP” → set DND: SMS = true. - Build reusable SMS templates
Go to Marketing → Templates → SMS. Create short, branded templates: lead welcome, appointment reminder, no-show follow-up, nurture, and reactivation. Keep under 160 characters when possible; put links last. - Create your core workflow
Automations → Create Workflow. Recommended structure:- Trigger: Form Submitted, Survey Completed, Appointment Booked, or Tag Added.
- Check: If DND:SMS = true → exit. If no consent → send email fallback or task.
- SMS: Use your template. Include opt-out hint (e.g., “Reply STOP to opt out”).
- Wait steps: Minutes/hours as appropriate; respect quiet hours with time windows.
- Branch: If replied → assign task to owner and stop further SMS. If no reply → send reminder or switch to email.
- Update fields: Last_SMS_Sent, Opt-in Source, Stage, or UTM fields for attribution.
- Add throttling and quiet hours
Use execution windows (e.g., 9am–7pm local time). Add delays for large batches to avoid spikes and carrier filtering. - Link tracking & landing pages
Use short, branded links. Point to fast pages (optimize hosting). Add UTM parameters to track conversions in analytics. - QA with a seed list
Test with your team across carriers (AT&T, Verizon, T-Mobile). Validate link rendering, opt-out behavior, and reply routing. - Launch gradually
Start with a small segment (e.g., 200–500 contacts) and monitor deliverability, reply rates, and blocks before scaling.
Proven SMS Workflow Examples
1) Double Opt-In (DOI)
- Trigger: Form Submitted with SMS checkbox checked.
- SMS: “Reply YES to confirm SMS updates from [Brand]. Msg&data rates may apply. Reply STOP to opt out.”
- If reply contains YES → set Consent = true; send welcome SMS; tag: sms_opted_in.
- If no reply in 24h → send reminder email; exit.
2) Lead Speed-to-Contact
- Trigger: New Lead via Ad/LP.
- Immediate SMS: “Hey {{first_name}}, it’s {{user.name}} from [Brand]. Want help with {{offer}}? Reply 1 for yes.”
- If reply 1 → notify owner; book call link.
- If no reply in 30m → send value snippet + CTA.
3) Appointment Reminders
- Trigger: Appointment Booked.
- T-24h SMS: Date/time/Location + “Reply C to confirm, R to reschedule.”
- If R → send reschedule link; update status.
- T-2h SMS: Short reminder + parking/zoom link.
4) Post-Call Nurture
- Trigger: Pipeline Stage = Demo Completed.
- SMS: “Great chatting, {{first_name}}! Here’s the case study: {{short_link}}. Questions?”
- Wait 2 days → SMS: “Want pricing options or a quick recap video?”
Deliverability, Filtering, and Message Quality
- Keep it short: Aim for one clear CTA. Use plain language and avoid spammy formatting.
- Brand up front: Include your brand in the first message and periodically thereafter.
- Segment smartly: Match message to lifecycle stage and recent engagement to lift reply rates.
- Throttle sends: Stagger large sends; respect carrier throughput guidance.
- Monitor blocks/bounces: Investigate sudden changes; adjust templates and cadence.
Analytics to Track and Optimize
- Delivery rate (by carrier and campaign)
- Reply rate and positive intent keywords
- Click rate on short links
- Conversion rate (bookings, purchases)
- Opt-out rate per message and per week
- Revenue per recipient for promo campaigns
Tip: Append UTMs to every link and attribute outcomes in your CRM/analytics. Automate weekly summaries with GoHighLevel workflows.
Alternatives and When to Use Them
- Email: Best for long-form and rich content; pair with SMS for confirmations and last-mile nudges.
- WhatsApp/OTT: Consider for international reach and richer media (follow platform terms).
- Voice/VM drops: Useful for high-intent follow-ups; use sparingly and with consent.
Evaluate channel mix against audience, region, and compliance requirements. Verify platform policies before adoption.
