Email startups have an 80%+ failure rate because they try to solve problems that don't exist. Most build UI layers on top of existing infrastructure rather than actual email servers. Companies like Skiff, Sparrow, and Mailbox were acquired and shut down, while successful email businesses focus on infrastructure (SendGrid, Mailgun) or enhance existing workflows rather than replacing them. The core email protocols (SMTP, IMAP, POP3) work perfectly and have massive network effects that make replacement nearly impossible.
