Why teams connect Materialize and Resend

Get the data locked inside Resend into Materialize 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 Materialize continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Materialize can also be written back into fields in Resend where the tool can use them.

Common use cases

  • 01 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • 02 Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • 03 Sync operational CRM or ERP data into Materialize so real-time views stay current without batch loads.
  • 04 Read computed view results back into a CRM or application database as derived fields.

Common sync patterns

Where Resend accepts updates: operational write-back

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

History that outlives the tool

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

Analytics on Resend's data

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

What you can sync between Materialize 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.

Materialize objects Resend objects How this pairing syncs
Schemas & Databases Namespaces that organize objects a sync targets. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Schemas & Databases is specific to Materialize and Email events to Resend — each maps to any object or custom field on the other side.
Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines. API keys Scoped credentials managed per environment for send and read access. Tables is specific to Materialize and API keys to Resend — each maps to any object or custom field on the other side.
Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize. Emails Sent messages retrievable by ID with current delivery status. Sources is specific to Materialize and Emails to Resend — each maps to any object or custom field on the other side.
Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Materialized Views is specific to Materialize and Contacts to Resend — each maps to any object or custom field on the other side.
Sinks Outbound connections that emit view changes to Kafka topics. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Sinks is specific to Materialize and Audiences to Resend — each maps to any object or custom field on the other side.
Indexes In-memory arrangements that make view reads fast for serving workloads. Broadcasts One-to-many campaign sends addressed to an audience. Indexes is specific to Materialize and Broadcasts to Resend — each maps to any object or custom field on the other side.

How changes propagate between Materialize and Resend

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.

Materialize Resend Sub-second propagation

DetectionChanges in Materialize are captured at the source via change data capture — no polling loop against its API. SUBSCRIBE queries stream row-level changes of any view or table to the client.

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

Resend Materialize Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.

DeliveryEach detected change is applied to Materialize as a row-level write, with types converted between the two schemas.
