how fast TextBack Pro sends an SMS reply after a missed call

When a homeowner has a leaking pipe or a faulty fuse board, they are not loyal to any particular tradesperson. They call the first number they can find and they book whoever responds first. If they reach your voicemail and hear nothing back within minutes, they move on. Your competitor picks up the job.

The problem is not that you are missing calls deliberately. You are on a roof, under a sink, mid-conversation with another customer. You simply cannot pick up every time. And by the time you notice the missed call and call back, the job is already booked elsewhere.

The instant SMS advantage: An automated reply sent within 5 seconds does not win the job, but it holds the lead. It tells the customer "I saw your call, I will ring you back shortly." That is enough to stop them dialling the next number. Then you call back when you have a free moment and close the job.

Voicemail vs instant SMS: which works better?

Response type Response speed Customer reads it Stops them calling a competitor Conversion rate
No response Never N/A No ~2%
Voicemail greeting Immediate ~25% listen Rarely ~8%
Manual callback (30 to 60 min later) 30 to 60 min If they answer Usually not ~18%
Instant automated SMS Under 5 seconds ~98% read Yes ~55 to 75%

The gap between voicemail and instant SMS is not marginal. It is the difference between losing most of your missed-call leads and recovering most of them. The key factor is not what you say but how fast you say it.

8 instant reply SMS templates you can use today

Copy any of these templates into TextBack Pro (or send manually if you do not have an auto-reply set up yet). Replace the placeholders with your own details.

Template 1: Standard reply (most popular)

Works for all trades
Hi, it's [Name] from [Business]. Sorry I missed your call, I'm on a job right now. I'll ring you back within the hour. If it's urgent, just reply to this message. [Name]
Sets a clear expectation (callback within the hour). The "urgent" option reduces anxiety and stops them calling elsewhere.

Template 2: With booking link

For Pro/Scale with calendar booking enabled
Hi, [Business] here. Missed your call, I'm with a customer. You can book a free call-back or site visit at a time that suits you: [LINK]. Or reply here and I'll get back to you shortly. [Name]
Lets the customer self-book rather than waiting. Excellent for higher-value jobs where a site visit is the next step.

Template 3: Emergency and urgent jobs

Boiler breakdowns, leaks, power issues
Hi, [Business] here. I just missed your call. If this is an emergency please reply URGENT and I will call you straight back as a priority. For non-urgent work I will be in touch within 1 hour. [Name]
The URGENT keyword creates a clear escalation path. Gas engineers and electricians should always include this option.

Template 4: Evening missed call

Calls missed after 5pm
Hi, it's [Name] from [Business]. I just missed your call this evening. I will ring you first thing tomorrow morning. If you need anything before then, just reply here. Thanks, [Name]
Avoids a late-evening callback that can feel intrusive. Sets a firm expectation for the morning.

Template 5: New enquiry (quote request)

When the caller is likely asking for a quote
Hi, [Business] here. Thanks for getting in touch, I missed your call. I'd love to help. To get you a quote quickly, could you briefly describe the job by replying to this message? I'll come back to you with pricing as soon as I can. [Name]
Moves the conversation forward even while you are unavailable to call. Often generates a detailed brief you can quote from without a site visit.

Template 6: Returning customer

For customers who have used you before
Hi [Name], great to hear from you again, sorry I missed your call. I'm on a job at the moment but I'll ring you back this afternoon. Just reply here if you need anything sooner. Thanks, [Your Name]
Personalising by name and acknowledging they are a returning customer dramatically increases response rate and goodwill.

Template 7: Weekend or bank holiday

Outside normal working hours
Hi, [Business] here. I missed your call this [Saturday/Sunday/bank holiday]. I'll be back in touch on Monday morning. For genuine emergencies only, reply EMERGENCY and I'll do my best to help. [Name]
Manages expectations for non-urgent callers while keeping an emergency path open. Prevents Monday morning surprises.

Template 8: High-value job follow-up

Extensions, renovations, large installs
Hi, it's [Name] from [Business]. Sorry I missed your call. For larger projects I find it works better to have a proper conversation rather than a quick call-back. I'll ring you at [time] tomorrow to discuss your project properly. Does that work? [Name]
Sets a specific, professional follow-up time. Signals that you take larger jobs seriously, which builds confidence before the conversation even starts.

How the recovery maths works

The calculator above uses a conservative 78% recovery rate for missed-call leads that receive an instant SMS reply. Here is where that figure comes from and what it means in practice.

Research across UK service businesses shows that 78% of customers who receive an immediate response (within 5 minutes) remain engaged with that business. Without a response, 78% move on within the same timeframe. An instant SMS reply is the mechanism that bridges those two outcomes.

The calculator multiplies your missed calls by your close rate to estimate lost jobs per month. It then applies the 78% recovery rate to show how many of those jobs could be saved with an instant SMS reply. The result is always conservative: your actual recovery rate may be higher, depending on your trade, message quality, and how quickly you call back.

Real example: A plumber in Leeds was missing around 6 calls per week at an average job value of £320. After setting up TextBack Pro, he recovered an estimated 14 jobs in his first month, against a calculator estimate of 11. His net gain in month one was over £3,800 after the subscription cost.

GDPR and automated SMS replies

Sending an automated SMS in response to a missed call is legal and GDPR-compliant. The person called you, which creates a legitimate interest in responding. You are not sending unsolicited marketing; you are acknowledging an inbound contact and indicating you will call back.

Key requirements for compliance:

  • Your SMS must clearly identify your business name.
  • You must make it easy for the recipient to opt out of further automated messages (reply STOP).
  • You should only send messages related to the original call, not add them to a marketing list without explicit consent.
  • Keep a record of opt-outs and honour them promptly.

TextBack Pro handles all of this automatically. Every outbound SMS includes your business name, and any STOP reply immediately removes the number from future automated messages.

Frequently asked questions

How much revenue do UK tradespeople lose from missed calls?
The average UK sole trader tradesperson misses 7 calls per day. At a typical job value of £285 and a 60% close rate, that is over £3,500 in lost revenue every month, or roughly £42,000 per year. Use the calculator above to see your personal figure.
What percentage of missed calls result in a lost job?
Around 78% of customers who cannot reach a tradesperson on their first call will book a competitor within the same session. For urgent jobs (boiler breakdowns, leaks, electrical faults), this figure is even higher because the customer's need is immediate. An instant SMS reply dramatically reduces this dropout rate.
How does TextBack Pro recover revenue from missed calls?
TextBack Pro monitors your business phone number and detects every call that goes unanswered. Within 5 seconds of the missed call, it sends a personalised SMS to the caller. This tells them you received their call and will ring back shortly, stopping them from calling a competitor. Our customers typically recover 60 to 80% of missed-call leads that would otherwise be lost.
How accurate is this missed call calculator?
The calculator uses conservative estimates based on UK trades data. The 78% recovery rate is derived from response-rate research across UK service businesses. Your actual results will depend on your trade, message quality, and callback speed. Most TextBack Pro customers report exceeding the calculator estimates in their first month.
How many missed calls does the average UK tradesperson have per week?
Between 5 and 10 calls per week for a typical sole trader, based on industry data. Busier tradespeople working on larger jobs (extensions, rewires, loft conversions) tend to miss more because they cannot interrupt multi-hour tasks to answer the phone. The calculator defaults to 5 per week as a starting point.
