Missed Call Text Back

Missed Call Text Back automatically sends an SMS when an inbound call goes unanswered. Within seconds of the missed call, the contact receives a customizable text message that opens a live conversation. This is the single most sellable automation in GHL. Every business misses calls, and every missed call is a potential lost customer. This feature turns that gap into a conversation.

Why This Matters

Businesses lose leads every time a call goes unanswered. After-hours calls, lunch breaks, busy phone lines, staff in meetings. The caller moves on to the next business in their search results. Missed Call Text Back catches them before they leave. A fast, friendly text saying “Sorry we missed your call, how can we help?” keeps the conversation alive and the lead warm.

For agencies, this is the easiest automation to sell. Every business owner knows they miss calls. Show them the feature in a demo, and the value is immediately obvious. No explanation needed, no education required. They see it and they want it.

How It Works

The automation runs through the Workflow Builder. The setup is straightforward:

1. Trigger: Call Status is “missed” or “no answer”
2. Wait step: Short delay (30-60 seconds) to avoid texting someone who immediately calls back
3. SMS action: Send a customizable text message

The message should be short, human, and conversational. Something like: “Hey, sorry we missed your call. How can we help?” Avoid robotic language, marketing speak, or long paragraphs. The goal is to sound like a person, not a system.

Logic Considerations

Don’t double-text. If someone calls twice and gets no answer both times, you don’t want them getting two identical texts. Add an If/Else branch that checks whether an SMS was already sent to this contact in the last hour.

Business hours variations. Consider different messages for business hours vs. after hours. During the day: “Sorry we missed you, we’re helping another customer. What can we do for you?” After hours: “We’re closed for the day but saw you called. We’ll follow up first thing tomorrow. What’s this about?”

Known vs. unknown callers. If the caller is already a contact in your CRM, the workflow can reference their name and past interactions. If they’re new, the text serves as both a response and a lead capture mechanism.

Setting It Up

Open the Workflow Builder, create a new workflow, and select the call event trigger. Filter for missed or unanswered calls. Add a 30-60 second wait step. Add an SMS action with your message. Test by calling the tracking number and letting it ring.

Make sure the sub-account has an active phone number with SMS capabilities. LC Phone numbers work out of the box. Twilio numbers require SMS-enabled configuration.

Deploying to Clients

Build the workflow once in a snapshot. When onboarding a new client, the missed call text back automation deploys automatically with the snapshot. Customize the message text per client (business name, tone, hours) and activate. Most clients see value from this automation within the first week.

Pro Tips

• Keep the message under 160 characters to avoid splitting into multiple SMS segments.
• Test the full flow yourself before activating for clients. Call the number, let it ring, verify the text arrives within 60-90 seconds.
• Add a second follow-up message 24 hours later if the contact hasn’t responded to the first text.
• Track conversion rates by tagging contacts who enter through missed call text back. This data proves ROI to clients.

Common Questions

Does this work with all phone number types?

It works with LC Phone and Twilio numbers that have SMS capabilities enabled. Numbers without SMS capability will trigger the workflow but fail on the send step.

What if the caller is already in a conversation?

Add a condition to check for active conversations. If the contact already has an open conversation thread from the last 24 hours, skip the automated text to avoid interrupting a live exchange.

Can I use this with Voice AI?

Yes. If Voice AI answers the call, missed call text back won’t trigger because the call wasn’t technically missed. They work as complementary features: Voice AI handles answered calls, missed call text back catches the ones that slip through.

How fast does the text send?

With a 30-second wait step, the contact receives the SMS roughly 30-45 seconds after the missed call. Fast enough to catch them while they’re still thinking about your business.
