use youtube for cold email

Here's something that I have to share with you — especially if you’re into automation, outbound, or just like finding creative ways to get in front of the right people.

May 27, 2025

It started with a simple thought:

What if YouTube wasn’t just a place to post content… but a lead gen engine?

Here’s what I mean

People are literally posting videos about the exact problems we solve — tutorials, tool reviews, "how-to" videos — and just… leaving those sales signals out there in the open.

So we built a system inside n8n that does this:

1. Tracks YouTube for specific keywords

We use Kwatch to monitor new videos with titles like:

→ “Lemlist tutorial”

→ “How to send cold emails”

→ “Smartlead review”

When someone posts that, we know they’re doing outbound and likely need automation help.

You can adjust this for whatever niche you're in — SaaS, ecom, AI, recruiting — just swap in relevant keywords.

2. Scrapes their channel contact info

We grab their public business email using RapidAPI. No guessing, no fake leads — just real creators.

3. Auto-writes a personalized email

We send their video description to ChatGPT, and it comes back with a message like:

“Hey James, just saw your video on Smartlead — loved the breakdown of your sequence strategy. Curious if you've tried automating that with n8n yet?”

(Feels like something you’d actually reply to, right?)

4. Sends the email via Smartlead — on autopilot

Once the message is ready, we push it to Smartlead, with inbox rotation and deliverability built in. You don’t lift a finger after setup.

Why this blew my mind

  • No scraping giant cold lists

  • No guessing who might be interested

  • No boring, generic outreach

Just hyper-relevant, human emails to people already talking about what you do.

Oh — and it runs 24/7. So while you’re working (or sleeping), it’s finding new warm leads in the background.

I recorded a quick video walking through the whole thing.

Hope it gives you ideas — or even better, saves you hours

Let me know what you think if you try it!
