Most email startups target non-problems because core email protocols work reliably and universally.
Building real email infrastructure involves complex SMTP delivery, spam filtering, storage, authentication, and deliverability challenges.
Email’s massive network effects and standardized protocols make it nearly impossible for new clients to displace established providers like Gmail or Outlook.
Over 80% of email startups either shut down, pivot away, or get acquired and discontinued shortly after.
Successful companies focus on infrastructure and developer tools rather than end-user email apps, enhancing existing workflows instead of replacing them.
AI-powered features and new interfaces rarely provide enough value to overcome technical debt and switching costs.
The few lasting successes, like SendGrid and Xobni, build on top of proven protocols and solve real workflow problems.
Long-term, profitable email ventures emphasize reliability, protocol compatibility, and serving developers over flashy features.
