Why teams connect Resend and Scaleway Postgres
Mirror Resend's data into Scaleway Postgres 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 Scaleway Postgres.
Stacksync mirrors Domains, Email events, API keys, Emails from Resend into Tables, Views, Materialized views, Schemas in Scaleway Postgres 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
- Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
- Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
- Sync production tables from Scaleway Postgres into a CRM so sales and support see live product usage on customer records
- Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
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 Scaleway Postgres; 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 Scaleway Postgres and Stacksync propagates the change into Resend, replacing custom integration code.
What you can sync between Resend and Scaleway Postgres
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 | Scaleway Postgres objects | |
|---|---|---|
| Domains Verified sending domains with DNS and DKIM status. | Schemas Namespace tables so multiple applications or environments can be synced selectively. | |
| Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | |
| API keys Scoped credentials managed per environment for send and read access. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | |
| Emails Sent messages retrievable by ID with current delivery status. | Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | |
| Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. | Views Read-only sources for shaping data before it leaves the database. | |
| Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. | Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. |

FAQ
Resend and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Resend and Scaleway Postgres: authenticate both systems, choose the objects to sync (such as Resend's Domains and Email events), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes — Stacksync ships production-grade connectors for both Resend and Scaleway Postgres. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Resend: Webhooks for email lifecycle events; polling for contact and audience state. On Scaleway Postgres: Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Resend side: Domains, Email events, API keys, Emails, plus custom fields where Resend exposes them. On the Scaleway Postgres side: Tables, Views, Materialized views, Schemas. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Resend and Scaleway Postgres: One integration pattern for the whole stack; Read Resend with a query; Automate Resend from your codebase. Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
