Why teams connect Resend and SingleStore

Mirror Resend's data into SingleStore so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Resend through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in SingleStore.

Stacksync mirrors Domains, Email events, API keys, Emails from Resend into Views, Reference Tables, Pipelines, Stored Procedures in SingleStore and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Resend, so the tool and the database never disagree.

Common use cases

  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Consolidate data from transactional databases and SaaS apps into one store that handles both lookups and scans.
  • Keep reference data consistent between SingleStore and application databases.

Read Resend with a query

Records from Resend are ordinary rows in SingleStore; join them, index them, and use them in application logic without touching the vendor API.

Automate Resend from your codebase

Write to the synced tables in SingleStore and Stacksync propagates the change into Resend, replacing custom integration code.

React to changes as they happen

Updates in Resend arrive as row changes in SingleStore, so triggers, jobs, and services can respond in near real time.

What you can sync between Resend and SingleStore

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.

Resend objects SingleStore objects
Domains Verified sending domains with DNS and DKIM status. Views Read-only projections used as curated sync sources.
Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
API keys Scoped credentials managed per environment for send and read access. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Emails Sent messages retrievable by ID with current delivery status. Stored Procedures Existing logic sometimes invoked on write paths.
Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys.
Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Databases The connection target containing the tables a sync addresses.
