Send product updates that stick

Sign up for Resend and verify your sending domain by adding the provided DNS records. Generate an API key in the dashboard. Install the Resend SDK with npm install resend. Test your setup by sending a simple text email to yourself using the SDK's send() method.

Install React Email with npm install @react-email/components. Create an emails/ folder in your project and build a ProductUpdate.tsx template using components like Html, Heading, Text, Button, and Hr. Run npx email dev to preview the template in your browser before sending.

Write a Supabase query to select active users who have not received an update in the past 30 days. Create a Supabase Edge Function that runs on a cron schedule, fetches this user list, renders your React Email template for each recipient, and calls the Resend API to dispatch the emails in batches.
