Why teams connect SendGrid and Unleashed Software

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

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. SendGrid 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Segments, Categories, Senders, Single Sends in SendGrid with Products, Stock On Hand, Sales Orders, Purchase Orders in Unleashed Software 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

  • Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
  • Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
  • Sync Stock On Hand into an ecommerce platform or CRM so quotes and listings reflect real availability.
  • Push Sales Orders from a storefront or CRM into Unleashed for fulfillment without re-keying.

Where SendGrid collects payments: transactions post through

Payment events sync into Unleashed Software as they occur, keeping the enterprise records current without manual entry.

Where Unleashed Software is the HR or people system of record

Worker and organization data from Unleashed Software stays current in SendGrid, 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.
