Why teams connect BigQuery and Resend

Get the data locked inside Resend into BigQuery as live tables, and send results back where Resend can use them, without writing a pipeline.

Whatever Resend 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 Emails, Contacts, Audiences, Broadcasts from Resend 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 Resend where the tool can use them.

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.
  • 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

Cross-tool reporting

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

Where Resend accepts updates: operational write-back

Segments, scores, or reference values computed in BigQuery sync back onto records in Resend, 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 Resend or gets changed inside it.

What you can sync between BigQuery 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.

BigQuery objects Resend objects
Partitioned tables Synced like regular tables; partition columns map to target fields. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Clustered tables Supported; clustering is transparent to the sync. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Datasets Organizational container — you pick which dataset’s tables to sync. Broadcasts One-to-many campaign sends addressed to an audience.
Projects Connection scope: the service account grants access per project. Domains Verified sending domains with DNS and DKIM status.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
