What is the best way to follow up on missed calls automatically?
The most effective approach, backed by lead response research, is immediate text follow-up within seconds of the missed call.
Not an hour later. Not at the end of the day. Within seconds.
Here's why timing matters so much: research shows that the odds of converting a lead drop by 10x if you wait longer than an hour to respond (Harvard Business Review). Within that first hour — and ideally within the first five minutes — a customer who didn't reach you is still thinking about you. They haven't fully committed to a competitor yet. There's still a window.
An AI-powered text within 30 seconds of a missed call hits that window every time.
What should an automatic missed call text say?
The most effective automatic response does three things:
A good example: "Hey! Sorry we missed your call — we're probably with a customer. I'm the AI assistant for [Business Name]. What can I help you with today? I can answer questions, check availability, or get you scheduled."
Short. Responsive. Opens the door to a real conversation.
The customer who gets that text within 30 seconds of hanging up doesn't call the next company. They reply. The conversation starts. The booking happens.

What percentage of missed call texts actually get a response?
SMS response rates are dramatically higher than any other follow-up channel. Industry data shows 45% of people respond to business text messages (Business.com) compared to just 6% for email and far lower for voicemail callbacks.
For missed call recovery specifically, the response rates are even higher — because the customer reached out first. They wanted something. They're not a cold lead. They're a warm one who just couldn't get through. The text gives them a frictionless way to pick up where they left off.
Can AI actually book appointments without a human involved?
For the vast majority of small business appointment types — yes.
The AI gathers the necessary information (service needed, location or address, preferred time), checks against a set of available windows you define, and confirms the booking. The customer gets a confirmation text. You get a new appointment.
No phone tag. No back-and-forth. No missed opportunity because you were finishing a job and couldn't respond in time.
Polu.ai handles this full flow across SMS and WhatsApp. When a call goes unanswered, the system texts back automatically. When the customer replies, the AI takes it from there. You review your calendar at the end of the day and find it fuller than it was in the morning.
