What are 'marketing contacts' and why am I billed for them?

Marketing contacts are those you actively market to via email. You're billed based on the number of contacts in this list, separate from your total stored contacts. You can have unlimited non-marketing contacts for free.

Why is there a mandatory onboarding fee for Professional and Enterprise?

The one-time onboarding fee ($3,000-$7,000) covers mandatory training and platform setup by HubSpot experts. This ensures proper configuration for complex features like automation and custom reporting, reducing implementation failure risk.

Can I integrate HubSpot with my custom-built application?

Yes. HubSpot provides a comprehensive REST API and developer tools for building custom integrations. You can use OAuth 2.0 for authentication and manage data across contacts, companies, deals, and custom objects programmatically.
