How long should you wait to follow up with a lead?

Here's a straightforward question: how quickly do you get back to a new enquiry? Not in theory, not when things are quiet — on a normal Tuesday when you've got a full day and three things already pressing.

For most small businesses, the honest answer is: it depends. Sometimes same day, sometimes the next morning, occasionally longer if something urgent gets in the way. That variability is the problem.

What the research says

A study by Oldroyd et al., published in the Harvard Business Review, tracked lead response times across thousands of companies and found that the odds of qualifying a lead drop dramatically with every hour that passes. Responding within five minutes made a business around 100 times more likely to make contact compared to waiting 30 minutes. That figure has been replicated across multiple studies since, and the principle holds: speed matters far more than most businesses assume.

The reason isn't complicated. When someone fills in a contact form or sends an enquiry, they're usually at the point of highest interest. They've made a decision to reach out. The longer they wait, the more that interest fades — or the more time your competitor has to get there first.

The real problem isn't intent

Most business owners understand this. They intend to respond quickly. The gap between intention and reality comes from the fact that fast follow-up requires someone to be watching for new enquiries consistently, and in a business with a small team, that doesn't always happen. A lead that comes in at 4pm on Friday might not get a response until Monday. By then, the person has probably moved on.

The solution isn't to hire someone to watch your inbox. It's to automate the first response so that every lead gets an acknowledgement immediately — something that confirms you've received their enquiry, sets an expectation for when they'll hear from you properly, and keeps them in the loop. That buys you the time to give a considered reply without losing them in the meantime.

What "following up" actually means

The automated first response is step one. The follow-up sequence after that — the reminder if they don't reply, the check-in after a few days, the final nudge at the end of the week — is where a lot of additional conversions come from, and it's the part almost everyone skips. Velocify's Ultimate Contact Strategy research found that 50% of leads never get a second follow-up attempt at all, yet 93% of converted leads are reached by the sixth attempt. Most businesses send one message and treat silence as a no. The data says silence is usually just silence.

Automating the sequence changes more than convenience. Workato measured lead-routing automation cutting average response time from around 13 hours down to roughly 3 hours 32 minutes. That gap exists because a person has to notice the enquiry before they can act on it, and noticing consistently — every enquiry, every hour of the working day — isn't a discipline problem. It's a workload one.
