An n8n workflow personalised 900 cold emails and booked 10 meetings

In plain words

An n8n workflow pulled company signals like funding, new hires or launches, and added 1-2 personal lines to each email.

What happened: 900 emails, 6% replied, and 10 good meetings booked (their own figures).

These numbers come from the builder and haven't been checked independently.

How to do it yourself

Our suggested steps. The company didn't publish theirs.

  1. 1

    Pick a narrow list of companies.

  2. 2

    Pull a recent signal for each (funding, hire, launch).

  3. 3

    Use the prompt below to write the opening lines.

  4. 4

    Send 10-20 a day per inbox.

  5. 5

    Track replies and change one thing at a time.

The instructions to give the AI

Paste this into ChatGPT (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.

This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.

Agent instructions (prompt)

[Company] recently [signal]. Write 2 opening lines for a cold email that mention this naturally and connect it to [problem we solve]. Under 35 words. No hype.

[Highlighted] = replace with your own details before you run it.

What you should get back: "Congrats on the new Austin office. Hiring 10 reps at once usually makes onboarding messy — we help with that."
