Why teams connect Outreach and SendGrid
Sync what happens in SendGrid with the customer records in Outreach, 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 Senders, Single Sends, Unsubscribe Groups, Email Activity in SendGrid to Calls, Tasks, Opportunities, Users in Outreach with bi-directional, real-time sync. Activity and record changes in SendGrid update the matching contact or account in Outreach, 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
- Suppress prospects across systems when a contact unsubscribes or a customer churns.
- Enroll leads in sequences automatically by writing sequence-state records when a lead crosses a scoring threshold in the warehouse.
Where SendGrid supplies contact or company data
Enriched fields land directly on records in Outreach, and refreshes keep them from going stale.
Where SendGrid processes payments
Charges, refunds, and subscription changes appear on the account in Outreach, so revenue context lives with the relationship.
Where SendGrid can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Outreach sync into SendGrid, so people working there have the context without switching tools.

FAQ
Outreach and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Outreach and SendGrid: authenticate both systems, choose the objects to sync (such as Outreach's Users and Mailboxes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 Outreach and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Outreach and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Outreach–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Outreach and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Outreach: Webhook subscriptions on resource create, update, and destroy events, plus polling. 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.
-
On the SendGrid side: Senders, Single Sends, Unsubscribe Groups, Email Activity, plus custom fields where SendGrid exposes them. On the Outreach side: Calls, Tasks, Opportunities, Users. Stacksync auto-detects both schemas and converts types between the two systems.
