Design principles
- Identify the business — callers text with many businesses a day.
- Acknowledge the missed call, then give one simple next step or question.
- Set a realistic expectation: a callback window someone is assigned to keep.
- Keep emergency lines for businesses with a real staffed on-call workflow — [Emergency Line] is a promise, not a decoration.
- Offer a staffed reply path — every template below names its reply owner.
- Respect opt-outs and consent; see the compliance section below.
The template library
Twelve templates, each with its job description. Replace the [brackets] with your details. Copy, adapt, and — most importantly — assign the reply owner before you switch the automation on. Templates that promise a window (“within the hour”, “first thing tomorrow”) are safe only when someone is assigned and able to keep it — adapt or drop the promise otherwise. Templates that mention an emergency line are for businesses that actually staff one.
General service-business missed call
GeneralHi, this is [Business Name] — sorry we missed your call. We're with another customer right now. Text us back here or we'll call you by [Callback Window].
- When:
- Any unanswered call during the day, no context about the caller — use only when someone is assigned to keep the promised window.
- Tries to learn:
- Whether the caller is a prospect and what they need.
- Reply owner:
- The person on callback duty this shift.
- Next:
- Callback within the promised window; log the outcome.
- Never promise:
- A specific callback time unless someone is assigned to keep it.
During-business-hours missed call
GeneralHi, [Business Name] here — we saw your call come in while all our lines were busy. We'll call you back within the hour. Urgent? Reply URGENT and we'll bump you up.
- When:
- You are staffed and someone is assigned to callbacks — every line was busy.
- Tries to learn:
- Urgency and the nature of the job.
- Reply owner:
- Front desk or owner on duty.
- Next:
- Same-hour callback.
- Never promise:
- A 'within the hour' promise unless someone is assigned and can keep it.
After-hours — next-business-day response
After hoursHi, you've reached [Business Name] after hours. We're closed now but we'll call you first thing tomorrow morning (we open at [Opening Time]). If it can't wait, text URGENT and we'll do our best to respond tonight.

- Reply owner:
- First person in the next morning.
- Next:
- Callback in the first hour of the next business day.
- Never promise:

Emergency-capable business

Reply ownership — automation does not end at send
The text is the first half of the automation. The second half is what happens when the caller replies. Every template above names a reply owner and a response window because an unanswered reply is worse than no text at all: it converts a promising lead into proof that you are busy and disorganized. Before enabling text-back, answer three questions: who sees replies, how fast, and what happens after hours.
Compliance context (SMS)
In the United States, automated texts are regulated — principally under the TCPA and FCC rules — and business texting over standard 10-digit numbers requires 10DLC registration through The Campaign Registry, usually handled by your messaging provider. Requirements depend on message type, consent, jurisdiction, carrier and provider. Businesses are responsible for confirming the consent, registration and opt-out requirements that apply to their messaging. Nothing on this page is legal advice.
First message and opt-out
Where your provider or campaign requires it, an opt-out instruction belongs in the message — commonly a suffix such as “Reply STOP to opt out.” Your provider or carrier may also add sender identification and opt-out language automatically. Do not assume one wording satisfies every carrier, campaign type or jurisdiction; confirm with your provider and the current rules for your message type.
What not to send
| Bad pattern | Why it fails | What to do instead |
|---|---|---|
| Vague “we'll get back to you” | Sets no expectation | Name a window and an owner |
| False callback promises | Burns trust in one message | Only promise what is staffed |
| Too many questions | The caller wanted a callback, not a form | One question, or a booking link |
| Marketing disguised as service | Insults the caller's urgency | Serve first; promote later |
| Asking for sensitive details | Privacy and trust risk | Keep to logistics and a callback |
| Unmonitored two-way number | Replies die silently | Staff the reply path or stay one-way |
| Confirming bookings that are not booked | Sends callers to empty calendars | Book first, confirm second |
FAQ
| Question | Short answer |
|---|---|
| Should every template include an opt-out? | Where required for your message type and campaign — confirm with your provider. |
| Can I use a customer's first name? | Only where you reliably know it; wrong names are worse than none. |
| How fast should the text go out? | Seconds — the point is catching the caller while they still care. |
| What if the caller replies STOP? | Honor it — and make sure your sequence stops automatically. |
