Instantly HubSpot Integration
Connect Instantly’s multi‑domain cold‑email power to HubSpot in minutes—without custom building and maintaining it in Clay, Zapier, Make, or n8n.
Learn how to integrate Instantly 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 OutboundSync as your block list. Source from your CRM and prevent outreach to key contacts and companies.
Can I use an existing tool?
Instantly's native integration is designed only to pull from HubSpot and push to Instantly for campaigns. It's not bidirectional. So it simply does not solve the problem of pushing data into HubSpot.
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.
Clay is powerful for enrichment but its cell size limits, table row limits, and silent webhook failures lead to data loss for this use case.
