An n8n agent replies to cold-email leads in 90 seconds and booked 9 extra sales calls
In plain words
An n8n agent reads replies to cold emails and answers with a tailored reply and a booking link, carrying on the thread until the lead books or says no.
What happened: Replies in under 90 seconds instead of 3–6 hours, and 9 extra good leads in 2 weeks (their own figures).
These numbers come from the builder and haven't been checked independently.

- 1
Export recent replies to your cold emails.
- 2
Sort them: interested, question, not now, no.

Build an n8n agent that reads new replies and uses the prompt below.
- 4
Have it draft only for a week, then let it send.
- 5
Track meetings booked per 100 replies.
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)
A prospect replied to our email: [reply]. If interested or asking a question, answer briefly and share [booking link]. If 'not now', ask when to follow up. If clearly no, thank them and stop. Under 70 words.
[Highlighted] = replace with your own details before you run it.
What you should get back: "Great question — setup takes about a week and you keep your current CRM. Grab a slot here: [link]."
