Why teams connect Resend and TimescaleDB

Mirror Resend's data into TimescaleDB 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 TimescaleDB.

Stacksync mirrors Email events, API keys, Emails, Contacts from Resend into Hypertables, Chunks, Continuous Aggregates, Regular PostgreSQL Tables in TimescaleDB 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.
  • Sync product or IoT telemetry stored in TimescaleDB into a CRM so account teams see usage metrics next to the customer record.
  • Replicate subscription and billing events from operational Postgres tables into Timescale hypertables for time-series analysis.

Automate Resend from your codebase

Write to the synced tables in TimescaleDB and Stacksync propagates the change into Resend, replacing custom integration code.

React to changes as they happen

Updates in Resend arrive as row changes in TimescaleDB, 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.

What you can sync between Resend and TimescaleDB

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 TimescaleDB objects
API keys Scoped credentials managed per environment for send and read access. Schemas Postgres namespaces used to separate synced datasets by team or environment.
Emails Sent messages retrievable by ID with current delivery status. Hypertables Time-partitioned tables that hold the main time-series data; the primary read and write target in syncs.
Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Chunks Time-bounded partitions of a hypertable; syncs read and write through the parent hypertable and never address chunks directly.
Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Continuous Aggregates Incrementally maintained rollups that serve as pre-aggregated read sources for downstream systems.
Broadcasts One-to-many campaign sends addressed to an audience. Regular PostgreSQL Tables Relational reference data such as devices, tenants, or accounts synced alongside the series data.
Domains Verified sending domains with DNS and DKIM status. Views Standard SQL views used to shape or filter data for consumers.
