Why teams connect Autopilot and Resend

Feed Resend'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 Resend, 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 Resend'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 Audiences, Broadcasts, Domains, Email events from Resend into Autopilot continuously, so the model always works from current records instead of a snapshot, and writes Custom Fields, Smart Segments, Journeys (Triggers), Activities, the scores, labels, summaries, drafts, and embedding metadata Autopilot produces, back onto the matching record in Resend. 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 CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • 04 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.

Common sync patterns

Keep the model's knowledge current

As records change in Resend, the synced copy in Autopilot updates within seconds, so retrieval and generation reason over live data rather than a stale export.

Where Autopilot classifies or scores: results land on the record

Categories, sentiment, priority, or scores produced by Autopilot write back onto the matching record in Resend, so the team acts on them in the tool they already use.

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

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

What you can sync between Autopilot and Resend

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 Resend objects How this pairing syncs
Contacts Core people records (email, name, custom fields, list and segment membership); upserted two-way as the primary sync object. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Lists Static contact lists; membership is readable per list and writable by adding or removing contacts. Domains Verified sending domains with DNS and DKIM status. Lists is specific to Autopilot and Domains to Resend — 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. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Custom Fields is specific to Autopilot and Email events to Resend — 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. API keys Scoped credentials managed per environment for send and read access. Smart Segments is specific to Autopilot and API keys to Resend — each maps to any object or custom field on the other side.
Journeys (Triggers) Automation journeys; a contact can be added to a journey via its trigger endpoint to start automated email or SMS sequences. Emails Sent messages retrievable by ID with current delivery status. Journeys (Triggers) is specific to Autopilot and Emails to Resend — each maps to any object or custom field on the other side.
Activities Per-contact activity and event history (opens, clicks, journey steps); read-only feed used for engagement reporting. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Activities is specific to Autopilot and Audiences to Resend — each maps to any object or custom field on the other side.

How changes propagate between Autopilot and Resend

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

Resend Autopilot Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.

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.

How the Autopilot and Resend 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.
