Speed to lead: how fast should you reply to a new enquiry?

By Frenz Adrian Sarabia, founder of G-SYNQ · Updated 28 September 2026

As fast as you can make it without depending on you: an automatic, personal first reply the moment the enquiry arrives, with a link to book a time, then a real conversation as soon as you're free. The reply that waits for you to finish a job, a viewing or a patient is the one that arrives after they've already spoken to someone else.

That's my answer, and I'll explain it. But first I want to be straight about the numbers, because this is a topic where a lot of figures get repeated and very few get checked.

Where do the famous speed-to-lead numbers come from?

You've probably seen claims like "reply within five minutes or the lead is gone", often with a big multiplier attached. Most of them trace back to research published in the Harvard Business Review in March 2011, The Short Life of Online Sales Leads, by James Oldroyd, Kristina McElheran and David Elkington. I opened it. The full article is behind a paywall, and the part I could read says one thing: that most companies are not responding nearly fast enough.

The specific percentages and multipliers that blogs quote from it, I couldn't check against the original, so I won't repeat them here. And even if I could, they'd describe web leads at US companies fifteen years ago, not your enquiries today. So I'll make the case the way I'd make it to a client: by how it actually works.

Why does the first reply matter so much?

Think about what the person was doing when they enquired. They were comparing. A Facebook lead form is prefilled with their name, email and phone, so it takes seconds, and they may have filled in two or three that evening. An enquiry page on your website is the same: they've probably got other tabs open.

At that moment they're paying attention and they remember why they asked. An hour later they're doing something else. The next day, some of them won't remember your business at all. Nothing dramatic happens. The interest just fades, and whoever answered while it was still there is the one who gets the conversation.

Meta says something close to this in its own best practices for responding to leads: minimising the time it takes to follow up can improve your lead quality. It also recommends running lead ads during the hours when you can connect quickly, and asking people when and how they'd like to be reached. Those are Meta's recommendations for its own lead ads, but I think they hold for any enquiry.

Why can't you just reply yourself, quickly?

Because your best enquiries come in when you're busy. The agent is at a viewing. The clinic's front desk is with a patient. The contractor is on a roof. The trainer is running a session. You can be the fastest replier in your industry and still take three hours on a Tuesday, because you were working.

So I split the job in two. The first reply is automatic, personal and immediate, and it gives them something to do straight away, usually a link to book a time. The real conversation is yours, and you have it when you're free, with their details and their answers already in front of you. The automatic part is there to hold their attention until you can take over, not to replace you.

Where does the delay hide in most setups?

When I review how a business handles enquiries, the delay is rarely one big thing. It's usually one of these:

• Leads downloaded by hand. Meta's best practices say manual downloads from Ads Manager can make follow-up take longer, and its page on expired leads says leads can only be downloaded for up to 90 days.
• A sync that isn't instant. Check what your CRM says about its own timing. HubSpot's help page on syncing leads from lead ad forms, for example, says new leads can take up to two hours to sync. In GoHighLevel, which is what I build in, the Facebook Lead Form Submitted trigger starts a workflow when the form is submitted.
• Notifications to an inbox nobody watches. The enquiry arrived on time. It just sat in an email folder.
• Evenings and weekends. The enquiry comes in at 9pm, and the first reply goes out at 10am.
• Separate channels. Website enquiries in one place, lead forms in another, messages in a third, so nobody sees the whole queue.

What should the automatic first reply say?

Short, personal, and about their enquiry. Their first name, what they asked about, who you are in one line, one easy question, and a booking link. Something like this, as an illustration only:

Hi Sam, thanks for your enquiry about [service]. I'm [name] from [business]. What's the best time for a quick call this week? Or you can pick a time that suits you here: [booking link]. I'll reply personally as soon as I'm free.

It shouldn't promise anything you haven't approved, quote prices you haven't agreed, or answer questions that need a professional. In regulated work that matters even more. For clinics I've written separate guides for treatment enquiries in general and for Australian clinics under Ahpra and TGA rules.

Can an automatic reply break any rules?

It can, depending on what it says and where you are. I'm not a lawyer and this isn't legal advice, so check your own situation with an adviser. These are the official sources I work from:

• United States: the FTC's CAN-SPAM compliance guide asks commercial emails for accurate header information, honest subject lines, a valid physical postal address, a clear way to opt out, and opt-outs honored within 10 business days. It treats transactional or relationship messages differently, but says it reads those categories narrowly.
• Australia: the ACMA's guide to avoiding sending spam says you need consent before sending marketing emails or messages, that it's up to you to prove it, and that inferred consent is not as reliable as express consent. That's why, for Australian businesses, I add a consent checkbox to the enquiry form and record who ticked it and when.
• Singapore: for messages to Singapore phone numbers, the PDPC's Do Not Call guide for organisations requires a check against the DNC Registry unless the person has given clear and unambiguous consent. The automatic follow-up I build goes by email, and I don't set up automated texts or WhatsApp messages.

Whatever the market, every automatic message I set up names the business, and one opt-out stops every message.

How do you measure your own speed?

Do it yourself this week. Fill in your own enquiry form and your own lead form, once during working hours and once at night, and time how long it takes to get a reply. Then look at your last twenty enquiries and note when each arrived and when someone first answered. That's your real speed, and it's usually slower than people think.

I'll be honest about our side too. I haven't measured reply times on a live client build and published them, so I'm not going to give you a before-and-after number. What I can tell you is what the system does: it replies to each enquiry straight away and gives you a notification with their details, as described on the services page.
