使用mailchimp发送交易邮件

Question

我正在使用laravel开发Web应用程序。在此应用程序中，我必须向用户发送电子邮件。现在，我想使用mailchimp发送那些电子邮件。谁能指导我如何使用laravel中的mailchimp发送一对一的电子邮件。我正在使用以下代码发送电子邮件，请检查并告知我该怎么做

$apikey = '<key>-us12';
    $to_emails = array('test@gmail.com');
    $to_names = array('test');
    $message = array(
        'html' => 'Yo, this is the <b>html</b> portion',
        'text' => 'Yo, this is the *text* portion',
        'subject' => 'This is the subject',
        'from_name' => 'OMO CRM',
        'from_email' => 'customerservice@test.com',
        'to_email' => $to_emails,
        'to_name' => $to_names
    );
    $tags = array('WelcomeEmail');
    $params = array(
        'apikey' => $apikey,
        'message' => $message,
        'track_opens' => true,
        'track_clicks' => false,
        'tags' => $tags
    );
    $url = "https://us12.api.mailchimp.com/3.0/";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url . '?' . http_build_query($params));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $result = curl_exec($ch);
    echo $result;
    curl_close($ch);
    $data = json_decode($result);
    echo "Status = " . $data->status . "\n";

我无法使用上述代码发送电子邮件。
