# Check Email Content

Validates a stored drag-and-drop email body for empty text, incomplete blocks, missing footer placeholders and known text/link contrast issues (WCAG 4.5:1). Findings identify blocks and fixes. Does not check signatures, rendered CSS, spam, live links or sending readiness; publication may still warn or fail. Previous-editor emails are refused. Reads only.

## Input schema:

```json
{
  "type": "object",
  "properties": {
    "emailId": {
      "type": [
        "null",
        "integer"
      ],
      "description": "ID of the email; omit when the editor URL is given",
      "default": null,
      "minimum": 1
    },
    "editorUrl": {
      "type": [
        "null",
        "string"
      ],
      "description": "Editor URL of the email, as a previous read returned it; omit when the email ID is given",
      "default": null,
      "minLength": 12,
      "maxLength": 500
    },
    "accountId": {
      "type": [
        "null",
        "integer"
      ],
      "description": "User ID of the account; omit for the account the access token works in",
      "default": null,
      "minimum": 1
    }
  },
  "additionalProperties": false
