Why teams connect Braze and SendGrid
Stop re-entering the same information in Braze and SendGrid: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Campaigns, Canvases, Subscription Groups, Content Blocks in Braze with Single Sends, Unsubscribe Groups, Email Activity, Contacts in SendGrid in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- 01 Sync audience membership computed in the warehouse into Braze segments for targeting.
- 02 Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
- 03 Reconcile transactional email activity with support tickets so agents see what a customer was sent
- 04 Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
Common sync patterns
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
What you can sync between Braze 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.
| Braze objects | SendGrid objects | How this pairing syncs | |
|---|---|---|---|
| Segments Audience definitions read for membership export and campaign targeting. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization. | Categories Synced with incremental and full sync per the Stacksync docs. | Custom Attributes is specific to Braze and Categories to SendGrid — each maps to any object or custom field on the other side. | |
| Custom Events Behavioral events pushed into Braze to trigger campaigns and Canvases. | Senders Synced with incremental and full sync per the Stacksync docs. | Custom Events is specific to Braze and Senders to SendGrid — each maps to any object or custom field on the other side. | |
| Purchases Transaction records logged against profiles for revenue-based targeting. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | Purchases is specific to Braze and Single Sends to SendGrid — each maps to any object or custom field on the other side. | |
| Campaigns Message sends whose metadata and analytics are read for reporting. | Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Campaigns is specific to Braze and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side. | |
| Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis. | Email Activity Synced with incremental and full sync per the Stacksync docs. | Canvases is specific to Braze and Email Activity to SendGrid — each maps to any object or custom field on the other side. |
How changes propagate between Braze 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.
Braze SendGrid Interval-based propagation
DetectionStacksync polls Braze for changes on an incremental schedule, reading only records changed since the previous pass. Braze Currents streams engagement events outward.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
SendGrid Braze 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 Braze through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Braze: Endpoints have per-endpoint rate limits documented by Braze; batch endpoints accept multiple users per request.
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.

FAQ
Braze and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Braze and SendGrid: authenticate both systems, choose the objects to sync (such as Braze's Segments and Custom Attributes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Braze and SendGrid: Handoffs between teams; Where both tools track people or companies: one consistent record; Where one tool produces events: mirror them in the other. When work started in one tool continues in the other, the shared fields travel with it automatically.
-
Braze: REST API. Authentication: REST API keys scoped to specific endpoints, issued per workspace. SendGrid: REST API (v3). Authentication: API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG"). Stacksync manages authentication, retries, and rate limits on both sides.
-
Braze: Profiles can be addressed by external ID, Braze ID, or user aliases, and identity resolution across these matters when merging data from other systems. SendGrid: Contact upserts through the v3 Marketing Campaigns API are asynchronous jobs: the API returns a job ID and processes the batch in the background. Stacksync's field mapping accounts for these differences between Braze 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 Braze and SendGrid records are not retained after a sync operation.
