How can I use the API to send an email to a user who is not yet registered in my Pushwoosh database?

Yes, you can send emails to new users who are not yet in your database by using the auto-registration feature in the /createEmailMessage API call.

When making your API request, include the "use_auto_registration": true parameter within the notifications object. This will automatically register the email address provided in the devices array as a new user profile before sending the email.

Here is an example of a payload with this parameter included:

{
  "request": {
    "application": "YOUR_PUSHWOOSH_APP_ID",
    "auth": "YOUR_PUSHWOOSH_API_KEY",
    "notifications": [
      {
        "send_date": "now",
        "preset": "YOUR_PRESET_CODE",
        "devices": [
          "new_user@example.com"
        ],
        "use_auto_registration": true
      }
    ]
  }
}

By adding "use_auto_registration": true, you ensure that emails are delivered to new recipients without needing to register them in a separate step.

Alternatively, you can add new email subscribers to your database using other methods, such as: * Importing a list from a CSV file. * Using the /registerEmail or /registerEmailUser API methods when a user signs up on your website or app.
