Clay HubSpot Integration
Connect Clay's sequencer to HubSpot in minutes—without custom building other Clay tables, Zapier, Make, or n8n.
Learn how to integrate Clay and HubSpot, why most methods fall short, and how OutboundSync gives revenue teams full control.


Integrated campaigns close more deals
Track revenue
Attribute revenue based on your deals. Use lists and reports to understand where outbound is working (or not).
Sync activities
Log your outbound email activity, including sent, replies, opens, clicks, unsubscribes, bounces, and reply categories.
Go omnichannel
Use automation to tap multiple channels, like phones. Use the best tool for each job and grow your pipeline.
Block sending
Use other Clay tables as a suppression or block list, referencing them before starting your campaigns.
Can I use an existing tool?
Clay's native integration is limited in that does not log actual campaign activities to HubSpot. You could build custom HTTP API calls in Clay which would require a custom app and additional work.
On the other hand, OutboundSync can be configured in minutes and supports deep activity-based syncing. Clay is valuable is for mapping properties/fields.
Make, Zapier, and n8n are capable, they take time to build, are difficult to maintain, are costly to scale, and requite custom apps and code for the robust features that OutboundSync provides.
