Why teams connect BigQuery and SendGrid

Get the data locked inside SendGrid into BigQuery 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 List, Segments, Categories, Senders from SendGrid into tables in BigQuery continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in BigQuery can also be written back into fields in SendGrid where the tool can use them.

Common use cases

  • Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule

Where SendGrid accepts updates: operational write-back

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

History that outlives the tool

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

Analytics on SendGrid's data

Records and events from SendGrid land in BigQuery as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between BigQuery 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.

BigQuery objects SendGrid objects
Projects Connection scope: the service account grants access per project. Senders Synced with incremental and full sync per the Stacksync docs.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Single Sends One-off marketing campaigns whose stats are read back for reporting.
Partitioned tables Synced like regular tables; partition columns map to target fields. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs.
Clustered tables Supported; clustering is transparent to the sync. Email Activity Synced with incremental and full sync per the Stacksync docs.
Datasets Organizational container — you pick which dataset’s tables to sync. Contacts Marketing recipients upserted from CRM or database records, including custom field values.

How the BigQuery and SendGrid connectors work

BigQuery

Integration surface
GoogleSQL via the BigQuery REST API, client libraries, JDBC/ODBC drivers, and the Storage Read/Write APIs
Authentication
Google Cloud service account: create a dedicated service account, grant roles (BigQuery Data Editor, BigQuery Job User, Cloud Functions Service Agent, Cloud Run Developer, Eventarc Event Receiver
Change detection
Real-time notification service deployed into your Google Cloud project: Eventarc ("a notification service that enables real-time updates to happen") with a Cloud Run "secure portal for real-time notification service in
Capabilities
read · write · CDC
Rate limits
Subject to Google Cloud quotas on queries, DML, and streaming; DML is supported but the platform favors append-heavy batch and streaming loads over row-at-a-time writes
BigQuery setup guide

SendGrid

Integration surface
REST API (v3)
Authentication
API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
Change detection
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
Capabilities
read · write · webhooks
Rate limits
Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes
