Why teams connect Redis Enterprise and Resend
Mirror Resend's data into Redis Enterprise 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 Redis Enterprise.
Stacksync mirrors API keys, Emails, Contacts, Audiences from Resend into Lists, Streams, Pub/Sub channels, Search indexes in Redis Enterprise 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
- Trigger transactional sends when a row changes in an operational database, such as an order status update.
- Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
- Sync Postgres reference tables into RedisJSON documents that power API responses and personalization lookups.
- Publish record-change events into Redis Streams so microservices react to upstream CRM updates without polling.
One integration pattern for the whole stack
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Read Resend with a query
Records from Resend are ordinary rows in Redis Enterprise; 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 Redis Enterprise and Stacksync propagates the change into Resend, replacing custom integration code.
What you can sync between Redis Enterprise 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.
| Redis Enterprise objects | Resend objects | |
|---|---|---|
| Lists Ordered sequences often used as lightweight queues fed by sync events. | API keys Scoped credentials managed per environment for send and read access. | |
| Streams Append-only logs with consumer groups, used to fan sync events out to downstream services. | Emails Sent messages retrievable by ID with current delivery status. | |
| Pub/Sub channels Fire-and-forget messaging used to notify applications when synced keys change. | Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. | |
| Search indexes Secondary indexes (RediSearch) that make synced hashes and JSON documents queryable. | Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. | |
| Keys (Strings) Simple key-value pairs used to cache individual synced records or lookup values. | Broadcasts One-to-many campaign sends addressed to an audience. | |
| Hashes Field-value maps that commonly hold one synced row per hash, keyed by record ID. | Domains Verified sending domains with DNS and DKIM status. |

How the Redis Enterprise and Resend connectors work
Redis Enterprise
- Integration surface
- Redis wire protocol (RESP) via client libraries; separate REST API for cluster management
- Authentication
- Password or ACL-based credentials, typically over TLS
- Change detection
- Keyspace notifications over pub/sub or reads from Redis Streams; no transaction-log CDC surface for data
- Capabilities
- read · write
- Rate limits
- Throughput is bounded by provisioned cluster capacity rather than published API rate limits
Resend
- Integration surface
- REST API
- Authentication
- API key (Bearer token)
- Change detection
- Webhooks for email lifecycle events; polling for contact and audience state

FAQ
Redis Enterprise and Resend integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Redis Enterprise and Resend: authenticate both systems, choose the objects to sync (such as Redis Enterprise's Lists and Streams), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Resend: The send endpoint supports idempotency keys, which matters when a sync pipeline retries requests. Redis Enterprise: Keyspace notifications are delivered over pub/sub with no replay, so reliable change capture usually pairs them with Streams or periodic reconciliation. Stacksync's field mapping accounts for these differences between Redis Enterprise and Resend without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Redis Enterprise and Resend records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Redis Enterprise and Resend connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Redis Enterprise–Resend integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Redis Enterprise and Resend. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Redis Enterprise: Keyspace notifications over pub/sub or reads from Redis Streams; no transaction-log CDC surface for data. On Resend: Webhooks for email lifecycle events; polling for contact and audience state. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
