How fast should you reply to a new lead?

What the research says The most quoted study on this is "The Short Life of Online Sales Leads", published in Harvard Business Review in March 2011 by James Oldroyd, Kristina McElheran and David Elkington. Here's what it found (SmartCompany summary):

The researchers sent test enquiries to 2,241 US companies. Only 37% responded within an hour. Among companies that responded within 30 days, the average response time was 42 hours. Firms that contacted a lead within an hour were nearly seven times as likely to qualify it (meaning a meaningful conversation with a decision maker) as firms that waited an hour longer. They were more than 60 times as likely to qualify it as firms that waited 24 hours or more.

Two honest caveats. The study is from 2011, and it looked at US companies. But if anything, buyers are less patient now, not more. And the core finding matches what I see every week with UK coaches and consultants.

Why speed matters so much When someone downloads your guide or fills in your form, you have their attention. They're thinking about the problem right now. An hour later they're on to the next thing. A day later they've forgotten which form they filled in, and they may already be talking to someone else.

The business that replies first, and personally, usually gets the conversation. That's why worse businesses often win: not because they're better, but because they turned up first.

The out-of-hours problem Here's what makes this hard. Leads don't arrive when you're at your desk.

In one client's data, covering 192 leads over six days, 86% arrived outside Monday to Friday, 9 to 5. Sixty-three came in before 8am. Forty-eight arrived at the weekend. If that business only replied in office hours, most of its leads would have waited until the next working day.

You can't be on your phone at 6am on a Sunday. Nor should you be.

Fast isn't enough. It has to be useful. A "Thanks for your enquiry, we'll be in touch" auto-reply is fast, but it doesn't count. It doesn't start a conversation, and the lead knows it's a robot.

A good first reply does three things:

1. Acknowledges what they did. "Thanks for grabbing the guide." 2. Gives them something useful. The link, a tip, or the answer to the question they're likely to have. 3. Asks one easy question. "What made you download it?" or "Are you planning a launch soon?"

That third part is where the qualifying starts. The answer tells you who needs a resource, who needs time and who needs to talk to you today.

How to reply fast without living on your phone The answer is roughly 80% automation and 20% human, and the 20% is where the sale happens. Automation handles the first reply, the useful resource and the first question, at any hour. A person steps in when the lead is ready to talk, asks something tricky or needs reassurance.

WhatsApp works well for this because people read and reply to it like they would a friend, and an AI conversation trained on how you speak can handle the first exchange in your tone. If you're worried about sounding robotic, read will automated WhatsApp messages make you sound like a bot?.

A simple speed-to-lead checklist Every new lead gets a personal reply within five minutes, day or night The first reply asks one easy question

Ready buyers are flagged and handed to a person the same day Someone owns the human follow-up, with a named backup for holidays You track time to first reply and time to booked call, not just lead volume

What this won't fix Speed won't save a weak offer or the wrong audience. It gives good leads the best chance. It doesn't create them.
