Missed-Call Text-Back
Also written: missed call automation
Quick answer
What is missed-call text-back?
Missed-call text-back is an automation that sends an SMS immediately when an inbound business call goes unanswered. It typically acknowledges the missed call and offers to book or asks what the caller needs, converting a lost call into a text conversation.
It is usually the highest-return single automation available to any business that takes phone enquiries, and among the cheapest to build.
The reason it works is behavioural: most callers do not leave voicemail. Someone with an urgent problem calls the next number on the list rather than waiting for a call back. A text arriving within seconds keeps the conversation alive when the call itself was lost.
It matters most in trades and home services, where the people qualified to answer the phone are physically unable to, under a sink, on a roof, in a treatment room, for most of the working day.

- Workflow AutomationWorkflow automation is software that runs a defined sequence of actions automatically when a trigger event occurs. A form submission, inbound call or pipeline change starts the workflow, which then sends messages, assigns tasks, updates records, books appointments or calls external systems according to conditional logic.
- Speed to LeadSpeed to lead is the elapsed time between a prospective customer submitting an enquiry and the business making first contact. It is tracked because published research shows qualification rates fall sharply as response time increases, particularly beyond the first hour.
