Why teams connect RavenDB and Resend
Mirror Resend's data into RavenDB 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 RavenDB.
Stacksync mirrors API keys, Emails, Contacts, Audiences from Resend into Time series, Data subscriptions, Documents, Collections in RavenDB 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
- 01 Feed open and click events into a warehouse for engagement analytics alongside product data.
- 02 Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
- 03 Mirror reference data from relational systems into RavenDB collections that serve application reads.
- 04 Consolidate documents from distributed RavenDB clusters into one reporting store.
Common sync patterns
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 RavenDB; 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 RavenDB and Stacksync propagates the change into Resend, replacing custom integration code.
What you can sync between RavenDB 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.
| RavenDB objects | Resend objects | How this pairing syncs | |
|---|---|---|---|
| Attachments Binary payloads stored with documents, handled separately from the JSON body | Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. | Attachments is specific to RavenDB and Audiences to Resend — each maps to any object or custom field on the other side. | |
| Revisions Historical versions of documents, useful for audit-oriented replication | Broadcasts One-to-many campaign sends addressed to an audience. | Revisions is specific to RavenDB and Broadcasts to Resend — each maps to any object or custom field on the other side. | |
| Counters Numeric values attached to documents that change independently of the document body | Domains Verified sending domains with DNS and DKIM status. | Counters is specific to RavenDB and Domains to Resend — each maps to any object or custom field on the other side. | |
| Time series Timestamped measurements stored per document, synced for metrics analysis | Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. | Time series is specific to RavenDB and Email events to Resend — each maps to any object or custom field on the other side. | |
| Data subscriptions Server-side change feeds that push matching documents to consumers | API keys Scoped credentials managed per environment for send and read access. | Data subscriptions is specific to RavenDB and API keys to Resend — each maps to any object or custom field on the other side. | |
| Documents JSON records, the primary unit read and written during sync | Emails Sent messages retrievable by ID with current delivery status. | Documents is specific to RavenDB and Emails to Resend — each maps to any object or custom field on the other side. |
How changes propagate between RavenDB 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.
RavenDB Resend Sub-second propagation
DetectionChanges in RavenDB are captured at the source via change data capture — no polling loop against its API. Data subscriptions and the Changes API provide server-pushed change feeds.
DeliveryEach detected change is written to Resend through its API, with automatic retries and rate-limit backoff.
Resend RavenDB Sub-second propagation
DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.
DeliveryEach detected change is written to RavenDB through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- RavenDB: Throughput bounded by cluster resources rather than API quotas.

FAQ
RavenDB and Resend integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between RavenDB and Resend: authenticate both systems, choose the objects to sync (such as RavenDB's Attachments and Revisions), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Resend side: API keys, Emails, Contacts, Audiences, plus custom fields where Resend exposes them. On the RavenDB side: Time series, Data subscriptions, Documents, Collections. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for RavenDB and Resend: One integration pattern for the whole stack; Read Resend with a query; Automate Resend from your codebase. Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
-
RavenDB: HTTP REST API with official clients (.NET, Java, Node.js, Python, and others). Authentication: X.509 client certificates on secured servers, instead of username and password. Resend: REST API. Authentication: API key (Bearer token). Stacksync manages authentication, retries, and rate limits on both sides.
-
Resend: Webhook payloads cover the full email lifecycle (sent, delivered, bounced, complained, opened, clicked) and are signed for verification. RavenDB: Data subscriptions deliver a resumable, reliable stream of documents matching a query, which fits continuous sync without external CDC tooling. Stacksync's field mapping accounts for these differences between RavenDB and Resend without custom code.
