Send AI upsell emails with Groq, Gmail, HubSpot CRM and Slack alerts

How it works
This workflow monitors user usage via a webhook and automatically triggers an upsell process when limits are exceeded. It formats incoming data, generates a personalized email using AI, and sends it to the user. The workflow then logs the activity in HubSpot and notifies the team via Slack. This ensures timely engagement and improves upgrade conversion rates without manual intervention.
