Why teams connect Autopilot and Lemlist

Feed Lemlist's records into Autopilot for indexing, classification, and generation, then land the model's output back on those same records, in real time and in both directions.

Autopilot works on data it does not own. The records, conversations, tickets, messages, and events it needs to embed, classify, summarize, or answer questions about actually live in Lemlist, the tool the team uses every day. So the value of Autopilot depends on two flows that most teams stitch together with a custom script or a one-time export: getting Lemlist's data in, and getting the model's results back out to where people can act on them. When either flow runs on a batch or a stale snapshot, the model reasons over yesterday's data and its output never reaches the record it belongs to.

Stacksync syncs Leads, Activities, Unsubscribes, Webhooks from Lemlist into Autopilot continuously, so the model always works from current records instead of a snapshot, and writes Lists, Custom Fields, Smart Segments, Journeys (Triggers), the scores, labels, summaries, drafts, and embedding metadata Autopilot produces, back onto the matching record in Lemlist. The sync is field-level and keyed on a stable identifier, so every output attaches to the exact record it came from and each system keeps its own extra fields untouched.

You decide the direction and the trigger conditions per field: pull records one way to build and keep a retrieval corpus current, push results the other way onto the operational record, or both.

Common use cases

  • 01 Mirror List and Smart Segment membership into a warehouse to power attribution and audience analytics alongside other sources.
  • 02 Stream Activities into a warehouse so opens, clicks, and journey steps sit next to product and revenue data for lifecycle reporting.
  • 03 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • 04 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically

Common sync patterns

Where Autopilot generates text: drafts and summaries where the work happens

Summaries, suggested replies, or generated content from Autopilot sync onto the Lemlist record as a field or note, ready for a person to review before it goes out.

Every output routes back to the right record

Because each item is matched on a stable identifier, an Autopilot result always attaches to the record in Lemlist it was computed from, with no manual reconciliation.

Build a retrieval corpus from Lemlist's records

Records, tickets, messages, or events from Lemlist sync into Autopilot so they can be indexed, embedded, or retrieved as context, without a hand-built extraction job.

What you can sync between Autopilot 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.

Autopilot objects Lemlist objects How this pairing syncs
Activities Per-contact activity and event history (opens, clicks, journey steps); read-only feed used for engagement reporting. 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.
Journeys (Triggers) Automation journeys; a contact can be added to a journey via its trigger endpoint to start automated email or SMS sequences. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Journeys (Triggers) is specific to Autopilot and Unsubscribes to Lemlist — each maps to any object or custom field on the other side.
Contacts Core people records (email, name, custom fields, list and segment membership); upserted two-way as the primary sync object. Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Contacts is specific to Autopilot and Webhooks to Lemlist — each maps to any object or custom field on the other side.
Lists Static contact lists; membership is readable per list and writable by adding or removing contacts. Team Members Sender and seat records map outreach activity to reps in other systems. Lists is specific to Autopilot and Team Members to Lemlist — each maps to any object or custom field on the other side.
Custom Fields User-defined contact properties (string, number, date, boolean); discovered so field keys map cleanly to destination columns. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Custom Fields is specific to Autopilot and Campaigns to Lemlist — each maps to any object or custom field on the other side.
Smart Segments Rule-based dynamic audiences; membership is computed by Autopilot, so it is read-only over the API. Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Smart Segments is specific to Autopilot and Leads to Lemlist — each maps to any object or custom field on the other side.

How changes propagate between Autopilot 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.

Autopilot Lemlist Interval-based propagation

DetectionStacksync polls Autopilot for changes on an incremental schedule, reading only records changed since the previous pass. No CDC.

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

Lemlist Autopilot 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 Autopilot through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Autopilot: The REST API is capped at 100 requests/minute per account; exceeding it returns HTTP 429. Enterprise plans can request a higher limit. Contact writes accept an array for bulk upsert, and list and segment reads paginate via a bookmark cursor.
  • Lemlist: Subject to the platform's API rate limits.

How the Autopilot and Lemlist connectors work

Autopilot

Integration surface
REST API (Autopilot v1); Autopilot rebranded to Ortto in 2021 and the newer Ortto API co-exists with the legacy Autopilot endpoints
Authentication
Per-account API key sent in the autopilotapikey request header (generated in account settings); requests use Content-Type application/json against https://api2.autopilothq.com/v1/
Change detection
No CDC; incremental sync polls the /contacts endpoint with bookmark cursor pagination and updated timestamps. Journey webhook actions can push specific contact events, but there is no general change-subscription webhook, so polling is the reliable path.
