## Request

- Base URL: `https://api.emelia.io`
- URL: `https://api.emelia.io/email-providers/warmup`
- Auth: API key in header `Authorization`

Warmup state of every mailbox (a warmup record is created on the fly for mailboxes that have none). No pagination: a `page` parameter is ignored. The `_id` of an item is the warmup id.

## Response `200`

Success.

- object
  - `success` unknown
  - `warmups` object[]
    - `email` string
    - `_id` string: MongoDB ObjectId: 24 hexadecimal characters.
    - `provider` string: MongoDB ObjectId: 24 hexadecimal characters.
    - `running` boolean
    - `disabledReason` string
    - `stats` object
    - `health` object, nullable: Last DNS and deliverability diagnosis, or null.

## Other responses

- `400`: Invalid request or business error (the API also uses 400 for "not found").
- `401`: Missing, malformed, unknown or disabled API key. The key must be exactly 48 characters, otherwise it is treated as a session token and rejected the same way.
- `500`: Unexpected error. IMPORTANT: this is also what you receive today when the per minute quota of your account is exceeded (the quota error is not mapped to 429 for API keys). No `Retry-After` header is sent. Wait until the next minute window before retrying.
