Our verdict
These tools serve different email needs. Mailchimp is the safe all-rounder for marketing teams who want templates, automation, and analytics in one dashboard. Kit (formerly ConvertKit) is built for creators and content-driven businesses — its subscriber-first model and clean editor focus on what matters for newsletters. Resend is the modern developer tool for transactional email — beautiful API, React Email components, and no subscriber-count pricing. Most startups need two of these: Resend for transactional email plus Mailchimp or Kit for marketing.
