Why teams connect Attio and SendGrid

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

Attio and SendGrid connect so the CRM drives email audiences and the email layer reports back: Attio People and Companies feed SendGrid Contacts, Lists, and Segments, while Email Activity flows back onto CRM records. Marketing sends from clean, current CRM data, and sales sees engagement without opening SendGrid.

Stacksync connects Segments, Categories, Senders, Single Sends in SendGrid to People, Companies, Users, Deals in Attio with bi-directional, real-time sync. Activity and record changes in SendGrid update the matching contact or account in Attio, and CRM data flows the other way wherever SendGrid can store and use it.

Common use cases

  • 01 Suppress SendGrid sends to accounts with an open Attio Deal in negotiation by syncing deal-stage segments.
  • 02 Flag bounced SendGrid Contacts back on Attio People so reps stop using dead addresses.
  • 03 Build SendGrid Segments from Attio Company attributes instead of maintaining separate marketing lists.
  • 04 Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting

Common sync patterns

Audience sync

Attio People sync to SendGrid Contacts and populate Lists and Segments based on CRM attributes like deal stage.

Engagement on the record

SendGrid Email Activity syncs back to the matching Attio Person so opens, clicks, and bounces are visible in the CRM.

Sender and category hygiene

SendGrid Senders and Categories map to Attio Custom objects for tracking which programs touch which accounts.

What you can sync between Attio 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.

Attio objects SendGrid objects How this pairing syncs
People Standard person object; synced with marketing tools and warehouse person tables. Contacts Marketing recipients upserted from CRM or database records, including custom field values. People is specific to Attio and Contacts to SendGrid — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. List Synced with incremental and full sync per the Stacksync docs. Companies is specific to Attio and List to SendGrid — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Users is specific to Attio and Segments to SendGrid — each maps to any object or custom field on the other side.
Deals Pipeline records; read out for revenue reporting and written to from automation. Categories Synced with incremental and full sync per the Stacksync docs. Deals is specific to Attio and Categories to SendGrid — each maps to any object or custom field on the other side.
Workspaces Synced with incremental and full sync per the Stacksync docs. Senders Synced with incremental and full sync per the Stacksync docs. Workspaces is specific to Attio and Senders to SendGrid — each maps to any object or custom field on the other side.
Custom objects Workspace-defined objects that behave like standard ones in the API. Single Sends One-off marketing campaigns whose stats are read back for reporting. Custom objects is specific to Attio and Single Sends to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Attio 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.

Attio SendGrid Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

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

Rate-limit considerations

  • Attio: Subject to the platform's published API rate limits.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
