Why teams connect Datadog and Lemlist

Connect the tickets, records, and events in Lemlist to the systems engineering runs in Datadog, kept current in real time and in both directions.

Lemlist is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Datadog is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Campaigns, Leads, Activities, Unsubscribes in Lemlist with Metrics, Incidents, Service Level Objectives, Hosts in Datadog field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

Common use cases

  • 01 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • 02 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 03 Sync Monitors and their alert state into Postgres so reliability teams query alert history and noisy-monitor trends in SQL.
  • 04 Provision and update Datadog Monitors from a config database or Git so alert definitions stay consistent across teams and environments.

Common sync patterns

Where Datadog tracks engineering work: requests become issues

A ticket or request raised in Lemlist opens or updates a matching issue in Datadog, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.

Where Datadog moves messages between services: activity lands on the stream

Records created or changed in Lemlist publish to the queue or topic in Datadog as they happen, so downstream services react to real events rather than polling for them.

Where Datadog is the directory or identity source: one set of users

People and accounts in Lemlist stay matched to the users in Datadog, so access, provisioning, and org changes propagate instead of being keyed in twice.

What you can sync between Datadog 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.

Datadog objects Lemlist objects How this pairing syncs
Logs Log events searched via the v2 Logs search endpoint by time window and submittable through the log intake API; commonly streamed to a warehouse for retention beyond Datadog's storage period. Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Logs is specific to Datadog and Webhooks to Lemlist — each maps to any object or custom field on the other side.
Events The event stream (deploys, alerts, comments) searched via the v2 Events endpoint and posted via POST /api/v1/events; used to correlate deploy and incident timelines or to publish deploy and pipeline events into Datadog. Team Members Sender and seat records map outreach activity to reps in other systems. Events is specific to Datadog and Team Members to Lemlist — each maps to any object or custom field on the other side.
Dashboards Dashboard definitions and widgets via the v1 Dashboards API with full CRUD; exported for backup and audit, or created and updated programmatically from a source of truth. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Dashboards is specific to Datadog and Campaigns to Lemlist — each maps to any object or custom field on the other side.
Metrics Time-series metrics queried in aggregate windows through the query API and submitted via POST /api/v1/series; individual raw points cannot be extracted beyond retention. Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Metrics is specific to Datadog and Leads to Lemlist — each maps to any object or custom field on the other side.
Incidents Incident records from the v2 Incidents API with full CRUD, including status and timeline fields; landed in a database for MTTR reporting or created and updated from an external incident workflow. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Incidents is specific to Datadog and Activities to Lemlist — each maps to any object or custom field on the other side.
Service Level Objectives SLO definitions and status history via the v1 SLO API with full CRUD; read out for reliability and error-budget reporting, or provisioned and updated from a reliability config. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Service Level Objectives is specific to Datadog and Unsubscribes to Lemlist — each maps to any object or custom field on the other side.

How changes propagate between Datadog 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.

Datadog Lemlist Sub-second propagation

DetectionDatadog notifies Stacksync of record changes through webhook events. Polling with time-windowed search queries on Logs and Events (timestamp cursor).

DeliveryEach detected change is written to Lemlist through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Datadog: Per-endpoint limits return HTTP 429 with X-RateLimit-Limit/-Remaining/-Period/-Reset headers. Log ingestion and metric submission are not rate limited; search endpoints such as Logs and Events queries carry quotas that Datadog Support can raise.
  • Lemlist: Subject to the platform's API rate limits.

How the Datadog and Lemlist connectors work

Datadog

Integration surface
REST API (v1 and v2)
Authentication
API key (DD-API-KEY) plus an Application key (DD-APPLICATION-KEY) sent as request headers; application keys are tied to the creating user and inherit that user's permissions and authorization scopes.
Change detection
Polling with time-windowed search queries on Logs and Events (timestamp cursor); monitor alerts can also push via the Webhooks notification integration. No modified-date CDC on mutable objects.
