Why teams connect Lemlist and Zuora
Connect the financial records in Zuora with the work happening in Lemlist, so both stay current without exports or copy-paste.
Zuora holds the financial truth: who the customers are, what they were billed, what they paid. Lemlist is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Payment, Usage, Order and Amendment, Account (Billing Account) in Zuora and Leads, Activities, Unsubscribes, Webhooks in Lemlist in sync, bi-directionally and in real time. Whatever records Lemlist keeps and whatever events it produces, the overlap with Zuora is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- 01 Two-way sync of Accounts and Subscriptions with an operational Postgres database so product and finance teams read billing state in SQL while changes flow back into Zuora.
- 02 Master the Product Catalog (Products and Product Rate Plans) in a database or PIM and write pricing changes into Zuora.
- 03 Mirror campaign performance data into BI tools for outbound reporting across senders
- 04 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
Common sync patterns
Where Lemlist handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Zuora next to the customer they are helping, without logging into the finance system.
Where Lemlist collects payments or triggers charges: events land in Zuora
Payment and charge activity flows into Zuora as it happens, so the books reflect reality without manual reconciliation.
Where Lemlist tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
What you can sync between Lemlist and Zuora
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 | Zuora objects | How this pairing syncs | |
|---|---|---|---|
| Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Subscription Recurring or usage-based subscription tied to an Account; read for revenue state and written when provisioning or changing plans from a CRM or app. | Leads is specific to Lemlist and Subscription to Zuora — each maps to any object or custom field on the other side. | |
| Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Rate Plan and Rate Plan Charge The priced components inside a Subscription; synced so charge amounts, quantities, and effective dates stay aligned with the source system. | Activities is specific to Lemlist and Rate Plan and Rate Plan Charge to Zuora — each maps to any object or custom field on the other side. | |
| Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Product and Product Rate Plan (Product Catalog) The catalog of sellable products and their pricing; usually mastered elsewhere and written into Zuora, or read to map subscription charges. | Unsubscribes is specific to Lemlist and Product and Product Rate Plan (Product Catalog) to Zuora — each maps to any object or custom field on the other side. | |
| Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Invoice Billing documents generated from rate plan charges and order line items; typically read out into an ERP or GL for revenue recognition and reconciliation. | Webhooks is specific to Lemlist and Invoice to Zuora — each maps to any object or custom field on the other side. | |
| Team Members Sender and seat records map outreach activity to reps in other systems. | Payment Payment and refund transactions applied against invoices; read for cash application, dunning, and reconciliation reporting in the warehouse. | Team Members is specific to Lemlist and Payment to Zuora — each maps to any object or custom field on the other side. | |
| Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Usage Metered consumption records; written into Zuora from a metering or warehouse pipeline so consumption-based charges are rated and invoiced. | Campaigns is specific to Lemlist and Usage to Zuora — each maps to any object or custom field on the other side. |
How changes propagate between Lemlist and Zuora
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 Zuora 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 Zuora through its API, with automatic retries and rate-limit backoff.
Zuora Lemlist Sub-second propagation
DetectionZuora notifies Stacksync of record changes through webhook events. Incremental extraction on the indexed UpdatedDate column via ZOQL/AQuA stateful mode (high-water mark), plus Callout Notifications (webhooks) for.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Lemlist: Subject to the platform's API rate limits.
- Zuora: Concurrency limits: 40 concurrent requests by default, 80 for Object Queries, 200 for high-volume operations (doubled for Performance Booster); HTTP 429 on breach with exponential backoff; OAuth token endpoint is not bound by the limit.

FAQ
Lemlist and Zuora integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Lemlist and Zuora: authenticate both systems, choose the objects to sync (such as Lemlist's Leads and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Zuora: The Data Query API is meant for near-real-time operational reads, not bulk; Zuora recommends AQuA stateless mode for full bulk extraction. 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. Stacksync's field mapping accounts for these differences between Lemlist and Zuora 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 Zuora records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Lemlist and Zuora connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Lemlist–Zuora integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Lemlist and Zuora. 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 Zuora: Incremental extraction on the indexed UpdatedDate column via ZOQL/AQuA stateful mode (high-water mark), plus Callout Notifications (webhooks) for event-driven changes. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
