Why teams connect Resend and Streak CRM

Sync what happens in Resend with the customer records in Streak CRM, 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 Emails, Contacts, Audiences, Broadcasts in Resend to Tasks, Email threads, Custom fields, Pipelines in Streak CRM with bi-directional, real-time sync. Activity and record changes in Resend update the matching contact or account in Streak CRM, and CRM data flows the other way wherever Resend can store and use it.

Common use cases

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Keep contacts aligned between Streak and email marketing or enrichment tools
  • Sync Streak boxes into Postgres so operations can query pipeline data with SQL and back internal tools
