Why teams connect Freshsales and Iterable

Keep the people you sell to and the people you market to in one shared view: Freshsales and Iterable sync contacts, accounts, and engagement in real time, in both directions.

Freshsales owns the customer relationship and the pipeline; Iterable runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Deals, Tasks, Appointments, Notes in Freshsales with Events, Campaigns, Templates, Lists in Iterable field by field, in real time, and in both directions. You decide which system owns which fields — Freshsales can own account and opportunity status while Iterable owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync sales activities and appointments into analytics tools for rep productivity reporting.
  • 02 Two-way sync of contacts and accounts between Freshsales and a Postgres database so product and data teams query CRM data with SQL.
  • 03 Track product and revenue Events (custom events, trackPurchase, updateCart) into Iterable from an app or database so journeys trigger on live behavior.
  • 04 Export Iterable engagement data (emailSend, emailOpen, emailClick, emailBounce, purchase) into a warehouse for deliverability and campaign reporting.

Common sync patterns

Segments and audiences follow the CRM

Where Iterable builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Freshsales, so who receives a campaign reflects current pipeline reality instead of a stale export.

Where Iterable generates leads: hand-off without re-keying

New leads or responders captured in Iterable flow into Freshsales assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

What you can sync between Freshsales and Iterable

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.

Freshsales objects Iterable objects How this pairing syncs
Appointments Scheduled meetings readable for activity analytics. Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. Appointments is specific to Freshsales and Commerce / Purchases to Iterable — each maps to any object or custom field on the other side.
Notes Free-text records attached to contacts, accounts, and deals. Export data Historical user and event records pulled through the Export API (/api/export/data.json, data.csv, and userEvents) across data types like emailSend, emailOpen, emailClick, emailBounce, purchase, and customEvent. Notes is specific to Freshsales and Export data to Iterable — each maps to any object or custom field on the other side.
Sales activities Configurable activity types logged against records, useful for engagement scoring. Users User profiles keyed by email or userId with custom data fields; upserted via POST /api/users/update, read via GET /api/users/{email} or getByUserId, bulk-written via /api/users/bulkUpdate (up to 1000 users per call), and deleted or GDPR-forgotten. Sales activities is specific to Freshsales and Users to Iterable — each maps to any object or custom field on the other side.
Products Catalog items attached to deals for line-level revenue data. Events Custom and system events tracked via /api/events/track and /api/events/trackBulk (up to 1000 events per call); a single user's event history is read via GET /api/events/{email}. Products is specific to Freshsales and Events to Iterable — each maps to any object or custom field on the other side.
Contacts Person records carrying lifecycle stages; the main entity for two-way CRM syncs. Campaigns Email, SMS, push, and in-app sends; metadata and metrics read via GET /api/campaigns and /api/campaigns/metrics, created and sent via /api/campaigns/create and /api/campaigns/trigger. Contacts is specific to Freshsales and Campaigns to Iterable — each maps to any object or custom field on the other side.
Accounts Company records kept aligned with billing, ERP, and warehouse tables. Templates Reusable email/SMS/push/in-app message templates with handlebars fields; read via /api/templates and per-channel get endpoints, written via /api/templates/email/upsert and the other channel upserts. Accounts is specific to Freshsales and Templates to Iterable — each maps to any object or custom field on the other side.

How changes propagate between Freshsales and Iterable

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.

Freshsales Iterable Sub-second propagation

DetectionFreshsales notifies Stacksync of record changes through webhook events. Polling with updated-at filters through views.

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

Iterable Freshsales Sub-second propagation

DetectionIterable notifies Stacksync of record changes through webhook events. System Webhooks push email/SMS/push/in-app and custom events (send, open, click, bounce, complaint, unsubscribe) as JSON POSTs in near real time.

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

Rate-limit considerations

  • Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.
  • Iterable: Limits are per endpoint and per project/key; exceeding one returns HTTP 429, so exponential backoff is advised. Event tracking allows far higher volume than metadata endpoints like campaigns/templates, and the Export API is throttled more tightly. Since Nov 10, 2025, passing the key in the query string or body is rate-limited more strictly than the Api-Key header.
