Why teams connect Resend and Supabase

Mirror Resend's data into Supabase so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Resend through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Supabase.

Stacksync mirrors Audiences, Broadcasts, Domains, Email events from Resend into Row Level Security Policies, JSONB Columns, Database Functions, Storage Object Metadata in Supabase and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Resend, so the tool and the database never disagree.

Common use cases

  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
  • Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record

React to changes as they happen

Updates in Resend arrive as row changes in Supabase, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Resend with a query

Records from Resend are ordinary rows in Supabase; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Resend and Supabase

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Resend objects Supabase objects
Domains Verified sending domains with DNS and DKIM status. Storage Object Metadata File metadata rows that can be joined to synced application data.
Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Tables Standard Postgres tables; the primary two-way sync target.
API keys Scoped credentials managed per environment for send and read access. Views Read-side projections exposed to outbound syncs.
Emails Sent messages retrievable by ID with current delivery status. Schemas Namespaces (public and custom) that scope sync access.
Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. auth.users Managed authentication users, often mirrored into CRM or support systems.
Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Row Level Security Policies Row-level access rules that govern what the REST layer exposes.
