Ever feel like writing emails every week is a full-time job you never applied for?
Yeah, same.
So when I saw Mario Aldayuz (Head of Partnerships at HL Pro Tools) demo an N8N-powered workflow that builds weekly emails for you, I basically fist-pumped my coffee across the room. ☕💥
Let me walk you through what he showed us—because if you’re juggling subaccounts, campaigns, and still copy-pasting emails manually… this might just blow your mind. 🤯
The Premise: Smarter Emails, Less Work
Here’s the setup Mario walked through:
📥 Input: An RSS feed pulling fresh blog content
🧠 Middle Layer: OpenAI/Claude to generate subject lines + email copy
📤 Output: Fully formatted HTML emails ready to send through HighLevel
It’s like hiring a marketing assistant—only it runs 24/7, doesn’t call in sick, and costs less than your daily DoorDash order.
What Actually Happened?
Mario built a scheduled workflow in N8N that did all this:
- Pulled blog posts from an RSS feed
- Processed the copy using Markdown-to-HTML conversion
- Fed it into OpenAI for subject lines and punchier body text
- Pushed the output into HighLevel using API calls
Oh—and it all runs without touching a button.
Key Idea: This workflow doesn’t just automate. It upgrades your marketing while you sleep.
What Broke (and How He Fixed It)
Because nothing worth building works the first time…
HighLevel’s API documentation decided to play hide-and-seek.
Especially around creating and saving email templates programmatically.
But Mario? He’s been through the API trenches. He mapped out how to use N8N’s HTTP modules + some manual testing to make everything run smooth.
Pro Tip: When in doubt, hit the API directly—just don’t expect hand-holding from the docs.
Why You Should Care
If you’re running an agency or building inside HighLevel, here’s why this matters:
✅ Zapier’s too expensive (we’ve seen $20k+ monthly bills 🤯)
✅ N8N is open-source, self-hosted, and scales like a champ
✅ Email is still one of the highest ROI marketing tools—but only if you use it consistently
So instead of spending hours building weekly newsletters…
Let AI + N8N + HighLevel do it for you.
You just approve the final version and hit send. Or better yet—don’t even do that. 😎
Real Talk: Automation Isn’t Just About Time
Yeah, automations save time. But the real win?
They let you do things you literally couldn’t afford before.
Like consistent, personalized content at scale. Or launching campaigns that run across 10+ subaccounts with zero manual effort. That’s the unlock.
