The Estate Agent Whose AI Was Too Fast: Why Timing is Part of the Copy

I spoke to an estate agent today who’s been using AI for their outreach. It’s working well — good writing, relevant follow-ups, clearly trained on solid examples.

But people kept emailing back asking: “Are you actually a real person?”

Not because the writing was bad. Because the response was too fast.

The Tell

No real person replies to an email in 4 seconds at 8pm on a Tuesday. That timestamp is a signal — one people read even when they don’t realise they’re reading it.

The AI was doing everything right except one thing: it was responding on machine time, not human time.

The Fix: Randomised Delay

This is something I’ve already built into my own cold email automation — a randomised delay on auto-responses.

Not a fixed “wait 5 minutes.” A randomised window. Because humans don’t respond on a schedule. We’re unpredictable. We get distracted, we pick up the phone, we reply when we get a moment — sometimes 3 minutes later, sometimes 7.

Building that unpredictability into your automation makes it feel real.

The Formula (n8n)

Here’s what I use in an n8n Wait node:

{{ Math.floor(Math.random() * 61) + 180 }}

This generates a random number between 180 and 240 — giving you a delay of 3 to 4 minutes.

Long enough to feel like a human had a moment to read and respond. Short enough to still be timely and relevant.

One line of code. Massive difference in how it lands.

Timing is Part of the Copy

In outbound automation, timing sends a message before the words do. It’s a layer of communication that most people aren’t thinking about.

A few things worth building into any AI outreach setup:

• Randomise send times — not always on the hour or half hour
• Vary response delays — use a formula like the one above instead of a fixed wait
• Respect time zones — don’t trigger a reply at 3am to a 2:59am email
• Build in human-shaped pauses — especially for multi-step sequences

The goal isn’t to deceive anyone. It’s to not accidentally signal “bot” when you’re genuinely trying to be helpful and responsive.

One Formula, One Node, Sorted

The estate agent asked me how to fix it. One formula. One n8n Wait node. Five minutes of implementation.

Small details like this are the difference between automation that converts and automation that gets flagged.
