# Open Question: Will Email Survive as the Agent Identity Protocol?

## Question
Will email survive as the agent identity protocol, or will it be replaced by native Agent-to-Agent (A2A) standards?

## Resolution path
Track the adoption rate of native A2A communication standards (including [[entity-model-context-protocol]] service discovery, OAuth 2.0 Client Credentials, mTLS, and on-chain identity systems) versus continued reliance on programmatic email shims like [[entity-agentmail]] due to their universal acceptance.

## What to watch
- Whether any A2A standard reaches network-effect adoption by 2026.
- Whether enterprises sanction native A2A flows for production agents (vs. tolerating email shims for experiments).
- Counter-signal: AI-augmented email (DKIM, ML verification, ~99% accuracy tools) may keep email viable in **hybrid** human-agent worlds long after pure A2A flows exist.

## Why it matters
The answer determines whether [[claim-email-is-a-shim]] resolves cleanly and whether email-shim startups have a durable business or a temporary one.
