Supabase Auth → Welcome Sequence + CRM Pipeline

Connect your Supabase-powered app to your CRM and communication stack the moment a user signs up. This workflow listens for new Supabase Auth signups (via database webhook or polling), enriches the user profile, sends a branded welcome email through Resend or SendGrid, creates or updates a HubSpot contact with signup metadata, posts a celebratory Slack notification to your team channel, and logs the signup to a Google Sheets tracker for weekly reporting. Includes conditional branching: trial users get onboarding tips; paid users get a personal thank-you from the founder.
