Missed call text back is one of the simplest automations a small business can set up, and one of the most useful. When someone calls and you cannot answer, the system automatically sends them a text message within moments. Instead of a missed call turning into a lost customer, it turns into a conversation.
This guide explains how missed call text back works, what to write in the message, the rules to follow, and how to set it up step by step.
What Is Missed Call Text Back?
Missed call text back is an automation that detects when an inbound call to your business number goes unanswered and immediately sends the caller an SMS. A typical message says sorry for missing the call, asks how you can help, and often includes a booking link.
HighLevel describes the feature simply: it “automatically sends a text message to callers you weren’t able to reach, so every inbound call gets acknowledged right away — even after hours” (HighLevel Support).
Why It Matters for Small Businesses
Think about what happens when a potential customer calls and nobody answers. Many will not leave a voicemail. They simply call the next business on the list. A fast text keeps you in the running because:
- It acknowledges the caller right away, even when your team is busy or closed.
- Texting is convenient. The caller can reply when it suits them, without waiting on hold.
- It creates a written record of what the customer needs, so you can follow up properly.
- It can book the appointment for you if you include a calendar link.
- It works 24/7, including evenings, weekends, and holidays.
For service businesses where the owner is often on a job site, such as contractors, cleaners, salons, and repair shops, this alone can rescue enquiries that would otherwise disappear.
How Missed Call Text Back Works
The basic flow looks like this:
- A customer calls your business number.
- The phone rings for a set time (the ring timeout).
- Nobody answers, so the call is marked as missed.
- The system sends your pre-written text to the caller’s number.
- The caller replies, and the conversation lands in your inbox or CRM.
- Optional: follow-up steps run, such as a reminder text, a task for your team, or a booking link.
Missed call text back software usually needs your calls to route through a phone number it controls, such as a number provided by your CRM or phone system. If you want to keep your existing number, ask your provider about porting or call forwarding options.
Missed Call Text Back Message Templates
Keep your message short, friendly, and clear about the next step. Here are a few templates you can adapt:
General service business:
“Hi, this is [Business Name]. Sorry we missed your call! How can we help? Reply here or book a time that suits you: [booking link]”
Home services:
“Hi from [Business Name]. We’re on a job right now and couldn’t pick up. What can we help you with? Reply with your address and the issue, and we’ll get back to you shortly.”
Appointment-based business:
“Thanks for calling [Business Name]! Sorry we missed you. You can book your next appointment here: [booking link] or reply to this text and we’ll help.”
After hours:
“Hi, thanks for calling [Business Name]. We’re closed right now but will reply first thing tomorrow. If it’s urgent, reply URGENT and we’ll do our best to help.”
Tips for better messages:
- Use your business name so the person knows who is texting.
- Ask one simple question.
- Do not promise a response time you cannot keep.
- Avoid long links or heavy sales language.
Compliance Basics: Read This Before You Turn It On
Business texting in the US has rules, and carriers are strict about them.
- Register for A2P 10DLC if required. Twilio’s documentation states that “anyone sending SMS/MMS messages over a 10DLC number from an application to the US must register for A2P 10DLC” (Twilio). Most CRMs that offer texting walk you through this registration.
- Only reply about the call. A missed call text back is a response to someone who contacted you. Do not add them to marketing campaigns without proper consent.
- Honor opt-outs. If someone replies STOP, they should not receive further texts.
- Check your industry’s rules. Healthcare, finance, and legal businesses may have extra privacy requirements.
This is general information, not legal advice. If you are unsure, check with your provider or a legal professional.
How to Set Up Missed Call Text Back in GoHighLevel
GoHighLevel (HighLevel) includes missed call text back as a built-in feature alongside its CRM, calendars, and texting tools. Based on HighLevel’s current help article, the setup works like this:
Step 1: Open Settings
In your sub-account, click Settings in the bottom-left corner.
Step 2: Go to Phone System and Voice
Click Phone System in the left menu, then Voice in the top navigation, and open Voicemail & Missed Call Text Back. Select Missed Call Text Back in the side panel.
Step 3: Enable the feature
Tick the box to Enable Missed Call Text Back, then click Customize to edit the message.
Step 4: Write your message
Type your message in the editor. You can insert custom values such as the contact’s name, but HighLevel notes these only work if the system already recognizes the contact.
Step 5: Send a test and save
Send a test message to your own phone to check how it looks, then click Save.
Step 6: Adjust the ring timeout
In the voicemail settings, set how long the phone rings before the call counts as missed. HighLevel’s article says 10 to 20 seconds is typically recommended.
One important detail from HighLevel’s documentation: the feature sends a text for every missed call, even if the same person calls several times in a short period. To avoid repeat texts, HighLevel recommends customizing the workflow recipe, for example by adding a wait step or filtering with tags (source).

Missed Call Text Back Automation: Going Further
Once the basic text is working, you can build a small automation around it:
- Booking link: include your calendar link so callers can book without waiting.
- Follow-up: if there is no reply after a set time, send one friendly reminder.
- Team alert: notify the right staff member by text or app notification.
- Tagging: tag the contact as a missed caller so you can track how many become customers.
- AI replies: some businesses add an AI assistant that answers common questions by text, then hands off to a person.
Common Mistakes to Avoid
- Sending multiple texts to someone who called several times
- Using a message that sounds like spam or has no business name
- Not monitoring replies, so the customer texts back and nobody answers
- Skipping A2P 10DLC registration, which can cause messages to be filtered
- Adding missed callers to promotional lists without consent

FAQs
Does missed call text back work with my existing phone number?
It depends on your setup. Many systems need calls to route through a number they manage. Some allow call forwarding from your current number or number porting. Check with your provider.
Is missed call text back legal?
Replying by text to someone who just called you is a common practice, but business texting in the US must follow carrier rules, including A2P 10DLC registration where required, and you must honor opt-out requests. Avoid using the text for unrelated marketing.
What should a missed call text back message say?
Include your business name, an apology for missing the call, a simple question, and optionally a booking link. Keep it under a few sentences.
Can I stop it from texting the same person twice?
Yes, in most systems. In HighLevel, the recommended approach is to customize the workflow with a wait step or tags so repeat callers are not texted every time.
What is the difference between missed call text back and an AI receptionist?
Missed call text back sends a text after a call is missed. An AI receptionist answers the call itself. Many businesses use both together.
