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.
