Why teams connect Apollo.io and Salesmate
Run Apollo.io and Salesmate side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs Contacts, Accounts, People (database records), Sequences in Apollo.io with Activities, Pipelines and Stages, Products, Notes in Salesmate in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Common use cases
- 01 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
- 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- 03 Hand off won deals to invoicing or accounting tools automatically.
- 04 Sync Salesmate contacts and deals into a Postgres database or warehouse so SMB teams can report outside the CRM.
Common sync patterns
Migration with a parallel run
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
Divisional or regional split
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Where both track pipeline: deal visibility across systems
Deal stage and value on shared accounts stay visible from either CRM.
What you can sync between Apollo.io and Salesmate
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.
| Apollo.io objects | Salesmate objects | How this pairing syncs | |
|---|---|---|---|
| Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. | Contacts Person records synced with marketing tools and enrichment databases. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. | Users Team member records used for ownership mapping. | Sequences is specific to Apollo.io and Users to Salesmate — each maps to any object or custom field on the other side. | |
| Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. | Companies Organization records linked to contacts and deals. | Deals (Opportunities) is specific to Apollo.io and Companies to Salesmate — each maps to any object or custom field on the other side. | |
| Tasks and calls Rep activity records synced for activity reporting and coaching workflows. | Deals Pipeline opportunities with stage and value, synced out for revenue reporting. | Tasks and calls is specific to Apollo.io and Deals to Salesmate — each maps to any object or custom field on the other side. | |
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Activities Calls, emails, and tasks logged against records and exported for analytics. | Custom fields is specific to Apollo.io and Activities to Salesmate — each maps to any object or custom field on the other side. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Pipelines and Stages Sales process definitions read for stage mapping in syncs. | Accounts is specific to Apollo.io and Pipelines and Stages to Salesmate — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io and Salesmate
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.
Apollo.io Salesmate Interval-based propagation
DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.
DeliveryEach detected change is written to Salesmate through its API, with automatic retries and rate-limit backoff.
Salesmate Apollo.io Sub-second propagation
DetectionSalesmate notifies Stacksync of record changes through webhook events. Webhook triggers via the platform's automation features, with scheduled polling on modified timestamps as fallback.
DeliveryEach detected change is written to Apollo.io through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
- Salesmate: Subject to the platform's API rate limits.

FAQ
Apollo.io and Salesmate integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and Salesmate: authenticate both systems, choose the objects to sync (such as Apollo.io's Contacts and Sequences), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. On Salesmate: Webhook triggers via the platform's automation features, with scheduled polling on modified timestamps as fallback. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Apollo.io side: Contacts, Accounts, People (database records), Sequences, plus custom fields where Apollo.io exposes them. On the Salesmate side: Activities, Pipelines and Stages, Products, Notes. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Apollo.io and Salesmate: Migration with a parallel run; Divisional or regional split; Where both track pipeline: deal visibility across systems. When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
