Best forCreators, 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.
