One connection for every inbox behind Master Inbox
Master Inbox brings conversations from many email and social sender accounts into one place. OutboundSync logs its message stream in Salesforce, HubSpot, and more: messages sent and received, label changes, and prospect list changes.
Because Master Inbox is a hub, it is also how several tools reach your CRM. Expandi, Salesflow, PlusVibe, Ashby, and a group of enrichment tools sync through Master Inbox, so one connection covers them all.
Labels are how Master Inbox users mark intent, and they arrive as events your CRM workflows can act on. The sync is one-way, and the OutboundSync team sets up the source with you during onboarding.
What you get
- Messages from connected email and social inboxes as CRM activity
- Label and prospect list changes for routing
