| Pricing | Comfort from $12/month · free tier: Free $0: up to 250 subscribers, 2 seats, 2,500 monthly emails, 3 active automations (max 5 steps), 1 website, 1 landing page, 3 forms, all 3 email editors, community support only | Essentials from $100/month, billed monthly (5,000 profiles, 1M emails/month) · free tier: No free-forever plan; companies that have raised under $10M can get a full year free via the startup program.

| Pricing model | Subscription (tiered by active subscriber count) with Freemium tier | Subscription with usage-based overages |
| Best for | Creators, authors, solopreneurs and small teams under roughly 5,000 subscribers with clean opt-in lists who want newsletters, automations, a site or landing page and commission-free product/booking sales on one affordable bill. | Funded SaaS or mobile product companies with 5k–100k profiles and engineering resource to send event data, who need email coordinated with push, in-app and SMS in one journey — especially startups eligible for the under-$10M free year. |
| Avoid if | Your list was bought, scraped or inherited, you cannot survive a sudden sending suspension, you want to prepay annually before a proven send, you need marketing plus transactional email in one contract, or you need deep automation logic beyond 100 steps. | You want cheap newsletters, forms or landing pages, have no developer support for setup, sit on a large dormant B2C list you will still be billed for, need month-to-month flexibility above $100/month, or require phone-based billing escalation. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
