Recipient

Defining the recipient is as simple as declaring the recipient variable that must be a valid email address.

{
  // Other variables
  "recipient": "foo@example.org"
}

Multiple recipients

If you need to send the same email to multiple recipients you can do it as well by using the recipients key instead of recipient:

{
  // Other variables
  "recipients": [
    "foo@example.org",
    "bar@example.org"
  ]
}

You can even define specific variables, cc, bcc and more for each single recipient.
Per-recipient data will be merged with global data, take an example to this snippet:

{
  // Other variables
  "recipients": [
    {
      "email": "foo@example.org",
      "variables": {
        "name": "Foo"
      }
    },
    {
      "email": "foo@example.org",
      "cc": "bar2@example.org"
    }
  ],
  "variables": {
    "companyName": "MailCarrier",
    "name": "Default"
  },
  "cc": "global+cc@example.org",
}

What will happen here:

1. The first email will be sent to foo@example.org with name: Foo and cc: global+cc@example.org;
2. The second email will be sent to bar@example.org with name: Default and cc: bar2@example.org.

Both emails will have access to the companyName: MailCarrier variable. The same applies to attachments and remote attachments.
