Why teams connect Attio and SendGrid
Sync what happens in SendGrid with the customer records in Attio, 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 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
- Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
- Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
- Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- Run a two-way dual-run when migrating to Attio from another CRM.
Where SendGrid supplies contact or company data
Enriched fields land directly on records in Attio, and refreshes keep them from going stale.
Where SendGrid processes payments
Charges, refunds, and subscription changes appear on the account in Attio, so revenue context lives with the relationship.
Where SendGrid can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Attio sync into SendGrid, so people working there have the context without switching tools.

FAQ
Attio and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and SendGrid: authenticate both systems, choose the objects to sync (such as Attio's People and Companies), 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. Attio: The data model is user-definable: standard objects like people and companies coexist with custom objects, and attributes can be added to any object, so syncs read the schema at runtime. Stacksync's field mapping accounts for these differences between Attio 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 Attio and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Attio and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Attio–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Attio and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Attio: Webhooks on record and list-entry events, with 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.
