Most businesses measure the leads they got. Almost nobody measures the ones that arrived and were never answered, because that number does not appear in any dashboard by default and nobody enjoys going to look for it.
It is also, for most small and mid-sized businesses, the largest single leak in the funnel , and unlike almost everything else in marketing, it costs nothing to measure and nothing to fix except attention.
The arithmetic, using your numbers
- Count every inbound enquiry last month. Every channel: forms, email, phone, chat, Instagram DMs, the WhatsApp number on the van.
- Count how many got a real reply within an hour.
- Subtract. That is the gap.
- Multiply the gap by your average order value, then by your usual close rate.
That last figure is what silence cost you last month. Notice that nothing in this calculation is borrowed from an industry benchmark. We are not going to tell you that seventy-eight per cent of anything happens, because when we went looking for the sources behind the statistics in this category, several of the most-quoted ones turned out not to have any.
Why an hour, and not a day
Because the comparison is not you against your own service standard. It is you against whoever else they messaged in the same ten minutes.
The best evidence for this is old but solid: a Harvard Business Review study published in 2011, which audited 2,241 US companies and analysed 1.25 million leads. Firms that made contact within an hour were nearly seven times as likely to qualify the lead as those trying an hour later, and more than sixty times as likely as those who waited a day.
Two other numbers from that study are the ones that stay with you. The average response time was 42 hours. And 23% never responded at all.
Somebody has probably shopped your industry
Before you conclude your business is unusual, check whether anyone has measured yours. Pied Piper has been running genuine third-party mystery shops in the automotive industry for over a decade, submitting real enquiries and scoring what comes back over 24 hours. Conversica shopped 100 companies over 22 days in 2023 and found one in four never replied; that one is vendor research and should be read as such, but the methodology was published.
If nobody has shopped your industry, that is not a reason to assume the best. It is a reason to shop yourself.
Where the enquiries actually go
An enquiry arrives at 9pm on a Sunday, or while the one person who answers them is with a customer, or from a country eight hours ahead. It sits. By the time somebody opens it, the person who sent it has messaged two competitors and booked with whoever replied first.
The lead was not lost at the point of sale. It was lost at the point of silence.
Which produces the uncomfortable shape of this problem: the busier you are, the more you lose. A quiet week has no unanswered enquiries. A record week has plenty. The leak scales with success, which is exactly when nobody has time to look at it.
An auto-responder is not a reply
The usual first fix is an automatic acknowledgement, and it buys almost nothing. “Thanks, we will be in touch” answers no question, asks no question, and tells the reader they have joined a queue.
A first reply that is worth sending does three things: it answers something they actually asked, it asks one useful question back, and it sets an expectation the business can meet. That is not a template. It is a conversation, which is why it has historically required a person, and why it has historically not happened at 9pm on a Sunday.
Do it this week
Pick last month. Pull the enquiries. Count the replies inside an hour. You will have your number in under an hour of work, and it will be your number rather than an average of somebody else’s customers.
Almost every business that does this exercise is surprised, and almost none of them are surprised in the good direction.
Questions people ask about this
How do I calculate the cost of unanswered enquiries?
Count every inbound enquiry last month across every channel. Count how many received a reply within an hour. Subtract to get the gap. Multiply the gap by your average order value and by your usual close rate. That figure is what silence cost you last month, using your own numbers rather than anyone else’s benchmark.
Why measure response within an hour rather than a day?
Because the comparison is not you against your own service standard, it is you against whoever else the customer messaged in the same ten minutes. A Harvard Business Review study of 2,241 companies found that firms making contact within an hour were nearly seven times as likely to qualify the lead as those trying an hour later.
What percentage of businesses never reply at all?
The Harvard Business Review audit found 23% of the companies it studied never responded. A 2023 mystery shop of 100 companies by Conversica found one in four did not respond to an inbound lead at all. Conversica sells lead follow-up software, so treat that figure as vendor research, but the methodology was published and the finding is consistent with the older independent work.
Where do most unanswered enquiries come from?
From the hours nobody is working and the moments everybody is busy. An enquiry that arrives at 9pm on a Sunday, or while the one person who answers them is with a customer, or from a country eight hours ahead, is the one that sits. The problem therefore scales with how busy the business is, which is why it tends to get worse as a company grows.
Is a fast auto-reply good enough?
No. “Thanks, we will be in touch” answers nothing, asks nothing and signals a queue. A first reply that is worth sending answers something the customer asked, asks one useful question back, and sets an expectation the business can actually meet.
The short version
You already paid to make those enquiries arrive. The cheapest growth available to most businesses is not more traffic; it is answering the traffic they already have.
Ampa answers the ones nobody got to.
It replies in seconds at any hour, in the visitor’s own timezone, qualifies the enquiry properly, and hands your team a brief rather than a chat log.
