Best forSMBs and agencies with roughly 500–25,000 contacts that want marketing automation, CRM and email/SMS/WhatsApp messaging in one system and will actually build branching automations rather than simple broadcasts.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 You need frictionless self-service cancellation, predictable refunds, a fully published price at higher contact volumes, guaranteed support SLAs on lower tiers, or only simple newsletter sending. 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.
