Why teams connect Folk CRM and Resend

Sync what happens in Resend with the customer records in Folk 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 Audiences, Broadcasts, Domains, Email events in Resend to Custom fields, Notes, Reminders, People in Folk CRM with bi-directional, real-time sync. Activity and record changes in Resend update the matching contact or account in Folk CRM, 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.
  • Keep folk and a billing or customer success tool aligned on company records as deals close.
  • Sync folk people and companies with a marketing or outbound tool so outreach lists stay current.
