About OutboundSync integrations

OutboundSync connects the outbound stack — sales engagement platforms like Smartlead, Instantly, HeyReach, and Reply.io, enrichment and orchestration tools like Clay, and AI agents — to HubSpot, Salesforce, Close, and Attio. Sync sends, opens, replies, and meetings as native CRM activity; route inbound replies and bookings; attribute revenue to outbound channels; and keep block lists and unsubscribes in step across every tool.
