Reply within the hour during opening hours, and make that first reply come from a real person who can book the next step. The best-known study on this found that firms which tried to reach a new enquiry within an hour were nearly seven times as likely to have a meaningful conversation with a decision maker as firms that waited even an hour longer, and more than sixty times as likely as firms that waited a day or more.
What the research actually says
The figure most people quote comes from The Short Life of Online Sales Leads, published in Harvard Business Review in March 2011. The authors audited how 2,241 US companies answered web enquiries. Their findings, in their words:
- Firms that tried to contact a potential customer within an hour were “nearly seven times as likely to qualify the lead” as those that tried even an hour later, and “more than 60 times as likely” as those that waited 24 hours or longer.
- 37% responded within an hour, 24% took more than 24 hours, and 23% never responded at all.
- Among companies that did respond within 30 days, the average response time was 42 hours.
Two honest caveats. The study is from 2011 and looked at larger US firms, not five-person businesses. And “qualify” meant reaching a decision maker for a real conversation, not winning the sale. Still, there is little reason to think customers have grown more patient since, and the direction is hard to argue with: the enquiry cools fast, and plenty of businesses are slower than they think.
Why the first hour matters so much
An enquiry is a moment, not a record. The person who filled in your form had the problem in front of them right then: the leaking pipe, the contract to review, the tooth that hurts. Give it a few hours and they may have solved it, asked someone else, or gone back to their day.
They have also rarely asked only you. If three businesses get the same enquiry, the first one to reply properly sets the terms of the conversation: it asks the questions, offers the times and becomes the default. The others are now being compared against it.
Targets a small team can actually keep
A target you miss every day is worse than a modest one you hit, because the team stops believing it. These are sensible starting points, not industry benchmarks. Write yours down, keep them for a month, then tighten.
- Website form or email enquiry: a personal reply within one working hour.
- Missed call or voicemail: a call back the same morning or afternoon.
- WhatsApp or SMS, where the person messaged you first: within one working hour, in the same channel they used.
- Anything arriving out of hours: first thing the next working morning, before anything else.
An instant automatic “thanks, we got it” email is fine, but it does not count. The clock stops when a person replies with something useful.
Make it someone’s job
Slow replies are almost never laziness. They come from enquiries that belong to nobody. A form lands in a shared inbox, everyone assumes someone else has it, and by the afternoon it is a day old.
Give every enquiry one owner the moment it arrives, or put it in a shared queue where whoever is free claims it. A claimed enquiry with a next step and a time on it is one nobody has to remember.
In GuardenerAI, website form enquiries arrive as leads marked New. They do not get an owner automatically, and nobody is alerted when one arrives, so build the check into the day instead: look at new leads at fixed times (start of day, late morning, after lunch, end of day) and claim each one from the queue with Accept. That turns “within the hour” into something a small team can do without watching an inbox.
Write a first reply that books the next step
Speed only helps if the reply moves things forward. A good first reply:
- Uses the words the person used, so they know a human read it.
- Answers the one thing they asked, even briefly.
- Offers a single next step: a call at a time, or a link to pick one.
- Is signed by a real name with a direct number.
A booking link that shows only the times you are free saves a round of “does Tuesday work?” emails, which is often a day on its own.
Measure it once a month
Take the last twenty enquiries, note when each arrived and when a person first replied, and work out the share answered within your target. You do not need software for this; a list is enough. The point is to see where the slow ones cluster: out-of-hours forms, one channel nobody checks, or one person’s day off.

Frequently asked questions
Is five minutes really better than an hour? You will often see “reply in five minutes” quoted, but the source we could open and check compares within an hour against later. Aim for the hour reliably before chasing minutes.
Does an auto-reply count as a response? It tells the person their message arrived, which is polite. It does not count, because it cannot answer their question or book the next step.
What if we only check enquiries once a day? Then start by checking twice: first thing and mid-afternoon. That alone moves most enquiries from next-day to same-day. Our speed-to-lead playbook has a fill-in target table and a follow-up cadence for after the first reply, and the follow-through gap covers what happens after that.
