Why teams connect Resend and SAP

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and SAP.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Resend is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Audiences, Broadcasts, Domains, Email events in Resend with Inventory / Stock, Cost Centers, Business Partners, Materials (Products) in SAP bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

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.
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

Where Resend faces customers and SAP carries account records

Order, invoice, or account status from SAP appears alongside the customer in Resend, so front-line teams answer from live data.

Where SAP is the HR or people system of record

Worker and organization data from SAP stays current in Resend, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

What you can sync between Resend and SAP
