Why teams connect Lemlist and Linnworks

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

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Lemlist 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist with Open Orders, Processed Orders, Stock Items, Stock Levels 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

  • Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • 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 Lemlist faces customers and Linnworks carries account records

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

Where Linnworks is the HR or people system of record

Worker and organization data from Linnworks stays current in Lemlist, 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 Lemlist and Linnworks

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
