Why teams connect Resend and YugabyteDB

Mirror Resend's data into YugabyteDB 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 YugabyteDB.

Stacksync mirrors Emails, Contacts, Audiences, Broadcasts from Resend into Schemas, Sequences, CDC Streams, Databases and Keyspaces in YugabyteDB 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

  • Feed open and click events into a warehouse for engagement analytics alongside product data.
  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.
  • Two-way sync between YugabyteDB application tables and a CRM so product data and account records stay consistent.

Read Resend with a query

Records from Resend are ordinary rows in YugabyteDB; 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 YugabyteDB 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 YugabyteDB, so triggers, jobs, and services can respond in near real time.

What you can sync between Resend and YugabyteDB

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 YugabyteDB objects
Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Broadcasts One-to-many campaign sends addressed to an audience. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Domains Verified sending domains with DNS and DKIM status. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Tables Distributed SQL tables split into tablets; the primary read and write targets.
API keys Scoped credentials managed per environment for send and read access. Indexes Global secondary indexes maintained transactionally alongside table writes.
