Why teams connect Gladly and Resend

Sync what happens in Resend with the customer records in Gladly, 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 Resend 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 API keys, Emails, Contacts, Audiences in Resend to Conversation items, Agents, Topics, Tasks in Gladly with bi-directional, real-time sync. Activity and record changes in Resend update the matching contact or account in Gladly, and CRM data flows the other way wherever Resend can store and use it.

Common use cases

  • Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • Feed open and click events into a warehouse for engagement analytics alongside product data.
  • Sync Gladly customer profiles with an order database so agents see purchase history and profile updates flow back.
  • Mirror conversations and topics into a warehouse for CX analytics and staffing models.
