Note
HubSpot Marketing Hub (the automation platform — email automation, workflows, landing pages, A/B testing, lead scoring) has no forever-free tier — a 14-day trial then Starter from ~$20/mo (billed annually) for 1,000 marketing contacts. The free HubSpot CRM does include free marketing tools (forms, ad management, email tracking, live chat) but not the email-marketing automation workflows. The all-in-one inbound-marketing default for B2B.
