Text back automation sends an automatic text message to a caller the moment you can't pick up, so the lead hears from you in seconds instead of going to the next business on their list. Done well, it uses your existing number, sounds like a person, hands the conversation to a human, and respects Canada's anti-spam law. Done badly, it annoys people and creates compliance headaches.
We're Launch & Found, a marketing agency in London, Ontario. We work with businesses across multiple industries, not only one trade, and we also serve surrounding Ontario service areas. Here is how we'd set this up if it were our own phone line.
TL;DR
- Text back automation fires an SMS after an unanswered call. It works best when it comes from the number the caller dialed and invites a reply.
- Keep the message short, name your business, apologize once, and ask one open question.
- Two-way texting matters: a reply that lands in an inbox nobody watches is worse than no text at all.
- In Canada, CASL applies to commercial texts. Identify yourself, offer a STOP reply and a web unsubscribe link, and keep records.
- Test the whole path end to end before you go live, then review it weekly.

What text back automation actually does
A missed call is a lead you paid for. You paid for it through ads, a website, a Google listing, or years of reputation. When nobody answers, most callers don't leave a voicemail. They call the next name in the search results.
Text back automation closes that gap. The system detects an inbound call that went unanswered (no answer, busy, or dropped) and sends a predefined SMS to the caller. The message acknowledges the miss and gives the person an easy way to continue: reply by text, tap a booking link, or wait for your callback.
Three terms get mixed up, so here is the plain version:
- Missed call text back: an automatic message triggered by an unanswered call.
- Automated text reply for leads: the same idea, but also covering new form fills, web chats, or inbound texts that arrive when you're closed.
- Two-way texting: the caller answers, and a real person on your team replies from a shared inbox.
The first one is a trigger. The third one is what turns a trigger into a booked job. You want both.
Who gets the most from it
Any business where the phone is the front door. Think of a roofer on a ladder, an HVAC technician under a furnace, a dental front desk with a patient at the counter, a salon stylist with foils in someone's hair. These people physically cannot answer, and the caller is often ready to buy now.
That is why we see this most often with contractors and local service businesses around London, Kitchener-Waterloo, Sarnia, Hamilton and across Southwestern Ontario. But a law firm, a clinic, or a retailer with a busy counter has the same problem on a different day.
How to set it up, step by step
The exact menus depend on your phone platform, but the logic is the same everywhere. Here is the order we'd work in.
1. Choose the trigger
Start with genuinely missed calls only. Typical statuses are no answer, busy, failed, and canceled. Decide which of those should send a text. Most businesses want all four.
2. Exclude numbers that shouldn't get a text
This is the step people skip, and it causes the most embarrassing mistakes. Build an exclusion list:
- Your own team's phones, so staff don't get texted when they call the office.
- Existing vendors, suppliers and family.
- Landlines. A text to a landline goes nowhere, so filter to mobile numbers where your platform allows it.
- Numbers that called back within the last minute or so.
3. Add a short delay
Wait about a minute before sending. That gives the caller time to leave a voicemail and avoids texting someone who just called back and reached you. Don't wait too long, though. The value of the text comes from speed. Think seconds to a minute, not an hour.
4. Write the message
See the next section. Keep it under about 160 characters so it goes out as a single SMS.
5. Add business-hours logic
Your message at 2 p.m. on a Tuesday should differ from your message at 9 p.m. on Saturday. During hours, promise a callback soon. After hours, say when you'll reply.
6. Route replies to a shared inbox
This is the part that decides whether the whole thing works. Replies should land where the team can see them, assign them, and answer from the same business number. A no-reply number is a dead end. If you can't answer texts, don't send texts that invite them.
7. Handle opt-outs and cap frequency
Someone who texts STOP must be removed immediately across every automation you run. Also cap how often one number can receive an automated text, so a caller who rings three times in ten minutes doesn't get three messages. One per caller per hour is a conservative default; a longer window is fine too.
8. Test it from a real phone
Call your own business line from a cell phone that isn't on your exclusion list. Let it ring out. Confirm the text arrives, the sender number is right, the reply shows up in the inbox, and STOP works. Do it again after hours.
9. Review weekly
For the first month, check the log every week. Read the actual replies. You'll spot odd responses, wrong-number texts, and messages that need rewording.
What the text should say
Good text back messages share five traits:
- They name the business.
- They apologize once, briefly.
- They sound like a person, not a corporation.
- They ask one open question or offer one clear action.
- They don't use "press 1 for..." style instructions. It's a text, not a phone tree.
Good answer (during hours):
Hi, this is Maple Street Plumbing. Sorry we missed your call! What can we help you with? We'll get back to you shortly.
Good answer (after hours):
Hi, this is Maple Street Plumbing. Sorry we missed you. What do you need help with? We'll reply first thing tomorrow morning.
Walk-away answer:
Thank you for contacting us. Your call is important to us. Please visit our website or press 1 to schedule.
The first two sound like a neighbor. The last one sounds like a hold queue, and people ignore it. (Maple Street Plumbing is a made-up example, not a client.)
Match the message to the situation
A missed call at 3 p.m. is different from one at midnight. Keep two versions at minimum. If you serve emergencies, be careful: an automated message should never diagnose a problem or promise that someone is on the way. If the person reports something urgent, your team should follow your escalation procedure, and a human should make the call.
Two-way texting: where the leads are actually won
The automatic text gets the first reply. A person closes the deal.
Two-way texting means the caller answers and your team continues the conversation from the same business number. The best setups give you a shared inbox with assignment, internal notes, and saved replies, so no one has to ask the customer to start over when a different person picks up.
The three-line reply
When a reply comes in, a simple structure keeps your answers short and moving:
- Confirm what they asked.
- Clarify with one question, or two choices.
- Close with one link or one action.
Example: "Got it, a leaking hot water tank. Is it dripping or actively flooding? Reply here and we'll book you in today."
What to automate and what to hand to a person
Automation is a good fit for repeatable, low-risk tasks: appointment confirmations, simple qualifying questions, hours and service-area FAQs, and reminders. Hand off to a human the moment a message involves urgency, emotion, a billing dispute, an exception to your policy, or anything legally sensitive.
It also helps to sort replies into buckets, so each one triggers the right path: confirmation, cancellation, price request, support issue, wrong number, opt-out, and urgent escalation. Treating every reply the same is the most common way these programs go wrong.
Canada's rules: CASL and your texts
Before you switch anything on, understand that text messages count as commercial electronic messages under Canada's Anti-Spam Legislation (CASL). Location of your servers doesn't matter. If you're texting Canadian numbers, the rules apply.
Here is the practical summary, based on university CASL guidance:
- Express consent can be oral or written, and it lasts until withdrawn. It must be opt-in. Pre-checked boxes don't count.
- Implied consent can arise from a qualifying business relationship within the past two years, or from an inquiry within the past six months.
- Identification: the message must identify who is sending it and include contact details, such as a mailing address plus a phone number, email, or web address (or a link to them).
- Unsubscribe: for texts, offer a reply keyword such as "text STOP to unsubscribe" and a link to a web page where the person can unsubscribe. Requests must be honored within 10 business days, and in practice you should honor them immediately.
A missed-call text is usually a direct reply to someone who contacted you, which is a very different situation from a cold blast. Still, keep the paper trail. Log the call that triggered the text, the time it was sent, the message content, and any opt-out. If someone asks why they were texted, you can show it was a response to their own call.
Consent is also channel-specific. A customer who agreed to receive emails hasn't agreed to receive texts. If you plan to use texting for promotions after the first conversation, collect separate consent and record when and how you got it. For a deeper look at the consent, sender-identification and unsubscribe side of Canadian texting, see this guide to Canadian anti-spam texting requirements. If your situation is complex, such as regulated industries or large contact lists, talk to a lawyer who handles CASL.

What to check before connecting it to your phone system
Before you plug text back into your phone line or your lead tracking, run through this list:
- Is it one-way or two-way? Some tools only send. If replies can't reach your team, you've built a dead end. Confirm two-way texting is included, or whether it costs extra.
- Does it send from your main number? Callers trust the number they dialed. A random new number looks like spam.
- Is the full path validated? A genuinely missed call, an eligibility check, the delay, a last check before sending, a neutral message, and an assigned owner.
- Does a reply or callback stop further follow-ups? If a caller already talked to you, no more automated messages should go out.
- Are your internal numbers whitelisted? Staff phones should never trigger a text.
- Is there a rate limit? Repeat callers shouldn't be spammed.
- Who owns each reply? Name a person or a rotation, with a backup.
How to measure whether it's working
A text back setup should pay for itself in jobs, so track it like a lead source. Watch these numbers monthly:
| Metric | What it tells you |
|---|---|
| Missed calls per week | How big the gap was to begin with |
| Texts delivered | Whether the system is actually sending |
| Reply rate | Whether your message sounds human |
| Time to first human reply | Whether your team follows through |
| Booked jobs from missed calls | The number that matters |
| Opt-outs | Whether you're texting too often or the wrong people |
You'll find benchmark figures online from software vendors, and they vary widely by industry and by how fast the message goes out. Treat them as a rough guide, not a promise. Your own numbers after 30 to 60 days will tell you far more. We won't quote a result for your business because we don't know it until we look at your call volume and your follow-up process.
Common mistakes we'd steer you away from
- Texting your own staff. Whitelist internal numbers on day one.
- Sending to landlines. The message disappears and the log looks better than reality.
- Sending a wall of text. One short message. One question.
- No human on the other end. A text that invites a reply needs someone to read it, fast.
- Ignoring STOP. Suppress the number everywhere, immediately.
- Promising things automation can't deliver. No arrival times, no quotes, no diagnoses.
- Treating it as the whole strategy. Text back catches leads you've already earned. It doesn't create them.
That last point is where marketing comes in.
Our take: fast replies are a marketing decision
We see the same pattern with local businesses. They spend money to make the phone ring, through a website, ads, local search, and then the call hits voicemail. The marketing worked. The follow-up didn't.
That's why we don't treat lead response as an IT chore. It's part of the same system as your website and ads. A site that never rings the phone is a problem, but so is a phone that rings and goes nowhere.
Our approach is to look at the whole path: where the lead comes from, what they see, how quickly they hear back, and who follows up. Then we fix the weakest link first. Sometimes that's the ad. Sometimes it's the site. Sometimes it's the first thirty seconds after a missed call.
We work with businesses across multiple industries, not only one trade, with London, Ontario as our home base and clients across surrounding Ontario service areas. Every scope is tailored to the business, which is why pricing is by custom quote after we assess fit.

FAQ
What is a missed call text back?
It's an automatic SMS sent to a caller after their call goes unanswered. It acknowledges the miss and invites a reply, a booking, or a callback. It typically comes from the same number the caller dialed.
Do I need consent to send an automated text in Canada?
CASL covers commercial text messages, and it requires consent plus sender identification and an unsubscribe method. Consent can be express, or implied in some cases such as a recent inquiry. Because rules have detail and exceptions, check with a lawyer if you're unsure about your situation.
How long should I wait before the text goes out?
About a minute is a sensible default. That gives the caller time to leave a voicemail and avoids texting someone who called right back. Longer than a few minutes and you lose the speed advantage.
Can the caller reply to an automated text?
They can if you set it up for two-way texting. Replies should land in a shared inbox where someone on your team can answer from the business number. Confirm this before launch, because some tools only send.
Should I use text back for emergencies?
Use it to acknowledge the call, not to handle the emergency. Automation shouldn't diagnose anything or promise arrival times. If someone reports an urgent situation, your team should follow your escalation procedure and call them.
