Why teams connect HubSpot and SendGrid
Sync what happens in SendGrid with the customer records in HubSpot, 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 Owner, Pipeline, Stages, Audit in HubSpot with bi-directional, real-time sync. Activity and record changes in SendGrid update the matching contact or account in HubSpot, and CRM data flows the other way wherever SendGrid can store and use it.
Common use cases
- Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
- Reconcile transactional email activity with support tickets so agents see what a customer was sent
- Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
- Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
Where SendGrid handles support or shared inboxes
Tickets and conversations attach to the right contact and account in HubSpot, so sales sees open issues before the next call.
Where SendGrid runs outreach
Prospects, sends, and replies sync into HubSpot, keeping lead status current without manual imports.
Where SendGrid supplies contact or company data
Enriched fields land directly on records in HubSpot, and refreshes keep them from going stale.

How the HubSpot and SendGrid connectors work
HubSpot
- Integration surface
- REST API (CRM v3)
- Authentication
- OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields
- Change detection
- Records: incremental near-real-time change tracking. Associations: HubSpot has no native association CDC
- Capabilities
- read · write · CDC · webhooks
- Rate limits
- Request limits vary by subscription tier and API type.
SendGrid
- Integration surface
- 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")
- Change detection
- 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
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes

FAQ
HubSpot and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between HubSpot and SendGrid: authenticate both systems, choose the objects to sync (such as HubSpot's Audit and Contact), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for HubSpot and SendGrid: Where SendGrid handles support or shared inboxes; Where SendGrid runs outreach; Where SendGrid supplies contact or company data. Tickets and conversations attach to the right contact and account in HubSpot, so sales sees open issues before the next call.
-
HubSpot: REST API (CRM v3). Authentication: OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields. 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.
-
SendGrid: Suppression lists (bounces, blocks, invalid emails, spam reports, unsubscribe groups) are separate resources from the contact database and must be read explicitly. HubSpot: CDC Boost requires manually creating rollup calculation properties in HubSpot per association table (the unlabeled _label_none rollup is mandatory) and a sync restart to activate. Stacksync's field mapping accounts for these differences between HubSpot 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 HubSpot and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed HubSpot and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom HubSpot–SendGrid integration in-house.
