Why teams connect Scaleway Postgres and SendGrid
Mirror SendGrid'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 SendGrid 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 Unsubscribe Groups, Email Activity, Contacts, List from SendGrid into Views, Materialized views, Schemas, Sequences 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 SendGrid, so the tool and the database never disagree.
Common use cases
- 01 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
- 02 Reconcile transactional email activity with support tickets so agents see what a customer was sent
- 03 Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
- 04 Replicate the application database into a warehouse for analytics without writing custom pipelines
Common sync patterns
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 SendGrid with a query
Records from SendGrid are ordinary rows in Scaleway Postgres; join them, index them, and use them in application logic without touching the vendor API.
Automate SendGrid from your codebase
Write to the synced tables in Scaleway Postgres and Stacksync propagates the change into SendGrid, replacing custom integration code.
What you can sync between Scaleway Postgres and SendGrid
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.
| Scaleway Postgres objects | SendGrid objects | How this pairing syncs | |
|---|---|---|---|
| Views Read-only sources for shaping data before it leaves the database. | Categories Synced with incremental and full sync per the Stacksync docs. | Views is specific to Scaleway Postgres and Categories to SendGrid — each maps to any object or custom field on the other side. | |
| Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | Senders Synced with incremental and full sync per the Stacksync docs. | Materialized views is specific to Scaleway Postgres and Senders to SendGrid — each maps to any object or custom field on the other side. | |
| Schemas Namespace tables so multiple applications or environments can be synced selectively. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | Schemas is specific to Scaleway Postgres and Single Sends to SendGrid — each maps to any object or custom field on the other side. | |
| Sequences Generate primary keys; sync tooling must respect them when writing rows. | Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Sequences is specific to Scaleway Postgres and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side. | |
| Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | Email Activity Synced with incremental and full sync per the Stacksync docs. | Columns is specific to Scaleway Postgres and Email Activity to SendGrid — each maps to any object or custom field on the other side. | |
| Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Tables is specific to Scaleway Postgres and Contacts to SendGrid — each maps to any object or custom field on the other side. |
How changes propagate between Scaleway Postgres and SendGrid
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Scaleway Postgres SendGrid Sub-second propagation
DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
SendGrid Scaleway Postgres Sub-second propagation
DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.
DeliveryEach detected change is applied to Scaleway Postgres as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.

FAQ
Scaleway Postgres and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Scaleway Postgres and SendGrid: authenticate both systems, choose the objects to sync (such as Scaleway Postgres's Views and Materialized views), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
SendGrid: Contact upserts through the v3 Marketing Campaigns API are asynchronous jobs: the API returns a job ID and processes the batch in the background. Scaleway Postgres: It runs the standard PostgreSQL engine, so ordinary Postgres drivers, ORMs, and SQL tooling work unmodified; managed-service restrictions apply to some server-level features. Stacksync's field mapping accounts for these differences between Scaleway Postgres and SendGrid 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 Scaleway Postgres and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Scaleway Postgres and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Scaleway Postgres–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Scaleway Postgres and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Scaleway Postgres: Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling. On SendGrid: Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
