New channel: Shared inbox tools
OutboundSync now integrates with HotHawk and MasterInbox to sync inbox data to HubSpot and Salesforce. Beta access is live right now in your account.
OutboundSync now supports:
- Integrating with HotHawk’s shared inbox platform
- Integrating with MasterInbox’s shared inbox platform
- With each, you can sync replies, labels, and more into either HubSpot or Salesforce
- They play nicely with the sequencers you already know and love, like Smartlead, Instantly, EmailBison, and HeyReach
With beta access to Shared Inboxes as a new channel, you can connect your unified inboxes across outbound tools and pipe all reply and lead data directly into your CRM.

This expands OutboundSync’s number of supported channels once again. After starting with email, we’ve added social, phones, and now shared inboxes.

Our job is to get your data deeply synced into your CRM for workflows, reports, AI/agentic tasks, and more.
Get started with Shared Inboxes today by creating a new webhook receiver in the app.
