Why teams connect Gong and Resend

Sync what happens in Resend with the customer records in Gong, 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 Resend 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 API keys, Emails, Contacts, Audiences in Resend to Interaction Stats (Activity), Trackers & Scorecards, CRM Objects, Library in Gong with bi-directional, real-time sync. Activity and record changes in Resend update the matching contact or account in Gong, and CRM data flows the other way wherever Resend can store and use it.

Common use cases

  • 01 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • 02 Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • 03 Pull call Transcripts by callId into a warehouse or vector store to power search, RAG, and deal-review summaries over what was said on calls.
  • 04 Sync Interaction Stats such as talk ratios and per-rep activity into a coaching database for engagement and rep-performance dashboards.

Common sync patterns

Where Resend runs outreach

Prospects, sends, and replies sync into Gong, keeping lead status current without manual imports.

Where Resend supplies contact or company data

Enriched fields land directly on records in Gong, and refreshes keep them from going stale.

Where Resend can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Gong sync into Resend, so people working there have the context without switching tools.

How changes propagate between Gong 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.

Gong Resend Interval-based propagation

DetectionStacksync polls Gong for changes on an incremental schedule, reading only records changed since the previous pass. Polling POST /v2/calls/extensive on fromDateTime/toDateTime.

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

Resend Gong Sub-second propagation

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

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

Rate-limit considerations

  • Gong: 3 API calls per second and 10,000 calls per day per company by default; exceeding returns HTTP 429 with a Retry-After header, and limits can be raised by contacting Gong.
