GoHighLevel Missed Call Text Back — Complete Setup Guide (2026)

Why Missed Call Text Back Matters

Small businesses miss a large share of their inbound calls — lunch rushes, jobs in progress, after hours. Every one of those callers had enough intent to dial your number, and most won't leave a voicemail; they call the next result on Google. A missed-call text flips that: within seconds, the caller gets a message like "Sorry we missed you — how can we help?" and the lead stays alive as a text conversation you can answer between jobs.

For a plumber, dentist, or agency, saving even one or two of those callers per week typically pays for the entire GoHighLevel subscription many times over. (For the business case and ROI math, see our companion article on why missed call text back is the highest-ROI automation — this guide focuses on the GHL build itself.)

Prerequisites

• A GoHighLevel sub-account with a phone number purchased (Settings → Phone Numbers).
• For US numbers: completed A2P 10DLC registration, or your texts will be carrier-filtered.
• Call routing set up so business calls actually pass through GHL (forwarded number or GHL number as your main line).

Step 1 — Create the Workflow

Go to Automation → Workflows → Create Workflow → Start from Scratch. Name it "Missed Call Text Back".

Step 2 — Add the Trigger

Add the Call Status trigger and filter it to the statuses that mean nobody answered:

• No Answer — rang out
• Busy — line engaged
• Voicemail — went to your voicemail (include this; most callers hang up without leaving one)

If you use multiple numbers, add a filter for the specific number so internal calls don't trigger texts.

Step 3 — Add the SMS Action

Add Send SMS as the first action. Templates that consistently get replies:

• General: "Hi, this is [Business Name] — sorry we missed your call! How can we help? Reply here and we'll get right back to you."
• Trades/urgent: "Hi, it's [Business Name]. Sorry we missed you — if this is urgent, reply URGENT and we'll call you back first. Otherwise, tell us what you need and we'll reply ASAP."
• Clinics: "Hi, this is [Clinic Name] — sorry we missed your call! Want to book or reschedule an appointment? Reply here or book directly: [calendar link]"

Keep it under 160 characters where possible, identify your business by name, and end with a question — messages that ask something get far more replies than ones that just apologize.

Step 4 — Add Business-Hours Logic

Callers at 2am shouldn't get "we'll get right back to you." Add an If/Else branch on business hours before the SMS:

• During hours: the standard template above.
• After hours: "Hi, this is [Business Name] — thanks for calling! We're closed right now but we open at 8am. Reply with what you need and you'll be first in line tomorrow. Need to book? [calendar link]"

Step 5 — Notify Your Team

After the SMS action, add an Internal Notification (app push, SMS, or email to the owner/front desk) so a human follows up the moment they're free. The text-back buys you time — it doesn't close the job.

Step 6 — Test It

Publish the workflow, call your GHL number from a personal phone, let it ring out, and confirm: the SMS arrives within seconds, the contact is created in GHL, the conversation appears in the unified inbox, and your team notification fires. Test during and outside business hours to check both branches.

Advanced: Layer AI on Top

The basic build stops the bleeding. The advanced version converts:

• AI conversation bot: Connect the reply thread to a GHL Conversation AI bot (or a custom AI chatbot) that answers questions, qualifies, and books into your calendar automatically.
• AI voice callback: Instead of only texting, trigger an AI voice agent to call the person back within 60 seconds, answer questions, and book the appointment by voice.
• Follow-up sequence: If the caller doesn't reply within 30 minutes, send one gentle nudge; after 24 hours, a final message with your booking link. Two follow-ups roughly doubles recovered conversations.

Common Mistakes to Avoid

• Skipping A2P 10DLC registration (US) — your texts silently disappear into carrier filters.
• Triggering on ALL call statuses — completed calls get an awkward "sorry we missed you" text.
• No opt-out handling — keep GHL's default STOP handling enabled for compliance.
• Set-and-forget — check the conversation inbox daily; an answered text thread that then goes silent from your side is worse than no text at all.
