Why teams connect Seismic and SendGrid

Sync what happens in SendGrid with the customer records in Seismic, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever SendGrid holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Unsubscribe Groups, Email Activity, Contacts, List in SendGrid to Content Versions, Users, User Groups, Teamsites in Seismic with bi-directional, real-time sync. Activity and record changes in SendGrid update the matching contact or account in Seismic, and CRM data flows the other way wherever SendGrid can store and use it.

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 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 04 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.

Common sync patterns

Where SendGrid handles support or shared inboxes

Tickets and conversations attach to the right contact and account in Seismic, so sales sees open issues before the next call.

Where SendGrid runs outreach

Prospects, sends, and replies sync into Seismic, keeping lead status current without manual imports.

Where SendGrid supplies contact or company data

Enriched fields land directly on records in Seismic, and refreshes keep them from going stale.

What you can sync between Seismic 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.

Seismic objects SendGrid objects How this pairing syncs
Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Categories Synced with incremental and full sync per the Stacksync docs. Library Content is specific to Seismic and Categories to SendGrid — each maps to any object or custom field on the other side.
Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Senders Synced with incremental and full sync per the Stacksync docs. Content Versions is specific to Seismic and Senders to SendGrid — each maps to any object or custom field on the other side.
Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Single Sends One-off marketing campaigns whose stats are read back for reporting. Users is specific to Seismic and Single Sends to SendGrid — each maps to any object or custom field on the other side.
User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. User Groups is specific to Seismic and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.
Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Email Activity Synced with incremental and full sync per the Stacksync docs. Teamsites is specific to Seismic and Email Activity to SendGrid — each maps to any object or custom field on the other side.
LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Contacts Marketing recipients upserted from CRM or database records, including custom field values. LiveSend Links is specific to Seismic and Contacts to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Seismic 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.

Seismic SendGrid Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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

SendGrid Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
