7 Overlooked Delays to Fix Before Your Next Inbound Lead Goes Cold

By Ashish Aman · 19 August 2026 · 8 min read

Speed to lead measures how fast someone replies to an inbound enquiry. It does not measure whether the buyer got an answer. A four-minute reply that offers a meeting on Thursday has not resolved anything — it has scheduled the resolution for three days later. Marklinea calls the number that actually matters speed to resolution: the time from enquiry to the buyer having the answer they came for.

What is speed to lead?

Speed to lead is the elapsed time between an inbound enquiry — a demo request, a form fill, a pricing enquiry — and the first response from the seller. Most B2B teams track it as a service-level target, commonly five minutes, and report it on a weekly dashboard.

The metric became standard because of a single piece of research. In 2007, Dr James Oldroyd's Lead Response Management study, run with InsideSales, found that contacting a lead within five minutes rather than thirty made contact roughly 100 times more likely and qualification about 21 times more likely.

That study is now nineteen years old. It predates the iPhone.

The other pillars are barely younger. Harvard Business Review's The Short Life of Online Sales Leads — the source of the widely quoted 42-hour average response time, and the finding that 23% of companies never respond at all — was published in 2011. Drift's survey, which found only 7% of companies replied within five minutes and 55% did not reply within five business days, ran in 2018.

What does speed to lead fail to measure?

Speed to lead stops its clock when the seller sends something. It does not ask what that something contained.

In practice, the first response to an inbound demo request is usually an email offering three time slots. That is a fast reply and a completed SLA. It is not an answer. The buyer wanted to know whether the product does the specific thing they need, roughly what it costs, and whether it works with the stack they already run. A calendar invite answers none of it.

So the dashboard turns green while the buyer waits.

There is a second problem worth naming, because it undermines the whole category. The single most-quoted statistic in speed-to-lead marketing — that 78% of customers buy from the vendor who responds first — has no traceable primary source. It is variously credited to McKinsey, Forrester, InsideSales and MIT. The attributions contradict each other, and the McKinsey study does not appear to exist.

Marklinea has cited that figure on its own website. We are removing it. A number nobody can trace is not evidence, however often it is repeated.

What is speed to resolution?

The two numbers can be minutes apart or weeks apart, and nothing on a standard sales dashboard distinguishes them.

A team can reply in four minutes and resolve in four days. Another can reply in an hour and resolve in the same hour, because whoever replied could actually answer the question. The second team wins the deal, and by the first metric it looks slower.

Marklinea uses speed to resolution because it is the only one of the two the buyer experiences. Nobody has ever chosen a vendor because the acknowledgement email arrived quickly.

How does speed to resolution differ from speed to lead?

The gap between the two columns is where deals are lost, and almost nobody measures it.

What are the seven delays before an answer?

Seven separate handoffs sit between a form submission and a human answering a real question. A faster first reply removes one of them.

Fill in the right-hand column for your own funnel. Most teams have never added it up.

Steps 1 to 5 are invisible on most dashboards. Step 6 is the one everybody optimises. Step 7 is the one the buyer cares about, and on most teams it lands days after step 1.

How do you measure speed to resolution?

You do not need new tooling. You need one honest pass over the last twenty inbound enquiries.

1. Take the last 20 inbound enquiries. Not a sample you like — the last 20.
2. Record the timestamp of the enquiry. Form submission, first email, whichever started it.
3. Record the timestamp of the first substantive answer — the moment a human addressed what the buyer actually asked. A meeting invitation does not count. A brochure does not count.
4. Subtract. That is speed to resolution for that enquiry.
5. Compare it to your speed-to-lead number for the same twenty. The difference between the two averages is the number this article is about.
6. Count the ones where step 3 never happened. These are usually the largest group and the most uncomfortable.

Do this for twenty enquiries and you will know more about your funnel than the dashboard has told you all year.

Why can't a human team respond fast enough?

The gap is structural, not a discipline problem. Blaming the AE misreads it entirely.

An enquiry that arrives at 9pm on a Sunday cannot be answered at 9pm on a Sunday by someone who is not working. An enquiry that arrives at the same moment as nineteen others cannot be answered immediately by one person. A question about a specific integration cannot be answered by whoever is on rota if they do not know the answer.

Every good team eventually arrives at the same three tools: an SLA, a round-robin, and a chatbot. The SLA speeds up step 6. The round-robin reshuffles step 4. The chatbot deflects the easy questions and hands the real ones to step 6 anyway.

None of them changes step 7, because step 7 needs someone who can hold a real conversation, available at the moment the buyer asked. That is a coverage problem, and coverage is the one thing headcount solves expensively and badly.

What changes about the first sales conversation?

If resolution is the metric, the first conversation has to happen at the moment of enquiry rather than after it. That is the whole change, and everything else follows from it.

It means the first conversation is not a qualification call in disguise. A buyer who asked a question and got asked eight questions back has not been resolved. It means whoever takes it needs to answer, not route — including showing the integration, the pricing page, the security document, whatever was actually asked for.

And it means the meeting stops being the goal and becomes the outcome. A buyer whose questions were answered in the first sixty seconds books a meeting because they want one, not because it was the only thing on offer.

Marklinea built Chloe to take that first conversation — on the page, in about thirty seconds, at whatever hour the enquiry arrives.
