Short answer
Start by measuring how long your last 30 enquiries waited for a first reply. Then route every channel into one shared queue, send an instant acknowledgement with a booking link, and use AI to draft tailored replies that a staff member approves. Most small teams get faster without hiring because the delay comes from enquiries sitting unseen, not from writing time.
Most slow replies are not caused by a lack of staff. They happen because an enquiry lands in a personal inbox, a Facebook message nobody checks, or a voicemail that waits until Monday. By the time someone sees it, the person has often moved on to whoever answered first.
This article covers what the research on response time actually shows, how to measure your own numbers, and the changes that cut reply time without adding a person to the payroll. Some of them involve AI. Several do not.
How fast should you respond to an enquiry?
Respond as fast as you reliably can during business hours, and aim to acknowledge every enquiry within minutes, even if the full answer comes later. There is no single correct number for every business. A property management company answering rental enquiries competes on minutes. A firm quoting a six-month engineering contract can take a day, as long as the person knows their request was received and when to expect an answer.
The most quoted research is a 2011 Harvard Business Review article, "The Short Life of Online Sales Leads", by James Oldroyd, Kristina McElheran and David Elkington. The authors audited how 2,241 US companies responded to web leads. They reported that many firms were slow, a sizeable share never replied at all, and that companies responding within an hour did much better at reaching a decision-maker than those that waited longer.
Read that study with care. It is 15 years old, it looked at US companies, and the sample leaned toward business-to-business sales. The specific multipliers you see repeated on vendor blogs ("7 times more likely", "60 times more likely") come from secondary summaries; we could not check them against the original, which is paywalled. An older 2007 study often paired with it, which compared calling back within 5 minutes versus 30, was co-run by a sales software company and drew on a small number of firms. We would not plan a business around its numbers.
What holds up is the direction. People who send an enquiry are often contacting several businesses at once, and their interest fades quickly. Faster contact helps. How much it helps in your sector is something you can measure yourself.
Measure your current response time first
Before changing anything, pull your last 30 enquiries and write down two times for each: when it arrived and when a person first replied. Include every channel: website form, email, phone messages, social media messages and Google Business Profile messages. The median of those gaps is your baseline.
Also note how many enquiries never got a reply, and which channel they came through. In our experience, the gaps cluster. One channel is usually the problem, often social messages or after-hours form submissions.
Track two numbers from here on:
- Time to first reply: the median gap between arrival and a human or useful automated response.
- Booked-conversation rate: the share of enquiries that turn into a call, viewing, meeting or quote request.
The second number matters more. A fast reply that does not move the person to a next step is only a faster brush-off.
Get every enquiry into one queue
The biggest single improvement is making sure every enquiry ends up in one place that more than one person can see. When enquiries scatter across the owner's inbox, a shared mailbox, a phone and three social accounts, nobody can tell what is waiting.
That place can be a CRM, a shared inbox, or a simple tracked list. The tool matters less than the rule: every channel forwards into it, every item has an owner, and anything older than your target time is flagged. Most CRMs and shared inbox tools can do this with their built-in forms and integrations. No AI is needed for this step.
Send an instant acknowledgement with a clear next step
An automatic reply that confirms receipt, says when a person will respond, and offers a booking link covers the first few minutes without anyone lifting a finger. Keep it short and specific to the type of enquiry. "Thanks, we got your viewing request for the Quinpool Road unit. You can book a viewing time here, or we'll call you by 3 p.m." is useful. "Your message is important to us" is not.
Booking links do a lot of the work. If the person can choose a time immediately, you have skipped two or three rounds of email.
Where AI helps with enquiry replies
AI is useful once enquiries are captured in one place. It can read an incoming message and draft a tailored first reply using your price list, availability and standard answers, so a staff member reviews and sends it in a minute rather than writing it from scratch. It can also sort enquiries by urgency or fit, and pull names, addresses and details into your CRM fields so nobody retypes them.
Keep a person on the send button for anything that goes to a customer, at least at the start. Drafts from a well-set-up assistant are usually close, but they can state a wrong price or promise a date you cannot meet. If you have already had that problem, our article on why AI chatbots give wrong answers covers the usual causes.
Example: a property management company with 140 units
This is an illustrative example, not a client case. A Halifax property manager gets rental enquiries from a listing site, its own website form, Facebook Marketplace and phone. Two leasing staff share the work around maintenance calls. Their baseline shows most form enquiries get a reply the same day, but Marketplace messages wait over a day and evening enquiries wait until the next afternoon.
The fix has four parts. All four channels forward into the CRM. Each enquiry gets an instant reply naming the unit, the rent and a link to book a viewing slot. An AI assistant drafts a personal follow-up that answers the person's actual questions (pets, parking, move-in date) from the unit's listing details, and a staff member approves it. If the person does not book or reply within two days, one reminder goes out, and the sequence stops as soon as they respond.
The team then compares time to first reply and booked viewings against the baseline after four weeks. That comparison, not a vendor's statistic, tells them whether it worked.
Set up follow-ups that stop when the person replies
Most enquiries that go cold were never followed up. A short sequence of one or two reminders, spaced a few days apart, catches people who meant to reply and forgot. The rule that matters: the sequence must stop the moment the person replies, books or opts out. Nothing damages trust faster than an automated "just checking in" sent after someone already said yes.
Where a person should still handle the reply
Some enquiries should go straight to a person, with no automated draft in the way:
- Quotes and pricing that depend on judgment or site details.
- Complaints, disputes and anything from an unhappy customer.
- Sensitive personal situations, such as health, legal or financial details.
- Large or strategic opportunities where the relationship matters more than the minutes.
Set your sorting rules so these are flagged for a named person immediately. Speed still matters for them; automation is just the wrong tool.
What to do this week
- Pull your last 30 enquiries and record arrival time, first reply time and outcome.
- List every channel enquiries arrive through, including the ones nobody owns.
- Pick one shared place for all enquiries and forward every channel into it.
- Write an instant acknowledgement for your two most common enquiry types, with a booking link.
- Decide which enquiry types always go to a person.
- Set a review date four weeks out to compare first-reply time and booked conversations.
Only after those steps would we add AI-drafted replies. Our article on how to tell whether an AI project worked explains how to run that comparison honestly.

Related questions
What is speed to lead?
Speed to lead is the time between someone sending an enquiry and your business making first contact. The term comes from sales, where research and experience suggest interest fades quickly after a person reaches out. For a small business, the practical measure is the median time from enquiry to first useful reply, tracked across every channel.
What is a good lead response time for a small business?
There is no universal benchmark that applies to every sector. A useful target is an automatic acknowledgement within minutes and a personal reply within a few business hours. Rental, booking and urgent service enquiries need faster replies than complex quotes. Measure your own baseline first, then set a target you can hold consistently.
Can AI reply to customer enquiries on its own?
It can, but we do not recommend fully automatic replies for most small businesses at the start. AI drafts can include wrong prices or promises. A safer setup has AI draft the reply from your approved information and a staff member approve it. Once the drafts are reliably accurate for simple enquiry types, you can consider sending those automatically.
How do I automate follow-up emails without annoying people?
Keep the sequence short, usually one or two reminders a few days apart, and make each one useful rather than a generic check-in. Most importantly, stop the sequence automatically as soon as the person replies, books or unsubscribes. Most CRMs and email tools support this rule, but it has to be switched on and tested.
