n8n workflow · Chapter 2 of 5
Personalized Cold Emailing Sender (Outreach)
Updated · Tested on n8n 1.x · Part of the n8n Lead Generation ebook
Reads each prospect's website and Instagram, has AI write a short personal cold email, checks it for spam and sends it from your Gmail at a human pace.
How this n8n workflow works
- 1Every 15 minutes it picks the next fresh lead
- 2It reads the lead's website and Instagram
- 3AI writes a short personal email
- 4A spam check blocks risky emails
- 5The email is sent from Gmail and logged
Who this workflow is for
- Agencies & freelancers — turn a raw lead list into booked calls without writing every email by hand.
- Founders doing their own sales — sound like you wrote each email personally, at a volume you could never hit manually.
- SDRs / sales teams — automate the first-touch email so reps only jump in once a lead replies.
Why it matters: A generic "spray and pray" cold email gets ignored (and often lands in spam). A genuinely personalized one — that references the prospect's real work — gets replies. Doing that by hand takes 10–15 minutes per lead. This workflow does it in seconds each, safely paced so your domain stays healthy, for a few cents of AI per email.

Common problems and fixes
No email sends, run ends immediately
Why: Daily cap hit, or all leads already in tracker, or the PAUSED switch is set
Fix: Check the tracker for PAUSED; confirm leads have fresh emails not yet in the tracker
Email skipped every time
Why: Lint is failing it (banned word, too long, or a link in body)
Fix: Open the Log Skipped rows — the Lead Status says the exact reason
Emails feel generic
Why: The lead's site returned little/no text (or blocked the fetch)
Fix: Ensure the lead has a real Website; thin sites trigger the AI's NEUTRAL MODE
"Send FAILED" Telegram alert
Why: Gmail quota, auth expired, or bad recipient
Fix: Reconnect the Gmail credential; check Gmail's daily sending limit
Duplicate rows in tracker
Why: Matching column isn't exactly Email
Fix: Both Sheets nodes match on Email — the column must be named exactly that
Two emails to the same company
Why: Per-domain cap only applies per day
Fix: That's by design across days; tighten by lowering dailyCap if needed

How do I get the API keys (WhatsApp, OpenAI and others)?
The ebook includes a setup video for every API and account this workflow needs, so you can get each key step by step without any coding.
Do I need to know coding?
No. Every node, setting, prompt and expression is printed in the ebook, ready to copy-paste, and the workflow JSON can be imported in one click.
