TL;DR Automated SMS for Missed Calls 

  • What it is: Missed call text back = an automatic SMS/text message to anyone you couldn’t pick up the phone for.
  • Why it matters: Keeps potential clients from calling the next business, saves team time, keeps messages on-brand, and logs to your CRM.
  • Setup: Use a tracking number, enable the call text back feature, customize timing, add a clear action (reply or booking link), and add routing rules.
  • Compliance & delivery: Follow consent rules (opt-out via STOP, A2P where needed), avoid PII, and note landlines can’t receive texts.
  • Track KPIs: missed-call rate; send/delivery; time to first response; reply; qualified conversations; bookings; revenue per missed call; cost per booking; opt-out; contactability; A/B lift.

What is a Missed Call Text Back?

A missed call text back happens when you receive a call, don’t answer, and an SMS/text message automatically goes to the caller. Example: “Hey [Name], I just missed your call—can I help you? You can reply to this text or use the link to book an appointment.” The goal: reply instantly to potential clients so they don’t call the next business.

Why is a fast text back is important?

In numbers, it’s important to be fast and be the first to respond before the lead moves on to the next business:

  1. Statistically, you are 100x more likely to win a deal when responding within 5 minutes of contact compared to waiting 30 minutes.
  2. 35 – 50% of customers choose the first business/vendor that responds to them

How does missed call text back work (step by step)?

  1. Use a tracking number that forwards to your business phone number.
  2. Enable the call text back feature so the system detects unanswered calls and triggers a text message.
  3. Customize messages and timing (after-hours, weekends, etc.).
  4. Add a clear action (tell me what you need, booking link, form).
  5. Set routing rules by number, hours, or queue.

Benefits of missed call text back (why does this work?)

  • Immediate response even if you didn’t pick up the phone, reducing churn to competitors.
  • Real-world behavior: need a beehive removed? Most people call down the list—your auto-SMS (“I’m on a job; book bee removal/inspection here”) keeps them with you.
  • Saves time: fewer manual follow-ups; your team can still call back with context.
  • Lean operations: brand-consistent templates, links, hours; everything streamlined.
  • Attribution: CRM tracking shows what’s working.

Best practices for missed call text back

  • Busy or queueing? Say you’ll call back ASAP and set expectations.
  • Online scheduling: include a booking link to eliminate phone tag.
  • CRM + tagging: attribute lead source and the missed-call workflow to prove revenue impact.
  • Pair with voicemail: different SMS if voicemail is left vs not; you can also text after a voicemail.

Use cases for missed call text back

  • Exterminator PPC / rodent problem: send “Free inspection—schedule here. Prefer a call? Reply and I’ll ring you back immediately.”
  • Real estate: auto-send open-house info and offer a personalized showing; speed-to-lead wins.

Compliancy and deliverability for missed call text back

  • Follow consent and legal rules (vary by U.S. vs GDPR countries).
  • Always provide opt-out (e.g., reply STOP) so the system removes them from SMS marketing.
  • Toll-free vs local codes both work; local can feel more personal, toll-free fits national brands.
  • Landline callers can’t receive SMS; those attempts bounce.
  • Avoid PII in plain SMS when required; use safe links.
  • Register for A2P when applicable before sending, or platforms like GoHighLevel won’t deliver.

KPIs for missed call text back

  • Missed-call rate = missed / total inbound calls (reduce over time).
  • Auto-text send rate = texts sent to missed callers / missed calls (aim near 100%; minus landlines/invalid).
  • SMS delivery rate = delivered / sent (watch long-code registration).
  • Time to first response (SMS) = seconds from call end to text (target instant, <60s).
  • Reply rate = replies / delivered (primary engagement).
  • Qualified conversation rate = qualified exchanges / replies (quality of replies).
  • Booking rate from missed-call texts = bookings from these texts / delivered (or / replies—be consistent).
  • Revenue per missed call = revenue from these leads / texts sent.
  • Cost per booked appointment = (SMS + software + labor) / bookings.
  • Opt-out rate = STOPs / delivered (monitor frequency/wording).
  • Contactability rate = SMS-capable missed calls / all missed calls (your ceiling).
  • A/B test lift = metric change vs control (test CTA, delay, first line, link placement).

Testing missed call text back

What to test first: the hook (opening line) and the CTA.

Hooks

  • Variant A: “I’m on a job right now—”
  • Variant B: “Sorry, we just missed your call—”

CTAs

  • Variant A: “Reply to this text and tell me what you need.” (encourage a response)
  • Variant B: “Book an appointment here:” + link (action via link)

How to run it

  • Start with a simple A/B (hook only). Then test the CTA. Or run a 2×2 (Hook × CTA) if volume allows.
  • Keep everything else the same (number, timing, signature).

Measure using the KPIs above

  • Reply rate and qualified conversation rate for the “Reply” CTA.
  • Booking rate for the link CTA.
  • Time to first response, delivery, opt-out, and revenue per missed call.

Rollout

  • Pick the winner, then iterate on wording and link placement. Keep changes small and keep testing.
