Missed-call text back for contractors: how to set it up
When a homeowner calls a contractor and nobody picks up, they don’t leave a voicemail. They call the next company. Missed-call text back sends them a text within seconds, so the conversation keeps going while your team finishes the job in front of them.
What missed-call text back is
It’s an automation on your business phone number. When a call goes unanswered (no pickup after a set number of rings, or the call reaches voicemail), the system sends an SMS to the caller’s number. Replies come back as texts to your team, in a shared inbox or forwarded to a phone.
It only reaches callers on mobile phones. A text to a landline won’t arrive, so keep voicemail set up as well.
What you need to set it up
- A phone number that supports it. This feature is built into a range of phone providers and lead-management platforms. If your main line can’t, a common approach is to forward unanswered calls to a number that can.
- SMS registration. In the US, businesses texting from ordinary local numbers must register a brand and a messaging campaign (known as A2P 10DLC) through their provider. Unregistered messages are filtered or blocked by carriers, so do this first; approval can take days.
- A trigger. Decide what counts as missed: unanswered after a few rings, sent to voicemail, or both. Avoid texting people whose calls you answered.
- Someone who owns the replies. A text back that nobody answers is worse than none. Route replies to the office during the day and to whoever is on call at night.
What the first message should say
Short, from a named company, and about their call, not a promotion. Include how to opt out.
Hi, this is {Company}. Sorry we missed your call. We're on a job right now. What can we help with? We'll call you back shortly. Reply STOP to opt out.
Hi, this is {Company}. We're closed for the night but got your call. If it's an emergency, reply URGENT and our on-call tech will ring you. Otherwise, tell us what you need and we'll call first thing tomorrow. Reply STOP to opt out.
Keep these replies to the conversation the caller started. Adding people to promotional texts is a different matter with stricter consent rules; check with your SMS provider or a lawyer before you do. This guide isn’t legal advice.
Mistakes to avoid
- Sending from a number that doesn’t match the one they called, without saying who you are.
- Generic copy like “Thanks for contacting us!” that doesn’t invite a reply.
- No after-hours version, so a 9pm emergency gets a “we’ll call you back” and nothing until morning.
- Never testing it. Call your own number from a mobile, let it ring out, and check the text arrives.
How to tell if it’s booking jobs
Track four numbers each month, ideally with a tag on every lead that came through text back:
- Missed calls (from your phone system or call tracking)
- Text backs sent
- Replies received
- Jobs booked from those conversations, and their invoice value
The last number is the one that matters. If replies are high but bookings are low, the follow-up after the first text is the problem, not the text itself.
