Mailchimp
Email marketing legacy powerhouse — huge SMB user base, but modern developer email APIs are taking new builders.
HIGH THREATReact:
Moat
Mailchimp's moat is massive legacy distribution: acquired by Intuit for $12B, it serves millions of small businesses with all-in-one email deliverability, IP reputation, and CRM sync. Its marketing automation and template builder are well understood by non-technical marketing staff. However, new startups and indie vibe-coders overwhelmingly choose developer-first email platforms like Resend and Loops that offer superior DX and lower pricing.
Challengers

Resend reached over 100,000 developers in its first 18 months with React Email and modern API primitives, capturing the next generation of software products away from Mailchimp.
