Missed call text back: what it is and what to send.

What missed call text back does

Missed call text back is a phone setting that texts a caller automatically when their inbound call is not answered^[1]. The caller rings, nobody picks up, and a short message arrives from your business number a few seconds later.

That message does three things. It tells the caller you know they called. It gives them a way to keep going by text, which suits someone standing in a flooded basement or sitting in a meeting. And it gives your office a written thread to pick up when someone is free, instead of a voicemail that may never be left.

Most service businesses miss calls for ordinary reasons: the owner is on a roof, the front desk is on another line, or the call comes in after five. None of that is a failing. It is the shape of a business where the people who answer the phone are also the people who do the work.

Why a missed call can be a lost job

A missed call can be a lost job because the caller has a problem now and the next business in the search results is one tap away. A homeowner with no heat does not wait for a callback window. They call down the list until someone responds.

Speed matters for written inquiries too, and there is published research on how quickly the odds of reaching a new lead fall. That study, its method and its limits are covered in how fast to respond to a new lead.

The text back does not win the job by itself. What it does is hold the caller long enough for a person to reply properly. Treat it as the first line of a conversation, not the whole of one.

What the text should say

The text should name your business, say you missed the call, ask one useful question, and say how to stop the messages. Keep it short enough to read on a lock screen.

• Who it is from. The caller may not have saved your number. Lead with the business name.
• What happened. "Sorry we missed your call" is enough. Do not pretend the line was busy.
• One question. "What can we help with?" or "Is this about an existing job or a new one?" A reply to a question gives your office something to act on.
• When a person will follow up. Only promise a time you can keep. If evenings are not covered, say a person will reply in the morning.
• How to stop. Industry guidance says standardized "STOP" wording should be used for opt-out instructions^[2].

An illustration, not a script from any real business: "Hi, this is [Business name]. Sorry we missed your call. What can we help with? A person will reply by 9 tomorrow morning. Reply STOP to opt out."

Leave sales offers out of it. The caller asked you something; the text back exists to answer that, not to pitch.

Consent and the STOP line

A missed call text back should be a direct reply to the caller and nothing more, and it must honor a request to stop. The wireless industry's guidance says that when a consumer starts a text message exchange and the business only responds with relevant information, no written permission is expected^[2]. A missed call is a phone call, not a text, so that guidance does not squarely cover it; keep the reply strictly about the call they made and nothing more.

Stopping has to work in plain language. Under the FCC's rule, a reply of "stop," "quit," "end," "revoke," "opt out," "cancel," or "unsubscribe" to a text is a reasonable way to revoke consent, and replies in other words count when a reasonable person would read them as a request to stop^[3]. The same rule says a revocation must be honored within a reasonable time not to exceed ten business days^[3].

Business texting from a local number in the United States also has a registration step: on that channel, brands are verified before they are allowed to send messages^[4]. That is a separate job, covered in A2P 10DLC registration for a small business.

Rules vary by state and by situation, and this guide is not legal advice. Your own counsel has the final word.

Setting it up in the CRM

In GoHighLevel, missed call text back is a setting in the phone system: you enable it, write the message, send yourself a test, and save^[1]. Its help page also covers two settings worth knowing before you switch it on.

• The ring timeout decides what counts as missed. The help page says the incoming call timeout sets how long the phone rings before the text back triggers, and that 10 to 20 seconds is typically recommended^[1]. Too short and you text people who would have been answered.
• Repeat callers get repeat texts. The feature sends a text for every missed call, even when the same caller tries several times in a short window, and the help page suggests a workflow with a wait step to avoid sending multiple messages^[1].
• Answered calls are left alone. Answered calls do not trigger a text back^[1].
• The text may come from a different number. If the number the customer called cannot send SMS, the system may pick another eligible number in your account^[1]. Tell your office so a reply from that number is not mistaken for spam.

Send the test to your own phone and read it as a stranger would. If it does not say who you are in the first few words, rewrite it.

What a text cannot do

A text back cannot answer an urgent call, so it should never be the only plan for emergencies. Someone smelling gas or watching water come through a ceiling needs a person or an emergency line, not a question about whether this is a new job.

1. Decide which calls are urgent for your trade and write them down.
2. Give those callers a number that reaches a person after hours, and say so in your voicemail greeting.
3. Let the text back handle everything else, and check the replies at set times each day.
4. Read a week of text back threads and count how many got a human reply the same day. That count is the number to watch.

If the gap is the answering itself, that is a different fix: a receptionist or an AI agent that picks up the line and says it is an AI. Our Conversation pillar covers that.
