Key takeaways
- Missed call text back sends an automatic text when a call goes unanswered, so the caller can continue by message.
- The first text should name the business, acknowledge the call and ask one simple question.
- Replies must reach a person quickly; the automation only buys a few minutes.
- Business texting in the US generally needs carrier registration, and marketing follow-ups need consent.
01
What is missed call text back?
Missed call text back is an automation that detects an unanswered call to your business number and sends the caller a text message within seconds, so they can explain what they need by text instead of calling a competitor. It suits businesses where calls arrive while staff are on a job, with a customer or out of hours — trades, clinics, salons and small offices.
It works because many callers are happy to text once someone acknowledges them. It fails when the text arrives and then nobody replies.
02
What should the first message say?
Keep it short, human and specific: the business name, an apology for missing the call, and one question that moves things forward. For example: “Hi, this is Northside Plumbing — sorry we missed your call. What can we help with? A person will reply shortly.” Avoid links and sales offers in the first message.
Do not pretend a person is typing if it is automated. Honest wording avoids confusion when the real reply comes.
| Element | Good | Avoid |
|---|---|---|
| Identity | Business name first | Unbranded number only |
| Tone | Brief apology and question | Hard sell or discount code |
| Promise | “A person will reply shortly” | Promising a time you cannot meet |
| Opt-out | Reply STOP handled automatically | No way to stop messages |
03
How do you route the replies?
Send every reply to a shared inbox or the CRM with a notification to whoever is on duty, and set a target response time the team can meet. If nobody replies within that time, escalate to a second person. Log the conversation on the contact record with the call as the source.
For after-hours calls, say when the business will be back and offer a booking link or emergency number if you have one.
- Replies land in one shared inbox or CRM
- On-duty notification and escalation
- Conversation logged with call as source
- After-hours wording and booking option
04
Which rules apply to automated texts?
A reply to someone who just called you is generally treated differently from unsolicited marketing, but rules still apply. In the United States, business texting over standard ten-digit numbers requires A2P 10DLC registration through your provider, and ongoing marketing texts need prior express written consent under TCPA rules. Honour STOP requests immediately.
Keep the missed-call text transactional. If you want to add the caller to promotions, ask for consent separately and record it.
