Why teams connect AWS Aurora PostgreSQL and Resend
Mirror Resend's data into AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL.
Stacksync mirrors Audiences, Broadcasts, Domains, Email events from Resend into Rows, Columns, Primary keys and constraints, Views and materialized views in AWS Aurora PostgreSQL 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.
- Feed operational dashboards from a read replica while the writer handles sync traffic.
- Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.
Automate Resend from your codebase
Write to the synced tables in AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL, 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 AWS Aurora PostgreSQL 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.
| AWS Aurora PostgreSQL objects | Resend objects | |
|---|---|---|
| Rows Inserted, updated, and deleted in both directions during bi-directional syncs. | Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. | |
| Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. | Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. | |
| Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. | Broadcasts One-to-many campaign sends addressed to an audience. | |
| Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. | Domains Verified sending domains with DNS and DKIM status. | |
| Foreign keys Relationship metadata that syncs can translate into object references elsewhere. | Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. | |
| Replication slots and publications The logical replication objects that power log-based CDC. | API keys Scoped credentials managed per environment for send and read access. |

FAQ
AWS Aurora PostgreSQL and Resend integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between AWS Aurora PostgreSQL and Resend: authenticate both systems, choose the objects to sync (such as AWS Aurora PostgreSQL's Rows and Columns), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
AWS Aurora PostgreSQL: SQL wire protocol (PostgreSQL-compatible), standard Postgres drivers and JDBC. Authentication: Database credentials, optionally AWS IAM database authentication, over TLS. Resend: REST API. Authentication: API key (Bearer token). Stacksync manages authentication, retries, and rate limits on both sides.
-
Resend: Built by the team behind React Email, so templates are commonly authored as React components rendered to HTML at send time. AWS Aurora PostgreSQL: PostgreSQL compatibility means JSONB, arrays, and custom types survive intact when syncing between Aurora and other Postgres-compatible stores. Stacksync's field mapping accounts for these differences between AWS Aurora PostgreSQL and Resend without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means AWS Aurora PostgreSQL and Resend records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed AWS Aurora PostgreSQL and Resend connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom AWS Aurora PostgreSQL–Resend integration in-house.
-
Yes — Stacksync ships production-grade connectors for both AWS Aurora PostgreSQL and Resend. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
