GoHighLevel missed call text back is the automation I build first in every new sub-account, before pipelines, before calendars, before anything with AI in the name. It is the only workflow that rescues revenue you have already paid to generate. Every missed call from a Google Business Profile listing or a paid ad is a lead you funded and then dropped.

In this guide I will walk through the exact build I use for Australian trades, clinics and service businesses: the Call Status trigger, the wait step, the business-hours conditions, the Conversation AI handoff, and the tagging and pipeline updates that make it measurable. I will also cover compliance properly, because Australian SMS under the Spam Act is not the same as US sending under A2P 10DLC.

Why missed calls cost you real money

A missed-call workflow does one thing: when a call to your GHL tracking number goes unanswered, the system texts the caller within seconds — something like "Sorry we missed you — we're with a customer. Reply here and we'll sort you out." Instead of ringing your competitor, the caller replies, and now you have a conversation on your terms.

Treat the popular statistics with care — claims like "62% of calls to small businesses go unanswered" are directional at best, since the underlying studies vary in method and sample. What I see auditing Australian sub-accounts is more useful: a typical single-operator trade business misses 20–40% of inbound calls during work hours, and close to 100% after hours. Your GHL call reporting will confirm it within a fortnight of installing a tracking number.

Why texting back beats voicemail

Voicemail asks the caller to do work. A text puts the next step in their hand: they can reply from traffic or a job site. In the sub-accounts I manage, reply rates to a well-timed missed-call SMS routinely sit between 30% and 50% — no voicemail greeting achieves that. In agency communities the same build is called HighLevel missed call text back; it is not a separate feature.

Exact setup in GoHighLevel

Step 1: Get a phone number that can receive calls

Go to Settings → Phone Numbers and purchase a LeadConnector number (GHL's native telephony, built on Twilio infrastructure), or connect your own Twilio account for direct billing. For Australian clients, buy a local number with SMS capability — not all AU numbers support two-way SMS, so check the capability icons before purchasing. Forward the number to the client's real mobile or landline so calls still ring a human first; the automation only matters when nobody picks up.

Step 2: Build the workflow with the Call Status trigger

Create a new workflow in Automation → Workflows and add the Call Status trigger. Set the filter to Call status is: missed. You may also want to include "voicemail" and "no answer" statuses — test with real calls, because carriers report statuses slightly differently. GoHighLevel's documentation at help.gohighlevel.com lists which statuses each number type reports.

Step 3: Add a short wait step

Insert a Wait step of 30 to 60 seconds before the SMS. It lets the caller leave a voicemail without their phone buzzing mid-message, and stops the text landing while the owner is already calling them back. The difference between "helpful" and "spammy" is often 45 seconds.

Step 4: Write the SMS with custom values

Add an SMS action. Use custom values so the same workflow snapshot deploys across clients without editing: {{location.name}} for the business name, and a custom value like {{custom_values.booking_link}} for the calendar URL. Keep it under 160 characters where possible so it sends as a single segment, which matters for cost and deliverability.

Step 5: Branch on business hours

Add an If/Else condition on the current time, or split into two workflows using the workflow's time-window settings. During business hours, the message says "we're with a customer, reply here." After hours, it should say "we're closed, here's the booking link, we'll confirm first thing." Sending the daytime message at 11pm reads as careless.

Step 6: Hand replies to Conversation AI

The text back is only half the build. When the caller replies, someone has to respond — and if that someone is a plumber under a sink, the lead dies again. Configure Conversation AI in suggestive or auto-pilot mode, scoped to answer service questions and push toward a booking. My Conversation AI setup guide covers the full build; the short version: give the bot the services list, the service area, and one goal — book the appointment.

Step 7: Tag, track and update the pipeline

Finish with an Add Tag action (I use missed-call-textback) and a Create/Update Opportunity action that drops the contact into a "Missed Call – Contacted" stage. Without this you cannot measure anything. If your stages are a mess, fix that first — my guide to pipelines and opportunities in GoHighLevel covers the structure I use. You can also stamp a custom field like last_missed_call_date for reporting.

SMS compliance for Australian and US senders

Australia: the Spam Act and ACMA

In Australia, commercial SMS falls under the Spam Act 2003, enforced by the Australian Communications and Media Authority. A text back to someone who just called you rests on solid ground, because the call constitutes inferred consent for a directly related response. Two obligations still apply: identify the sender (use the business name in the message body), and give any ongoing marketing messages a functional unsubscribe. GHL handles "Reply STOP to opt out" automatically when you enable SMS compliance settings at the location level — turn it on. ACMA has fined businesses heavily for SMS breaches in recent years; current guidance lives at acma.gov.au. One trap: alphanumeric sender IDs cannot receive replies, defeating the purpose of this automation — use a standard mobile-format long code, and note ACMA's SMS sender ID register now covers brand-name sender IDs.

United States: A2P 10DLC registration

If you or your clients send to US numbers, none of this works until the number is registered for A2P 10DLC. Unregistered traffic gets filtered by US carriers — your texts simply vanish. Registration runs through your LeadConnector or Twilio settings and requires brand and campaign approval, which can take days. I have documented the process and the common rejection reasons in my A2P 10DLC registration guide. Australian-to-Australian traffic does not require 10DLC — the Spam Act is the local equivalent, and it has teeth.

SMS templates that convert

Copy matters more than most builders admit. The message must sound like a human at the business, not a platform. Four scripts I deploy:

1. The standard business-hours reply

"Hi, it's {{location.name}} — sorry we missed your call, we're on the tools with another customer. What can we help with? Reply here and we'll get straight back to you."

2. The after-hours booking push

"Hi, you've reached {{location.name}} after hours. We'll call you first thing tomorrow — or grab a time that suits you here: {{custom_values.booking_link}}. Reply STOP to opt out."

3. The urgent-trade variant

"{{location.name}} here — sorry we missed you. If it's urgent (burst pipe, no power), reply URGENT and we'll ring you back within 15 minutes. Otherwise reply with a few details and we'll sort a time."

4. The clinic/appointment variant

"Hi, it's the team at {{location.name}}. Sorry we couldn't get to the phone. If you're after an appointment, book directly here: {{custom_values.booking_link}} — or reply and reception will text you back."

These share three traits: sender identified, a reason for the miss, one next step. Never stack two links or two questions in the first message.

Measuring ROI

The maths is deliberately simple: calls missed per week × recovery rate × average job value × 4.3 weeks = monthly revenue recovered. A conservative example: an electrician misses 8 calls a week, 40% reply to the text, and the business closes half of those replies — a 20% overall recovery rate. That is 1.6 jobs a week at $450 average, roughly $3,100 a month recovered from calls that previously went nowhere, against a platform cost of $97–$297.

Track actuals with the missed-call-textback tag and the step 7 pipeline stage: count tagged opportunities that reached "won" and multiply by real job values. Report it monthly — it is the easiest retention lever an agency has.

Advanced variations

After-hours flows with next-morning follow-up

Extend the after-hours branch with a wait-until step that fires at 8:05am the next business day: "Morning — following up on your call last night. Still need a hand?" This second touch recovers callers who fell asleep on your first message.

Booking-link replies instead of open conversation

For appointment-based businesses, skip the chat entirely and send the calendar link in the first message. It only works if the calendar is configured properly — availability, buffers, confirmations — because a booking link showing no availability is worse than no link at all.

Voice AI answering instead of missing the call

The 2026-era option is to stop missing calls altogether: GHL's Voice AI answers as a receptionist, qualifies the caller and books the appointment in real time, with missed call text back retained as the fallback for callers who hang up on the bot. I deploy both — Voice AI first, text back as the safety net — though for most sub-$500/month clients text back alone is the right start.

Common mistakes to avoid

• No wait step. The SMS lands while the caller is mid-voicemail or while the owner is calling them back. Always wait 30–60 seconds.
• Texting from a number that can't receive replies. Alphanumeric sender IDs and some AU number types are one-way. Test two-way SMS before going live.
• One message for all hours. "We're with a customer" at midnight erodes trust. Branch on business hours.
• No reply handling. A 40% reply rate is worthless if nobody answers for six hours. Assign a human or configure Conversation AI before launch.
• Firing the workflow on every call status. Triggering on "completed" calls texts people you just spoke to. Filter strictly on missed (and tested voicemail/no-answer statuses).
• No tagging or opportunity creation. Without the tag and pipeline stage, you cannot prove ROI, and the client cancels an automation that was quietly making them thousands.

Frequently asked questions

Does missed call text back work with any GoHighLevel phone number?

It works with LeadConnector numbers and connected Twilio numbers, provided the number supports two-way SMS. In Australia, check SMS capability before purchasing and avoid alphanumeric sender IDs, which cannot receive replies. Calls must route through the GHL number for the Call Status trigger to fire, so configure forwarding there rather than on the client's carrier.

Is it legal to text someone back after a missed call in Australia?

Yes. Under the Spam Act 2003, a caller contacting your business creates inferred consent for a directly related response. You must still identify the sender in the message and provide a working opt-out for ongoing messaging. Enable GHL's location-level SMS compliance settings so STOP requests are honoured automatically.

How fast should the text go out after a missed call?

Between 30 and 60 seconds. Instant sends collide with voicemail and with owners who return the call immediately; anything beyond five minutes loses the caller to a competitor. A 45-second wait step is the sweet spot I use across every sub-account I manage.

What reply rate should I expect from a missed-call SMS?

Well-written, well-timed messages typically see 30–50% of recipients reply, based on the Australian sub-accounts I audit. Your close rate on those replies depends on response speed, which is why pairing the workflow with Conversation AI or a dedicated human responder matters more than the SMS copy itself.

Do I need A2P 10DLC registration for missed call text back?

Only if you are sending to US phone numbers. Unregistered US traffic is filtered by carriers and your texts will not deliver. Australian-to-Australian SMS does not use 10DLC, but it is governed by the Spam Act and ACMA rules instead, including sender identification and opt-out requirements.
