/v1 is now generally available — shipped in v1.5.0.

Hosted (e2a.dev) · Quickstart · Examples · Concepts · API · SDKs · MCP · Deploy · FAQ

[!IMPORTANT] The core /v1 API and SDKs are stable and generally available (GA) as of v1.5.0: no breaking changes within /v1. That tag is the compatibility baseline — every later release is audited against it. A small, explicitly enumerated surface is still beta and may change before it is declared stable — contacts & outreach, scheduled sending (send_at), email templates & starter templates, the reviews (HITL) queue, agent protection config, agent-scoped suppressions, managed unsubscribe, message lifecycle diagnostics, and the thread_id message-read field. Beta surface is marked x-stability-level: beta in the OpenAPI spec and (beta) in the docs; where only specific values of a stable field are beta (the scheduled send status, the screening/review-hold event types, the blocked_by_policy error code), the field carries x-experimental-values naming exactly those values. Everything else is covered by the GA freeze. See the full matrix in docs/api.md → Stability: GA and beta surface. Existing v1.0.x application/cherry-pick tags predate the API freeze and are not /v1 compatibility baselines.

e2a is an authenticated email gateway for AI agents. It receives inbound mail, evaluates SPF, every DKIM signature, and DMARC, and delivers structured authentication evidence over whichever channel fits your runtime. Outbound goes back out through an HTTP API, with an optional human-in-the-loop approval gate.

Four ways to plug an agent in:
