Core promise
Reliable delivery and record of communication.
Email ensures messages are sent, received, and stored.
Structural constraint
Private ownership replaces shared truth.
Email is built around individual inboxes. Meaning fragments the moment recipients diverge.
How fragmentation happens
Private truth, not shared reality
Recipients see different slices of the same conversation. Once CC discipline breaks, no common ground exists.
Threaded context collapses
Replies fork meaning. There is no authoritative version of what was decided.
Intent is buried, not bound
Commitments exist only as sentences. They are not attached to owners, timelines, or execution.
Forwarding mutates meaning
Context is stripped while confidence is preserved. Decisions travel without their rationale.
Accountability is implied
Responsibility exists only if someone remembers. Nothing enforces ownership across recipients.
Zero execution visibility
Email cannot see what happened after a decision. Outcomes are disconnected from the original commitment.
Bottom line
Decisions live inside personal inboxes.
Email can record communication. It cannot preserve shared, provable continuity over time.
