Why teams connect Resend and Salesmate

Sync what happens in Resend with the customer records in Salesmate, 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 Contacts, Audiences, Broadcasts, Domains in Resend to Deals, Activities, Pipelines and Stages, Products in Salesmate with bi-directional, real-time sync. Activity and record changes in Resend update the matching contact or account in Salesmate, and CRM data flows the other way wherever Resend can store and use it.

Common use cases

  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Sync Salesmate contacts and deals into a Postgres database or warehouse so SMB teams can report outside the CRM.
  • Keep contact segments aligned bi-directionally with an email marketing platform.
