Why teams connect Azure Synapse Analytics and Resend

Get the data locked inside Resend into Azure Synapse Analytics 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 Email events, API keys, Emails, Contacts from Resend into tables in Azure Synapse Analytics continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Azure Synapse Analytics can also be written back into fields in Resend where the tool can use them.

Common use cases

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Consolidate SaaS data alongside lake data so analysts join both through one SQL surface.
  • Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.

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 Azure Synapse Analytics sync back onto records in Resend, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in Azure Synapse Analytics preserves a queryable record even as data ages out of Resend or gets changed inside it.

What you can sync between Azure Synapse Analytics 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.

Azure Synapse Analytics objects Resend objects
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Broadcasts One-to-many campaign sends addressed to an audience.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Domains Verified sending domains with DNS and DKIM status.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Views Curated projections used when downstream tools should not read base tables directly. API keys Scoped credentials managed per environment for send and read access.
Schemas Namespaces that separate staging, integration, and presentation layers. Emails Sent messages retrievable by ID with current delivery status.
