Why teams connect Lemlist and Snapfulfil
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Lemlist and Snapfulfil.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Activities, Unsubscribes, Webhooks, Team Members in Lemlist with Inventory balances, Shipments, Warehouse locations, Returns in Snapfulfil 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
- 01 Stop or pause sequences automatically when a reply converts to a deal in the CRM
- 02 Mirror campaign performance data into BI tools for outbound reporting across senders
- 03 Mirror fulfillment activity into a database for operational reporting outside the WMS
- 04 Push sales orders from an ERP or e-commerce platform into Snapfulfil for fulfillment without file drops

How changes propagate between Lemlist and Snapfulfil
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Lemlist Snapfulfil Sub-second propagation
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.
DeliveryEach detected change is written to Snapfulfil through its API, with automatic retries and rate-limit backoff.
Snapfulfil Lemlist Interval-based propagation
DetectionStacksync polls Snapfulfil for changes on an incremental schedule, reading only records changed since the previous pass. Polling, subject to the platform's API rate limits.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
