Sales response time: why the first hour matters
A Harvard Business Review study of 2,241 firms and 1.25 million leads: responding within an hour makes qualifying a lead many times more likely.
When a prospect shows interest, reaching them within the first hour is many times more effective than reaching them a few hours later. The finding comes from one of the most cited studies in sales. So how fast are companies in reality?
The study: the short life of online sales leads
The 2011 Harvard Business Review article by James Oldroyd, Kristina McElheran and David Elkington has two parts.
1. How fast do firms respond? The researchers submitted test inquiries through the websites of 2,241 US companies and timed the replies:
| Response time | Share of companies |
|---|---|
| Within 1 hour | 37% |
| 1–24 hours | 16% |
| More than 24 hours | 24% |
| Never responded | 23% |
2. How much does speed matter? A separate analysis covered 1.25 million sales leads received by 29 B2C and 13 B2B companies. Firms that tried to contact a lead within an hour were:
- nearly 7 times as likely to qualify the lead (have a meaningful conversation with a decision maker) as firms that tried one hour later,
- more than 60 times as likely as firms that waited 24 hours or longer.
Note: Figures such as “100x more likely within 5 minutes” that are often attributed to this article come from an earlier, separate study by the same researcher. This article uses only the HBR figures.
Why this matters for outbound
The study looked at inbound inquiries such as web forms. In outbound the same moment exists: when a prospect replies to your cold email or LinkedIn message, their interest is at its peak.
In international sales that moment is easier to miss:
- Time zones: When a London buyer replies in the afternoon, the working day in Istanbul may be over. For the US, the gap is 7–11 hours.
- Liability of foreignness: A foreign supplier already carries more question marks. A slow reply reinforces the feeling that “this company isn’t close enough to us”.
- Competitor speed: The buyer may be talking to a local supplier the same week.
What to do
- Set a response-time target. Aim to answer positive replies within one hour during business hours, and measure it.
- Work in your target market’s hours. Whoever monitors replies should overlap with the buyer’s working day.
- Keep the next step ready. A calendar link, a short intro and two time options, so the thread stays short.
- Reply quickly to “no” as well. A fast, polite close keeps the door open for later.
