Why teams connect MongoDB and SendGrid

Mirror SendGrid's data into MongoDB 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 SendGrid 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 MongoDB.

Stacksync mirrors Email Activity, Contacts, List, Segments from SendGrid into Collections, Documents, Embedded documents and arrays, Indexes in MongoDB 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 SendGrid, so the tool and the database never disagree.

Common use cases

  • Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
  • Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
  • Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.

Read SendGrid with a query

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

Automate SendGrid from your codebase

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

React to changes as they happen

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

What you can sync between MongoDB and SendGrid

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.

MongoDB objects SendGrid objects
Documents BSON records created, updated, and deleted during syncs, keyed by _id. Senders Synced with incremental and full sync per the Stacksync docs.
Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Single Sends One-off marketing campaigns whose stats are read back for reporting.
Indexes Keep lookups by sync key fast on large collections. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs.
Views Read-only aggregation-defined sources for filtered sync datasets. Email Activity Synced with incremental and full sync per the Stacksync docs.
Change streams The oplog-backed event feed that powers real-time change capture. Contacts Marketing recipients upserted from CRM or database records, including custom field values.
GridFS files Chunked file storage whose metadata can be referenced by synced documents. List Synced with incremental and full sync per the Stacksync docs.
What ships with MongoDB ⇄ SendGrid

Connect MongoDB and SendGrid for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every MongoDB–SendGrid connection.

Real-time

Two-way sync

Changes in MongoDB or SendGrid instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever MongoDB or SendGrid data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single MongoDB or SendGrid record.

Observability

Monitoring

Track your MongoDB ⇄ SendGrid sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between MongoDB and SendGrid.

How the MongoDB and SendGrid connectors work

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities
read · write · CDC
MongoDB setup guide

SendGrid

Integration surface
REST API (v3)
Authentication
API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
Change detection
Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling
Capabilities
read · write · webhooks
Rate limits
Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes
