Why teams connect Google Cloud Platform and SendGrid

Get the data locked inside SendGrid into Google Cloud Platform as live tables, and send results back where SendGrid can use them, without writing a pipeline.

Whatever SendGrid is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Senders, Single Sends, Unsubscribe Groups, Email Activity from SendGrid into tables in Google Cloud Platform continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Google Cloud Platform can also be written back into fields in SendGrid where the tool can use them.

Common use cases

  • 01 Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
  • 02 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
  • 03 Publish change events to Pub/Sub so downstream services react to record updates as they happen.

Common sync patterns

Cross-tool reporting

Combine SendGrid's data with data from every other synced system to answer questions no single tool can.

Where SendGrid accepts updates: operational write-back

Segments, scores, or reference values computed in Google Cloud Platform sync back onto records in SendGrid, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in Google Cloud Platform preserves a queryable record even as data ages out of SendGrid or gets changed inside it.

What you can sync between Google Cloud Platform 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.

Google Cloud Platform objects SendGrid objects How this pairing syncs
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. List Synced with incremental and full sync per the Stacksync docs. Cloud SQL databases is specific to Google Cloud Platform and List to SendGrid — each maps to any object or custom field on the other side.
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Cloud Storage objects is specific to Google Cloud Platform and Segments to SendGrid — each maps to any object or custom field on the other side.
Pub/Sub topics Event streams used to move change events between systems in near real time. Categories Synced with incremental and full sync per the Stacksync docs. Pub/Sub topics is specific to Google Cloud Platform and Categories to SendGrid — each maps to any object or custom field on the other side.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. Senders Synced with incremental and full sync per the Stacksync docs. Firestore documents is specific to Google Cloud Platform and Senders to SendGrid — each maps to any object or custom field on the other side.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Single Sends One-off marketing campaigns whose stats are read back for reporting. Spanner tables is specific to Google Cloud Platform and Single Sends to SendGrid — each maps to any object or custom field on the other side.
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. BigQuery datasets is specific to Google Cloud Platform and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Platform 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.

Google Cloud Platform SendGrid Sub-second propagation

DetectionGoogle Cloud Platform pushes changes as they happen — webhook events backed by change data capture. Varies by service: log-based CDC on Cloud SQL (logical replication or binlog, also via Datastream), Pub/Sub for event delivery, polling for BigQuery.

DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.

SendGrid Google Cloud Platform 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 Google Cloud Platform as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud Platform: Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own limits.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
