Stop manually sending follow-ups. This workflow automates your entire cold email outreach with AI-powered personalization, smart scheduling, and automatic reply detection.

✨ What It Does

This workflow sends a perfectly-timed 3-email sequence to B2B prospects with:

AI-generated personalized emails** adapted to each prospect's sector, company size, and role
Smart scheduling**: Only sends Tuesday/Wednesday/Thursday at optimal times (~9AM with randomization)

Spam prevention**: Randomized sending times, professional intervals
Full tracking**: Updates Google Sheets with send status and reply detection
