Send personalized SaaS welcome emails with Stripe, Pinecone, GPT-4o, and Gmail

Who it's for SaaS founders and developers who want to automate their customer onboarding experience from payment to welcome email, without any manual work. How it works - A Stripe Trigger listens for successful payment events. - The payment amount is converted and used to identify the subscription tier. - Customer details are extracted from the Stripe payload. - The AI Agent queries Pinecone to retrieve the correct plan details and generates a personalised HTML welcome email with the renewal date calculated automatically. - The email is parsed and sent via Gmail. Customer details and subscription info are logged to Google Sheets for renewal tracking. Set up steps - Connect your Stripe account and point it to listen for checkout.session.completed events. - Store your tier information as chunks in Pinecone. - Add your OpenAI credentials for the AI Agent and Embeddings nodes. - Connect Gmail as your sending account. Create a Google Sheet with columns: Name, Email, Amount, Tier, Renewal Date, Status. Requirements - Stripe account - Pinecone account with tier knowledge base uploaded - OpenAI account - Gmail account - Google Sheets
