Why teams connect AWS S3 and SendGrid
Get the data locked inside SendGrid into AWS S3 as live tables, and send results back where SendGrid can use them, without writing a pipeline.
Whatever SendGrid 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 Activity, Contacts, List, Segments from SendGrid into tables in AWS S3 continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in AWS S3 can also be written back into fields in SendGrid where the tool can use them.
Common use cases
- 01 Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
- 02 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
- 03 Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.
- 04 Trigger incremental sync runs from S3 event notifications when new files land in a prefix.
Common sync patterns
Analytics on SendGrid's data
Records and events from SendGrid land in AWS S3 as queryable tables, current within seconds and ready to join with the rest of the warehouse.
Cross-tool reporting
Combine SendGrid's data with data from every other synced system to answer questions no single tool can.
Where SendGrid accepts updates: operational write-back
Segments, scores, or reference values computed in AWS S3 sync back onto records in SendGrid, putting analysis where the work happens.
What you can sync between AWS S3 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.
| AWS S3 objects | SendGrid objects | How this pairing syncs | |
|---|---|---|---|
| Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Access Points is specific to AWS S3 and Segments to SendGrid — each maps to any object or custom field on the other side. | |
| Multipart Uploads The mechanism used to write large export files reliably. | Categories Synced with incremental and full sync per the Stacksync docs. | Multipart Uploads is specific to AWS S3 and Categories to SendGrid — each maps to any object or custom field on the other side. | |
| Buckets Top-level containers a sync targets; region and policy are set at this level. | Senders Synced with incremental and full sync per the Stacksync docs. | Buckets is specific to AWS S3 and Senders to SendGrid — each maps to any object or custom field on the other side. | |
| Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | Objects is specific to AWS S3 and Single Sends to SendGrid — each maps to any object or custom field on the other side. | |
| Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. | Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Prefixes is specific to AWS S3 and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side. | |
| Object Metadata System and user-defined metadata read alongside object contents. | Email Activity Synced with incremental and full sync per the Stacksync docs. | Object Metadata is specific to AWS S3 and Email Activity to SendGrid — each maps to any object or custom field on the other side. |
How changes propagate between AWS S3 and SendGrid
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.
AWS S3 SendGrid Sub-second propagation
DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
SendGrid AWS S3 Sub-second propagation
DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.
DeliveryEach detected change is written to AWS S3 through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.

How the AWS S3 and SendGrid connectors work

FAQ
AWS S3 and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between AWS S3 and SendGrid: authenticate both systems, choose the objects to sync (such as AWS S3's Access Points and Multipart Uploads), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
SendGrid: Email Activity data retention depends on subscription level (typically 7 days by default, 30 days with the add-on). AWS S3: S3 provides strong read-after-write consistency for all operations, so newly written objects are immediately readable by a sync. Stacksync's field mapping accounts for these differences between AWS S3 and SendGrid 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 AWS S3 and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed AWS S3 and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom AWS S3–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both AWS S3 and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on AWS S3: S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback. On SendGrid: 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. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
