FAQ
Why does email persist despite newer tools?
Because it's the only universal async communication protocol. Slack, WhatsApp, Teams all work within walled gardens. Email works across every organisation, country, and decade. Every 'email killer' for 20 years has failed at this. The winning email products accept persistence and build on top rather than trying to replace.
