Automate Personalized Email Campaigns with n8n, Twitter & LinkedIn

What This Automation Does

This workflow takes lead info from a Google Sheet and fetches their recent LinkedIn posts and tweets.
It then uses AI to find topics the leads care about and writes a custom email for each.
The workflow sends the email and marks the lead as done to avoid duplicates.
This saves many hours and makes outreach more personal and effective.
