I almost paid $2k for this. built it free

You’re still writing cold emails one by one.

Your competitor has a bot doing 100 before breakfast.

Here’s the exact workflow. It’s free. No code needed. Takes 15 minutes to set up.

Six weeks ago I was quoted $2,100 to build a basic cold email automation.

The agency wanted to charge me for Instantly, Clay, and three hours of “custom workflow development.”

I said no. Opened n8n. Broke it twice. Rebuilt it.

Third attempt — every node lit up green, drafts hit my Gmail, subject lines were sharp. Total cost: $0.

• Reads lead data directly from your Google Sheet

• Passes each lead to Groq AI for instant email generation

• Writes a personalized subject line for every single contact

• Saves each email as a Gmail draft — ready to review and send

• Runs the whole sequence automatically, start to finish

Here’s the reality:

What agencies charge $2K+ for… you can build for $0.

• n8n (workflow automation)
→ $0 (self-hosted or free cloud)

• Groq API (AI model)
→ $0 (free tier, extremely fast)

• Google Sheets (lead database)
→ $0

• Gmail (email delivery)
→ $0

• Clay / Instantly / custom dev
→ usually $2,100+
→ you can skip all of it

I ran it on 2 leads to test. Two Gmail drafts appeared within seconds.

Subject lines: “AI Solutions” and “Growing ApexQuant.” Both relevant. Both ready to send.

Scale that to 200 leads. Same effort. Same time. Same $0.
