I built 10 free n8n workflows for social media automation and lead generation

I've been building n8n automation workflows for over a year, and I recently packaged my most useful ones into free collections. Here's what I built and how.

The Problem

Every solo founder or small team I know wastes 3-5 hours/week on repetitive tasks:

  • Manually scraping leads from LinkedIn/Google Maps
  • Scheduling social media posts one by one
  • Sending follow-up emails that all say the same thing
  • Cleaning and sorting email lists

These are all solved problems — but most solutions cost $50-200/month for SaaS tools that lock your data and workflows behind their UI.

n8n changes this. Self-hosted, open source, visual automation. The workflows run on your server for $5/month.

What I Built

Pack 1: Social Media Automation (5 workflows)

01 — Twitter/X AI Auto-Poster
Reads from Google Sheets → generates tweets with GPT-4o-mini → posts every 6 hours. Cost: ~$0.001/tweet.

02 — Reddit Lead Scraper

Monitors any subreddit for keywords → GPT-4o-mini scores each post 1-10 → sends hot leads to Telegram.

03 — Email Outreach Automator
Reads contacts from Airtable → generates personalized openers with GPT-4o-mini → sends via Gmail → logs replies.

04 — Content Repurposer
One blog post → 5 social formats (Twitter thread, LinkedIn, Instagram caption, Facebook, newsletter).

05 — Instagram DM Autoresponder
Detects story mentions → sends personalized AI replies.

Pack 2: Lead Generation (5 workflows)

01 — LinkedIn Lead Scraper + AI Qualifier
Google Search API → finds LinkedIn profiles → GPT-4o-mini scores each lead (company size, role, fit) → only 7+ leads reach your sheet.

02 — Website Visitor Identifier
Captures IPs → resolves company info via geolocation → AI analyzes sales potential.

03 — CRM Auto Follow-Up
Reads CRM contacts → identifies no-reply in 3/7/14 days → sends personalized follow-ups.

04 — Google Maps Scraper
Google Places API → AI qualifies each business → appends leads with contact info.

05 — Email List Cleaner
Deduplicates → removes invalid → AI segments into hot_lead/warm_lead/newsletter/low_priority.

The Stack

  • n8n (self-hosted on Hetzner CX22 = $4.15/month)

  • Google Sheets as free database
  • Caddy for automatic HTTPS

Total infra cost: ~$5/month.

How to Import

  1. Download the ZIP, extract the JSON files
  2. In n8n: Menu → Import from File → select the .json
  3. Add your API keys (OpenAI, Google Sheets)
  4. Activate the workflow

No coding required. Each workflow runs in under 30 seconds.


If you find these useful, I'm building more. The next pack will cover Notion integrations and automated email sequences.
