Why teams connect Linnworks and SendGrid

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Contacts, List, Segments, Categories in SendGrid with Purchase Orders, Suppliers, Channel Listings, Returns & Refunds in Linnworks 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 contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
  • Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
  • Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock

Where SendGrid faces customers and Linnworks carries account records

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

Where SendGrid collects payments: transactions post through

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

Where Linnworks is the HR or people system of record

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