Why teams connect Resend and TiDB

Mirror Resend's data into TiDB 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 TiDB.

Stacksync mirrors Domains, Email events, API keys, Emails from Resend into Views, Columns, Indexes, Sequences in TiDB 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.
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas
  • Two-way sync between TiDB tables and SaaS tools so operational edits made in either system converge

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 TiDB; join them, index them, and use them in application logic without touching the vendor API.

Automate Resend from your codebase

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

What you can sync between Resend and TiDB

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 TiDB objects
API keys Scoped credentials managed per environment for send and read access. Indexes Secondary indexes that keep incremental sync queries efficient.
Emails Sent messages retrievable by ID with current delivery status. Sequences Server-side ID generation relevant when external systems write rows.
Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Broadcasts One-to-many campaign sends addressed to an audience. Views Logical views for shaping reads before syncing outward.
Domains Verified sending domains with DNS and DKIM status. Columns MySQL-compatible types mapped to fields in the paired system.
