Upgrade or manage your subscription on the Account page. Using a Pro-only endpoint on the Free plan returns 403 FEATURE_NOT_AVAILABLE.

Checking your plan and usage

GET /v1/account returns your plan, the limits above as numbers and flags (null means unlimited), and each connection your key can send from, with its quota and how much of it is used:

curl https://api.marleyfetch.com/v1/account \
  -H "Authorization: Bearer $MARLEYFETCH_API_KEY"

{
  "success": true,
  "plan": "free",
  "limits": {
    "max_daily_emails": 100,
    "max_templates": 3,
    "templates": true,
    "audiences": false,
    "batch_sending": false,
    "async_sending": false
  },
  "connections": [
    {
      "id": 8,
      "email": "you@example.com",
      "label": "Work",
      "is_default": true,
      "status": "active",
      "quota": { "window": "daily", "limit": 500, "used": 12 }
    }
  ]
}

A key locked to one connection sees only that connection.

Request limits

These apply on every plan.

Limit	Value
Recipients per /send request (to + cc + bcc)	10

Members added per request	10,000

Connection quotas

Separately from your plan, each connection has its own daily or hourly quota that you set to match your provider. It is enforced on every plan.
