Why teams connect DealCloud and Lemlist
Sync what happens in Lemlist with the customer records in DealCloud, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Lemlist holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist to Task, User, Deal, Company in DealCloud with bi-directional, real-time sync. Activity and record changes in Lemlist update the matching contact or account in DealCloud, and CRM data flows the other way wherever Lemlist can store and use it.
Common use cases
- 01 Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
- 02 Stop or pause sequences automatically when a reply converts to a deal in the CRM
- 03 Mirror DealCloud activities and tasks into an operational database to power internal dashboards without hitting the API on every read.
- 04 Push portfolio and fund performance data from a warehouse into DealCloud so dealmakers see up-to-date metrics on each investment.
Common sync patterns
Where Lemlist runs outreach
Prospects, sends, and replies sync into DealCloud, keeping lead status current without manual imports.
Where Lemlist supplies contact or company data
Enriched fields land directly on records in DealCloud, and refreshes keep them from going stale.
Where Lemlist can store CRM context: fields kept current
Owner, lifecycle stage, or account details from DealCloud sync into Lemlist, so people working there have the context without switching tools.
What you can sync between DealCloud and Lemlist
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.
| DealCloud objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| Activity Synced with incremental and full sync. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |

How changes propagate between DealCloud and Lemlist
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.
DealCloud Lemlist Interval-based propagation
DetectionStacksync polls DealCloud for changes on an incremental schedule, reading only records changed since the previous pass. Incremental via each entry's last-modified timestamp.
DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.
Lemlist DealCloud 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 DealCloud through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- DealCloud: API request limits apply per firm tenant; Stacksync manages throttling and retries automatically.
- Lemlist: Subject to the platform's API rate limits.

FAQ
DealCloud and Lemlist integration FAQ
-

-
Lemlist: Activity events such as replies, opens, bounces, and unsubscribes can be delivered via webhooks, enabling near real-time updates to CRM records without polling every campaign. DealCloud: DealCloud's data model is fully configurable: each firm defines its own entry types (objects) and fields, so syncs map to a firm-specific schema rather than a fixed one. Stacksync's field mapping accounts for these differences between DealCloud and Lemlist 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 DealCloud and Lemlist records are not retained after a sync operation.
