Our take
Customer.io is the developer-favorite lifecycle messaging platform. The Liquid templating + behavioral triggers handle complex onboarding/expansion flows nothing else matches. CS Ops teams running multi-step onboarding with 5+ branches need this. For simple newsletter blasts, use HubSpot or Mailchimp. For B2C scale, Iterable. For B2B SaaS lifecycle, Customer.io.
Who it's for: B2B SaaS lifecycle messaging. CS Ops + Growth eng-friendly orgs.
