# Email Health

`GET /api/v1/admin/email-health`

## Request

- Base URL: `https://api.peil.app` (the document declares no server; this is the origin it was published from)
- URL: `https://api.peil.app/api/v1/admin/email-health`
- Auth: OAuth 2 (password, token URL `/api/v1/auth/jwt/login`)

Deliverability of the shared sending domain.

Every user's mail leaves as noreply@mail.peil.app, so reputation is a single
shared asset: one account's complaints degrade delivery for everyone. Per-user
email history cannot show that — the damage is only visible in aggregate,
which is why this is an operator view and not a user-facing one.

Deliberately built on the *negative* signals only. Opens and clicks are not
deliverability metrics and are actively misleading here: corporate mail
gateways fetch every link on delivery, so a single scanned message can log
several clicks and an open with no human involved (observed July 2026 —
four clicks in the delivery minute, before the first open). Bounces and
complaints have no such automated analogue.
