Why teams connect Amazon Seller Central and SendGrid

Flow Amazon Seller Central data into SendGrid in real time — no exports, no schedulers, no custom scripts.

Amazon Seller Central is a read-only source: Stacksync reads its data in real time and delivers it into SendGrid, so SendGrid always reflects the current state of Amazon Seller Central — without exports, scripts, or schedulers.

Sellers connect Amazon Seller Central to SendGrid to drive transactional and lifecycle email from real marketplace activity. Amazon Orders and Shipments become the triggers and audience data behind SendGrid Contacts and Segments, so messaging reflects what buyers actually purchased and when it shipped.

Stacksync syncs Shipments, Financial Events, Returns, Reports in Amazon Seller Central with Single Sends, Unsubscribe Groups, Email Activity, Contacts in SendGrid in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • 01 Segment repeat buyers vs first-time buyers in SendGrid using synced Amazon Orders history.
  • 02 Correlate SendGrid Email Activity with subsequent Amazon Orders to judge campaign impact.
  • 03 Keep sender programs organized: SendGrid Senders and Categories aligned to marketplace product lines.
  • 04 Track price and inventory report changes across marketplaces from one queryable table.

Common sync patterns

Buyer list building

Amazon Orders populate SendGrid Contacts and Lists so purchase history drives audience membership.

Shipment-triggered messaging

Amazon Shipments events trigger SendGrid sends, with Email Activity tracked per order.

Product-based segmentation

Order Items and Listings / Catalog Items map to SendGrid Segments and Categories for targeted campaigns.

What you can sync between Amazon Seller Central 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.

Amazon Seller Central objects SendGrid objects How this pairing syncs
FBA Inventory Fulfillable quantity by SKU, synced out for stock planning and replenishment. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. FBA Inventory is specific to Amazon Seller Central and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.
Shipments Inbound and outbound shipment records used to track fulfillment state. Email Activity Synced with incremental and full sync per the Stacksync docs. Shipments is specific to Amazon Seller Central and Email Activity to SendGrid — each maps to any object or custom field on the other side.
Financial Events Settlement, fee, and refund events synced to finance systems for reconciliation. Contacts Marketing recipients upserted from CRM or database records, including custom field values. Financial Events is specific to Amazon Seller Central and Contacts to SendGrid — each maps to any object or custom field on the other side.
Returns Return and refund records routed to support and finance workflows. List Synced with incremental and full sync per the Stacksync docs. Returns is specific to Amazon Seller Central and List to SendGrid — each maps to any object or custom field on the other side.
Reports Asynchronous bulk exports used for large reads (orders, inventory, settlements). Segments Query-based contact groups whose membership SendGrid computes from contact fields. Reports is specific to Amazon Seller Central and Segments to SendGrid — each maps to any object or custom field on the other side.
Feeds Asynchronous bulk write channel for price, inventory, and listing updates. Categories Synced with incremental and full sync per the Stacksync docs. Feeds is specific to Amazon Seller Central and Categories to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Amazon Seller Central 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.

Amazon Seller Central SendGrid Interval-based propagation

DetectionStacksync polls Amazon Seller Central for changes on an incremental schedule, reading only records changed since the previous pass. Historical and incremental syncs (mechanism not further specified).

DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.

SendGrid Amazon Seller Central 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.

DeliveryAmazon Seller Central does not accept inbound record writes, so this direction carries requests rather than records: Amazon Seller Central's output flows back as field updates on the originating SendGrid records.

Rate-limit considerations

  • Amazon Seller Central: Per-operation token-bucket rate limits; bulk reads and writes should go through the asynchronous Reports and Feeds APIs instead of item-by-item calls.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
