Why teams connect Reltio and SendGrid
Mirror SendGrid's data into Reltio 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 Reltio.
Stacksync mirrors Contacts, List, Segments, Categories from SendGrid into Crosswalks, Interactions, Matches (Potential Matches), Activity Log in Reltio 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
- 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 Push cleansed, deduplicated golden records and survivorship results from Reltio back into CRM and ERP systems so every app works from the mastered record.
- 04 Sync Relations (affiliations, hierarchies, households) between Reltio and a CRM or graph so account and affiliation structures stay aligned.
Common sync patterns
Automate SendGrid from your codebase
Write to the synced tables in Reltio 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 Reltio, so triggers, jobs, and services can respond in near real time.
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.
What you can sync between Reltio 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.
| Reltio objects | SendGrid objects | How this pairing syncs | |
|---|---|---|---|
| Crosswalks Per-entity references to the source systems and their record IDs; written when loading records so Reltio ties each source contribution to a golden record, and read to trace lineage back to origin systems. | Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Crosswalks is specific to Reltio and Contacts to SendGrid — each maps to any object or custom field on the other side. | |
| Interactions Transactional or event records linked to entities (purchases, visits, activities); read and written via /interactions to enrich profiles and power 360-degree reporting. | List Synced with incremental and full sync per the Stacksync docs. | Interactions is specific to Reltio and List to SendGrid — each maps to any object or custom field on the other side. | |
| Matches (Potential Matches) Candidate duplicate pairs produced by match rules; read to review, and resolved with merge, unmerge, or not-a-match actions to control survivorship. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Matches (Potential Matches) is specific to Reltio and Segments to SendGrid — each maps to any object or custom field on the other side. | |
| Activity Log Immutable audit trail of changes to entities and relations via /activities; read-only, used for history, lineage, and compliance reporting. | Categories Synced with incremental and full sync per the Stacksync docs. | Activity Log is specific to Reltio and Categories to SendGrid — each maps to any object or custom field on the other side. | |
| Data Change Requests (DCR) Stewardship change proposals routed through approval workflows; read and written to feed or track governed edits to golden records. | Senders Synced with incremental and full sync per the Stacksync docs. | Data Change Requests (DCR) is specific to Reltio and Senders to SendGrid — each maps to any object or custom field on the other side. | |
| Reference Data (RDM) Managed lookup and reference values (country codes, standardized values, hierarchies); read and updated so downstream systems share consistent reference data. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | Reference Data (RDM) is specific to Reltio and Single Sends to SendGrid — each maps to any object or custom field on the other side. |
How changes propagate between Reltio 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.
Reltio SendGrid Interval-based propagation
DetectionStacksync polls Reltio for changes on an incremental schedule, reading only records changed since the previous pass. Polling the REST API on updateTime (epoch-ms), for example filter=gt(updateTime,<timestamp>), for entities and relations changed past a stored.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
SendGrid Reltio 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 Reltio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Reltio: Reltio applies per-tenant API throttling and returns HTTP 429 (Too Many Requests) when limits are exceeded; there is no single fixed request-per-second cap published for all tenants, and throttling is tuned per tenant and environment. Large loads and reads use bulk create/update and the asynchronous export/jobs API rather than row-by-row calls.
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.

How the Reltio and SendGrid connectors work
Reltio
- Integration surface
- Reltio REST API (Data API) — /entities, /relations, /interactions, /activities, plus Match, RDM (reference data), and Data Change Request endpoints; base URL https://{environment}.reltio.com/reltio/api/{tenantId}
- Authentication
- OAuth 2.0 bearer tokens obtained from Reltio's central auth server (POST https://auth.reltio.com/oauth/token, client-credentials or password grant, application/x-www-form-urlencoded) and sent as Authorization: Bearer <token>; access tokens expire after about 60 minutes and are renewed with a refresh token, and are scoped per API (entities_api, relations_api, interactions_api, configuration_api, graphs_api)
- Change detection
- Polling the REST API on updateTime (epoch-ms), for example filter=gt(updateTime,<timestamp>), for entities and relations changed past a stored watermark. Reltio has no CDC log external tools consume; separately, Reltio's event streaming can publish entity change events (created, changed, removed) to a customer-configured message queue (Amazon SQS/SNS, Google Pub/Sub, Azure Service Bus, or Kafka), which is a queue feed rather than HTTP webhooks.

FAQ
Reltio and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Reltio and SendGrid: authenticate both systems, choose the objects to sync (such as Reltio's Crosswalks and Interactions), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
SendGrid: Email Activity access requires an add-on subscription in SendGrid; without it the Email Activity API is not available. Reltio: Reltio tenants are environment- and region-specific: the REST base URL is https://{environment}.reltio.com/reltio/api/{tenantId}, so the host and tenant ID must match where the tenant is provisioned. Stacksync's field mapping accounts for these differences between Reltio 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 Reltio and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Reltio and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Reltio–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Reltio and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Reltio: Polling the REST API on updateTime (epoch-ms), for example filter=gt(updateTime,<timestamp>), for entities and relations changed past a stored watermark. Reltio has no CDC log external tools consume; separately, Reltio's event streaming can publish entity change events (created, changed, removed) to a customer-configured message queue (Amazon SQS/SNS, Google Pub/Sub, Azure Service Bus, or Kafka), which is a queue feed rather than HTTP webhooks. 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.
