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
