The cleanest approach is using a Supabase Edge Function as an Auth webhook handler. When a new user is confirmed in Supabase Auth, the Edge Function fires and calls your email platform's API to add the user as a subscriber and enroll them in an onboarding sequence. Alternatively, use Supabase Realtime to watch your users table for new inserts and trigger the enrollment from your backend. Both approaches are reliable; Edge Functions are simpler to maintain.
Yes. Supabase Realtime lets you subscribe to database changes and react to them in your application code. When a user's subscription status changes in your database, a realtime listener can call your email platform's API to apply a tag, move them to a different sequence, or trigger a specific campaign. This is powerful for lifecycle email automation where product events drive email behavior. Make sure your backend handles the realtime events reliably with proper error logging.
Both are excellent choices with slightly different strengths. Resend is the newer option and has become very popular in the Supabase community because it was built by developers and has React email template support and a clean API. Postmark is the more established option with exceptional deliverability track record and detailed analytics. For most Supabase apps, either works well. Resend is the default recommendation in many community guides. Postmark is preferred when you need deep deliverability analytics and have a high-volume sending requirement.
In your Supabase project settings, go to Authentication and then SMTP Settings. Enter the SMTP credentials from your transactional email provider (Resend, Postmark, SendGrid, etc.). Make sure you use the SMTP hostname and port specific to your provider and generate a dedicated API key for this purpose. Test with Supabase's built-in test email feature before going to production. Custom SMTP ensures your auth emails use your domain and benefit from your provider's deliverability infrastructure.
For new users, use a Supabase Edge Function triggered by Auth events to call your email platform's API immediately. For existing users, do a one-time export of your users table (selecting only the email, name, and any relevant attributes) and import it into your email tool. Set up ongoing sync by watching your users table for updates using Supabase's database functions or realtime subscriptions and pushing relevant changes to your email platform's API. This keeps both systems consistent without manual exports.
Track feature usage events in your Supabase database as a user_events table with columns for user_id, event_name, and created_at. Use a Supabase function or Edge Function to watch this table and push events to your email platform. If a user does not trigger a specific feature event within 7 days of signup, send a nudge email. If they do use the feature, skip the nudge and send a more advanced tips email instead. This event-driven approach is far more effective than time-based sequences alone.
