What data does OutboundSync write to HubSpot?

Email sends, replies, opens, link clicks, bounces, and lead status updates from Clay. Each event is logged to the contact or lead record's activity timeline, with optional custom properties and company association.

Which HubSpot objects can it update?

OutboundSync can create/update Contacts and Companies (optional). Events are stored as Activities and Timeline Events. No Leads or Deals are touched unless you build a HubSpot workflow.

Do I need admin access to set it up?

Yes, a HubSpot Super Admin authorizes OAuth by installing our HubSpot App. Continued access is required for the app to continue to work.

Can I do this with Zapier, Make, or n8n?

You can use no-code builders for simple Clay automations, but step-based runs are costly and maintenance-heavy as event volume grows. OutboundSync provides a pre-built Clay CRM sync path with searchable historical logs beyond 30 days and usage-based pricing tied to sequencer activity.

When do I need a custom integration instead of no-code automation?

Custom middleware is best when your team wants to own every integration edge case. OutboundSync gives you a faster path with native CRM app capabilities, managed support, and a consistent outbound property model so upstream Clay changes do not force downstream rebuilds.

What breaks first when this scales?

Clay programs at scale need durable event handling to avoid attribution and routing drift. OutboundSync is designed for duplicates, idempotency, queueing, and burst resilience across production outbound workflows.

How is this Clay HubSpot integration priced?

Tiers scale with total outbound messages per month. Full details are on the Pricing page.

Which Clay tier/plan do I need?

OutboundSync is compatible with every Clay plan (Free, Starter, Explorer, Pro, and Enterprise) because it integrates with Clay's Sequences product.

Can I use an existing tool?

Clay has native CRM integrations, but they come with limitations—for example block list syncing is not supported in Clay's Sequencer. OutboundSync fills those gaps with deep activity-based syncing and full control from your CRM.
