HubSpot has a free plan. The free plan is the right entry point if you're testing the product before committing.
Free Tools
Free
Unlimited users · full CRM · contact + deal management · basic email · branded HubSpot logos · limited marketing-automation depth · contact-tier limits apply
Once you hit the free-tier ceiling — usage caps, branding requirements, or feature gates — you'll need to move to a paid tier. See the full HubSpot pricing.
