Why teams connect Amazon RDS and Resend

Mirror Resend's data into Amazon RDS 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 Amazon RDS.

Stacksync mirrors Emails, Contacts, Audiences, Broadcasts from Resend into Primary and Unique Keys, Read Replicas, Stored Procedures, Databases in Amazon RDS 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

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Bi-directional sync between an RDS database and a CRM so application data and sales data stay consistent without custom integration code
  • Mirror SaaS objects into RDS tables so product features can join business data with application data in one query

React to changes as they happen

Updates in Resend arrive as row changes in Amazon RDS, 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 Amazon RDS; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Amazon RDS and Resend

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.

Amazon RDS objects Resend objects
Stored Procedures Engine-specific logic that can react to synced rows. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Databases Engine-level databases on the instance that scope a sync's reads and writes. Broadcasts One-to-many campaign sends addressed to an audience.
Schemas Namespaces within a database used to isolate synced tables. Domains Verified sending domains with DNS and DKIM status.
Tables The core sync target; rows map to records in connected SaaS systems. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Views Read-side projections exposed to outbound syncs. API keys Scoped credentials managed per environment for send and read access.
Columns Field-level mapping targets, typed per the underlying engine. Emails Sent messages retrievable by ID with current delivery status.
