Compare MailerLite and HubSpot for your team
HubSpot and MailerLite serve different budgets and use cases. HubSpot's Free tier supports up to 2 users, and paid tiers (Starter at $20/mo, Professional at $890/mo with a $3,000 onboarding fee, Enterprise at $3,600/mo with a $7,000 onboarding fee) add CRM-integrated lead scoring, omni-channel automation with unlimited actions, and an AI Content Agent. This fits organizations that need marketing tied directly to sales/CRM data and can absorb higher subscription and onboarding costs. MailerLite's Free plan covers up to 250 subscribers with automation, A/B testing, and a drag-and-drop editor included, and its Comfort ($12/mo) and Power ($25/mo) plans add unlimited automations, unlimited emails, and an AI writing assistant at a much lower price point. This suits small businesses or solo marketers who want core email marketing and automation without CRM complexity or large upfront fees. Transactional email and deliverability tooling are more built-in on HubSpot; MailerLite routes transactional email to a separate product (MailerSend) and reserves deliverability support for its custom Enterprise plan.
