How fast should you respond to a lead?

Acknowledge every inbound lead within seconds, and have a person reply within five minutes during working hours. Outside working hours, send an automatic acknowledgement at once and a personal reply in the first 30 minutes of the next working day. The research supports the direction (earlier contact leads to more conversations) more firmly than it supports any exact number of minutes.

Response time targets by situation

These are working targets we suggest for a sales team of 3 to 50 people. No study sets them. Adjust them once you have your own numbers.

“Working hours” means the hours you publish. If you say 08:00 to 18:00, an enquiry at 17:55 gets the five-minute treatment.

What the research supports

Two studies sit behind most advice on this topic. Both come from the United States, and both measured web forms followed up by phone or email.

• One hour. A March 2011 Harvard Business Review article by James Oldroyd, Kristina McElheran and David Elkington analysed 1.25 million sales leads at 42 US companies. Firms that tried to make contact within an hour were nearly seven times as likely to qualify the lead as firms that tried an hour later. The same article reports an audit of 2,241 US companies: 37% replied to a web lead within an hour and 23% never replied.
• Five minutes. A 2007 study of phone calls to web leads, presented by James Oldroyd (then at MIT) using a software company’s call records, covered more than 15,000 leads at six companies. It reported that the odds of reaching a lead were 100 times lower when the first call came at 30 minutes instead of five. The odds of qualifying the lead were 21 times lower.

The HBR page is partly behind a paywall, so we checked its figures against a reprint of the full text.

Read both with care. Neither measured closed sales. “Qualify” in the HBR article means a real conversation with a decision-maker. The samples are web forms from 2011 and earlier, and we have not found a published study of reply times on WhatsApp as of October 2026. So five minutes is a working target. Nobody has proved it as a threshold for chat.

Our guide to lead response time statistics and what the studies really say goes through each study, its sample and the popular figures that have no source.

Why minutes matter for an inbound lead

A person who has just sent an enquiry is still holding the phone. The chat is open, the question is fresh and they have a moment to answer yours. Twenty minutes later they are in a meeting, on a bus or reading another supplier’s reply.

In our experience, many buyers ask two or three companies at once. The first useful answer becomes the one the others are compared with. You will see exact percentages quoted for how many buyers choose the first company to reply. Our statistics guide could not trace those to a study, so we leave them out.

WhatsApp adds a practical reason. On the WhatsApp Business Platform, Meta’s documentation says a 24-hour customer service window opens when a person messages you. Once it closes, you can only send pre-approved template messages (as of October 2026; check the linked page for the current rule). A reply within minutes keeps the whole first conversation inside that window. Our guide to the WhatsApp 24-hour rule for sales teams explains the details.

What counts as a response

An automatic acknowledgement tells the lead the message arrived. It does not answer the question. Count the two separately, and set the five-minute target on the first reply that deals with what the person asked.

A good first reply does three things:

1. It names the person and your business.
2. It answers the question they asked, or says exactly when the answer will arrive.
3. It asks one question that moves the conversation forward.

An automatic acknowledgement:

Hi, thank you for contacting Kite Travel. We have your message and a member of the team will reply shortly. Our hours are 08:00 to 18:00, Monday to Saturday. Reply STOP at any time and we will not message you again.

The first reply from a person, four minutes later:

Hi Tolu, Amaka from Kite Travel here. Yes, we can arrange the Nairobi trip for a group of 12 in March. Do you have dates already, or should I suggest two options?

A fast reply that says only “we will get back to you” buys a little patience. The clock on the real answer keeps running.

The First-Hour Follow-Up Kit has scripts for the first hour after a lead comes in, plus a 7-day rhythm for what follows. It is one of the free Socianet sales tools.

Leads that arrive outside working hours

A team of five cannot staff a phone at 23:00, and no reasonable lead expects it. What a lead does expect is to know the message arrived and when a person will answer.

Say a lead messages Nile Motors at 21:40 on a Tuesday. A workable plan looks like this:

1. An automatic reply goes out at once. It gives the opening hours and says a person will reply after 08:00.
2. The enquiry lands in a list that Sam checks at 08:00, before anything else.
3. Sam replies by 08:30 with an answer and one question.

Hi, thank you for messaging Nile Motors. We are closed now and open again at 08:00. Sam or a colleague will reply to you then. Reply STOP at any time and we will not message you again.

If evening and weekend enquiries make up a large share of your leads, add a rota (one person checks at 20:00) or an AI agent that answers common questions and books a call. Measure the share first. For many teams it is smaller than it feels.

How to get under five minutes

1. Put every enquiry in one place. WhatsApp, web forms, email and social messages should land where the whole team can see them. If one phone in one pocket holds the number, reply time depends on that person’s day. See how several people can share one WhatsApp number.
2. Name an owner for every hour. A simple rota works: Amaka from 08:00 to 13:00, Tolu from 13:00 to 18:00. Whoever is on owns the first reply, even if a colleague takes the deal later.
3. Turn on alerts. Sound and screen notifications on the owner’s phone and laptop, for every channel.
4. Save replies to your five most common questions. Price, location, availability, delivery time and how to pay. Edit each one before you send it so it fits the person.
5. Switch on an automatic acknowledgement. The WhatsApp Business app includes greeting messages, away messages and quick replies, according to WhatsApp’s own feature page (as of October 2026).
6. Measure it every week. Record the median time to the first reply from a person, the share answered within five minutes and the share never answered.

If you get fewer than ten enquiries a week, one attentive person with the WhatsApp Business app and a spreadsheet can hit these targets. Shared tools start to matter when enquiries arrive on several channels, or when more than one person replies. Paid adverts raise the stakes, because each unanswered chat has a cost.

When a slower reply is fine

The five-minute target applies to the first reply. It does not mean rushing the quote.

• Detailed quotes. Reply within five minutes to confirm what you need, give a time for the full quote and meet it. “You will have it by 15:00 tomorrow” is a fast response.
• Event leads. People you met at a trade show expect to hear from you within a day or two. Our guide shows how to follow up trade show leads in 48 hours.
• Questions you cannot answer yet. Say so, say who is finding out and say when you will come back.

A correct answer in 40 minutes is worth more than a wrong one in four. Send the acknowledgement fast and the facts when you have them.

Where a CRM helps

A CRM records the time of every incoming message and every reply, so the weekly measurement takes no effort. It can also send the acknowledgement and alert the owner.

Socianet sends each incoming lead an automatic first reply in about 5 seconds on WhatsApp, SMS or email, and keeps the conversation in one shared inbox with a report of activity per rep. If one person handles all your enquiries from one phone, you do not need it yet.

Frequently asked questions

What is a good lead response time?

Five minutes or less for a reply from a person during working hours, with an automatic acknowledgement within seconds. No study sets an official standard. The 2011 HBR research used one hour as its threshold and the 2007 phone study used five minutes.

What is the five-minute rule for leads?

It is shorthand for the 2007 finding that the odds of reaching a web lead by phone were 100 times lower at 30 minutes than at five. The study covered phone calls at six companies, so treat it as a guide for other channels.

Does an automatic reply count as a response?

It counts as an acknowledgement. It tells the lead the message arrived and when to expect an answer. Measure your response time from the first reply that deals with their question.

How fast should you reply to a WhatsApp enquiry?

Aim for five minutes in working hours. The person usually still has the chat open. On the WhatsApp Business Platform, Meta’s documentation says free-form replies are only allowed inside a 24-hour window from the person’s last message (as of October 2026), so long delays also limit what you can send.

Should you reply to leads at night and at weekends?

Send an automatic acknowledgement at any hour, with your opening times. Have a person reply in the first 30 minutes of the next working day. Add evening cover only if your own numbers show that a large share of enquiries arrive then.

Can you reply too quickly?

A quick reply that answers the question is welcome at any speed. What puts people off is an instant message that ignores what they asked. If you automate the first reply, keep it short and honest about when a person will follow.
