Missed call text back. How it works and how to set it up.
A missed call text back sends the caller a text within seconds of a call you couldn't answer, like "Sorry we missed you, what can we help with?" Most callers who don't reach you call the next business on the list. A quick text keeps the conversation going until you can call back. It's one of the cheapest and fastest automations a small business can set up.
How does a missed call text back work?
- A customer calls your business number and you can't pick up.
- Your phone service sees the missed call and sends a text you've written ahead of time.
- The customer replies by text with what they need.
- You get a notification, and you reply or call back when you're free.
What should the text say?
Keep it short, friendly and about their call. Say who you are, that you'll get back to them, and ask one question that helps you reply.
Example: "Hi, this is Sam from Northside Plumbing. Sorry we missed your call, we're on a job. What can we help with? We'll text or call you back within the hour."
Only promise a reply time you can keep, and don't add offers or promotions to this text.
What do you need to set it up?
- A phone service or app that can send automatic texts. Many business phone apps have this built in. Your current one may already support it.
- A business number that can send texts, not just receive calls.
- Your message, written in your own words.
- Somewhere replies go that you'll actually check, like your phone or a shared inbox.
What are the texting rules in Canada and the US?
- Canada: commercial texts are covered by Canada's anti-spam law (CASL), which requires consent, your identification and a way to unsubscribe. Keep the text-back about the caller's own request, and ask before sending them promotions.
- US: wireless carriers require businesses texting from a regular 10-digit number to register (A2P 10DLC). Unregistered texts can be blocked. Most texting providers walk you through it.

Is a missed call text back worth it?
Work it out with your own numbers. Count the calls you miss in a normal week, guess how many of those would have become customers, and multiply by what an average job is worth to you. If that's more than the monthly cost of the tool, it's worth testing for a month.
Once it works, many businesses add more: an AI reply that answers common questions by text, or a full AI receptionist.

Common questions
What is missed call text back software?
It's a feature in a business phone app or texting tool that automatically texts anyone whose call you miss. Some tools add AI so it can answer simple questions in the text conversation.
Can I set up an automatic text for missed calls on my own phone?
Some phones and carrier apps have basic auto-replies, but they're often limited to while you're driving or busy. For a business number, a business phone app with a proper missed call text back is more reliable.
Is missed call text back the same as an AI receptionist?
No. A text back sends one message and waits for you. An AI receptionist answers the call or carries on the conversation itself. Many owners start with the text back.
Do I need consent to text someone who called me?
A text about the caller's own request is different from a marketing text, but rules still apply. Keep it about their call, and get consent before sending offers. In the US, also make sure your number is registered for business texting.
How fast should the text go out?
Within a minute of the missed call. The point is to reach the caller before they call someone else.
