Two-way sync
Changes in Outreach or Slack instantly reflect in both systems. No stale data, no manual imports.
Keep Outreach and Slack in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Slack 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 Channels, Messages, Threads, Users in Slack to Opportunities, Users, Mailboxes, Prospects in Outreach with bi-directional, real-time sync. Activity and record changes in Slack update the matching contact or account in Outreach, and CRM data flows the other way wherever Slack can store and use it.
Enriched fields land directly on records in Outreach, and refreshes keep them from going stale.
Owner, lifecycle stage, or account details from Outreach sync into Slack, so people working there have the context without switching tools.
Tickets and conversations attach to the right contact and account in Outreach, so sales sees open issues before the next call.
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.
| Outreach objects | Slack objects | |
|---|---|---|
| Accounts Companies grouping prospects, aligned with CRM account ownership | User groups Handles like @support that map to teams in external systems. | |
| Sequences Multi-step cadences; synced as reference data for enrollment automation | Files Uploads attached to messages, retrievable for archiving. | |
| Sequence states Per-prospect enrollments; writing one adds a prospect to a cadence | Reactions Emoji responses that can drive workflows, such as approving a synced record. | |
| Mailings Sent emails with engagement data, pulled for activity analytics | Channels Conversations (public, private, DMs) that messages are read from and posted to. | |
| Calls Logged call records synced into engagement reporting | Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods. | |
| Tasks Rep action items mirrored between Outreach and the CRM | Threads Replies grouped under a parent message timestamp, preserved when archiving conversations. |

Change detection on Outreach: Webhook subscriptions on resource create, update, and destroy events, plus polling. On Slack: Events API webhooks, delivered over HTTP callbacks or Socket Mode. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Slack side: Channels, Messages, Threads, Users, plus custom fields where Slack exposes them. On the Outreach side: Opportunities, Users, Mailboxes, Prospects. 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 Outreach and Slack: Where Slack supplies contact or company data; Where Slack can store CRM context: fields kept current; Where Slack handles support or shared inboxes. Enriched fields land directly on records in Outreach, and refreshes keep them from going stale.
