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

  • 01 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
  • 02 Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • 03 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • 04 Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.

Common sync patterns

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.

What you can sync between HubSpot 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.

HubSpot objects SendGrid objects How this pairing syncs
Contact Synced with incremental and full sync per the Stacksync docs. Contacts Marketing recipients upserted from CRM or database records, including custom field values. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Product Synced with incremental and full sync per the Stacksync docs. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Product is specific to HubSpot and Segments to SendGrid — each maps to any object or custom field on the other side.
Ticket Synced with incremental and full sync per the Stacksync docs. Categories Synced with incremental and full sync per the Stacksync docs. Ticket is specific to HubSpot and Categories to SendGrid — each maps to any object or custom field on the other side.
Quote Synced with incremental and full sync per the Stacksync docs. Senders Synced with incremental and full sync per the Stacksync docs. Quote is specific to HubSpot and Senders to SendGrid — each maps to any object or custom field on the other side.
Goal Synced with incremental and full sync per the Stacksync docs. Single Sends One-off marketing campaigns whose stats are read back for reporting. Goal is specific to HubSpot and Single Sends to SendGrid — each maps to any object or custom field on the other side.
Owner Synced with incremental and full sync per the Stacksync docs. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. Owner is specific to HubSpot and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between HubSpot 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.

HubSpot SendGrid Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

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

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

Rate-limit considerations

  • HubSpot: Request limits vary by subscription tier and API type.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
