Reply in an hour, win the job

Harvard Business Review's lead response research (Oldroyd, 2011) found that companies replying to an inbound enquiry within an hour are seven times more likely to qualify that lead than those who reply more than two hours later. Seven times. Not seven per cent better. Seven times.

Across the businesses we assess, the median first-reply time to a new enquiry during the working day is 4 hours 12 minutes. Factor in evenings, weekends, and the Friday-to-Monday gap, and the number climbs above 14 hours. For a service business where inbound enquiry is the primary source of new work, that gap is costing jobs.

The surprising part: nobody in most businesses is tracking it. First-reply time is invisible in almost every analytics setup. The leak is real and completely unmeasured.

Why the obvious fix is the wrong one

The instinctive response to "we reply too slowly" is "we should type faster" or "someone should watch the inbox more carefully". Both treat the symptom. The root cause is usually one of three things: the enquiry arrives at the wrong time with no system for what happens next; the person who should reply does not have a ready answer and parks it; or the reply feels like significant work and gets treated as a task to sit down and do. None of those are solved by trying harder.

The four-step fix sequence

Step 1: Visibility - track it for a fortnight

Before fixing the problem, measure it. For two weeks, note the time each new enquiry arrives and the time you send the first response. At the end of the fortnight, you will have a real number rather than a guess, and a pattern - a specific time, day, or enquiry type where the delay is worst.

The free email response time benchmark tool puts your number against UK industry medians and gives a rough estimate of the conversion impact. Useful as a before-and-after baseline.

Step 2: Saved replies for your four most common enquiry types

Most inbound enquiries to a UK service business are variations on the same four or five questions: how much, how long, what is included, are you available, can we have a quick call. The reason these take time is not because the answer is complicated - it is because writing a fresh response from scratch every time takes mental effort. That turns a 3-minute task into a 20-minute one you keep deferring.

Saved replies in Gmail or Outlook reduce each response to a 90-second job: open the template, adjust the two or three lines that need personalising, send. No new tools required. The three prompts post includes a template for using ChatGPT or Claude to draft the initial saved replies - about 15 minutes to produce drafts you refine to your own voice.

Step 3: AI drafting for the non-standard enquiries

For enquiries that do not fit a saved reply, AI drafting removes the blank-page delay. Paste the enquiry into ChatGPT or Claude with a short prompt: "Draft a reply to this enquiry. We do [what you do]. Cover [the key points asked]. Keep it to three short paragraphs." The output will need editing, but starting from a 70% draft is consistently faster than starting from nothing.

The important discipline: generate the draft while you are still in the email. If the process requires switching applications or coming back later, the speed advantage disappears. Open the enquiry, generate the draft, edit and send.

Step 4: Automation - only at the end

The last step, not the first, is an automated confirmation that acknowledges receipt and sets an expectation: "We will come back to you within a few hours." This handles the Friday-to-Monday gap - an enquiry that receives an immediate acknowledgement is more likely to still be engaged on Monday than one that sat in silence all weekend. A simple Zapier or Make workflow between your contact form and email system handles this. The configuration takes under an hour and the return is permanent.

Automation on top of a working reply process is a force multiplier. Automation on top of a slow, inconsistent process just sends the acknowledgement faster while the actual reply stays delayed.

A worked example

A four-person letting agency had an average first-reply time of just over 6 hours for viewing enquiries arriving by email. The diagnosis: two staff covered replies, neither checked email during viewings, and Friday afternoons were consistently slow.

The fix: three saved replies for the most common enquiry types, a Monday morning 15-minute inbox check added to the diary, and a basic auto-acknowledgement for out-of-hours enquiries. Average first-reply time dropped to 38 minutes. The principal reported a noticeable lift in viewings booked from same-day enquiries within a fortnight. No new tools. No technical work. A day in total.

For letting agents, the competition for a prospective tenant's attention is real-time - they are often enquiring to three or four properties simultaneously and will book with the first agent who replies. The letting agent admin cost breakdown covers reply speed as part of the wider picture of where admin hours go and what the conversion cost looks like.

The broader point

First-reply time is the single most under-managed conversion variable in most UK service businesses. The fix, in the right sequence, does not require a new tool or a reorganised team. It requires saved replies, a fortnight of measurement, and the discipline to treat a new enquiry as something to handle now.
