Why teams connect Lemlist and Syspro
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Lemlist and Syspro.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Suppliers, Inventory items, Sales orders, Purchase orders in Syspro 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
- Extract job and WIP data into a warehouse for production and costing reports
- Post shipment confirmations from logistics systems back against SYSPRO sales orders
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 Syspro carries account records
Order, invoice, or account status from Syspro appears alongside the customer in Lemlist, so front-line teams answer from live data.
Where Syspro is the HR or people system of record
Worker and organization data from Syspro stays current in Lemlist, so the tools people use daily reflect the org as it actually is.
What you can sync between Lemlist and Syspro
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.
| Lemlist objects | Syspro objects | |
|---|---|---|
| Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Suppliers AP supplier records synced with procurement and payment systems. | |
| Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Inventory items The stock master, kept aligned with WMS and e-commerce catalogs. | |
| Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Sales orders Orders written in from storefronts and CRMs, with status read back out. | |
| Team Members Sender and seat records map outreach activity to reps in other systems. | Purchase orders Procurement documents synced with supplier portals and receiving. | |
| Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting. | |
| Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Bills of materials Product structures referenced when syncing manufacturing data. |

FAQ
Lemlist and Syspro integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Lemlist and Syspro: authenticate both systems, choose the objects to sync (such as Lemlist's Activities and Unsubscribes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Lemlist: Lemlist's data model attaches leads to campaigns, so cross-campaign views of a prospect are assembled by the consuming system rather than provided natively, which makes CRM sync the practical system of record. Syspro: External access goes through e.net business objects that apply the same validation and business logic as the SYSPRO client, so API writes cannot bypass ERP rules. Stacksync's field mapping accounts for these differences between Lemlist and Syspro without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Lemlist and Syspro records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Lemlist and Syspro connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Lemlist–Syspro integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Lemlist and Syspro. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Lemlist: Webhooks on outreach activity events, plus polling. On Syspro: Polling; the ERP does not expose a change feed to external consumers. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
