Why teams connect Cin7 and Lemlist

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Lemlist and Cin7.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Purchase orders, Contacts, Branches / locations, Stock adjustments and transfers in Cin7 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

  • Mirror campaign performance data into BI tools for outbound reporting across senders
  • Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • Keep customer records aligned between Cin7 and the CRM to remove duplicate account entry.
  • Write purchase orders created in a planning tool back into Cin7 for receiving.

Master data corrections travel

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

Where Lemlist faces customers and Cin7 carries account records

Order, invoice, or account status from Cin7 appears alongside the customer in Lemlist, so front-line teams answer from live data.

Where Cin7 is the HR or people system of record

Worker and organization data from Cin7 stays current in Lemlist, so the tools people use daily reflect the org as it actually is.
