Why teams connect Affinity and SendGrid

Sync what happens in SendGrid with the customer records in Affinity, 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 Categories, Senders, Single Sends, Unsubscribe Groups in SendGrid to List Entries, Persons, Organizations, Opportunities in Affinity with bi-directional, real-time sync. Activity and record changes in SendGrid update the matching contact or account in Affinity, 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
  • Sync notes and reminders into project or task systems used outside the deal team.
  • Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.

Where SendGrid supplies contact or company data

Enriched fields land directly on records in Affinity, and refreshes keep them from going stale.

Where SendGrid processes payments

Charges, refunds, and subscription changes appear on the account in Affinity, so revenue context lives with the relationship.

Where SendGrid can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Affinity sync into SendGrid, so people working there have the context without switching tools.
