使用sendgrid将邮件发送给多个收件人

Question

我想在单个呼叫中使用sendmail向多个收件人发送邮件。我使用的是cakephp 1.3。将邮件发送给单个收件人工作正常。我想知道我是否可以发送邮件给多个收件人(通常是2-5个收件人)。

$this->Email->smtpOptions = array('port'=>'587', 'timeout'=>'30', 'host' => 'smtp.sendgrid.net', 'username'=>'****', 'password'=>'****', 'client' => '***');
$this->Email->delivery = 'smtp';
$this->Email->from = 'Swiso Support <support@swiso.net>';
$this->Email->to = $user['email'];
$this->Email->subject = $title;
$this->Email->template = 'email';
$this->Email->sendAs = 'both';
$this->Email->send();

我是否可以将收件人数组传递给$this->Email->to。

我很感谢你的帮助。

谷歌"cakephp email“显示：

CakePHP 1.3 cookbook: Email

它应该会为您提供所需的内容:例如，有一个允许您向多个收件人发送邮件的bcc字段。

这本书还有一个关于sending multiple messages in a loop.的章节

我不太了解Cakephp，但Sendgrid提供了一种简单的方法，可以在php中向多个收件人发送一封邮件，你可以将这段代码转换为CakePHP。

Sendgrid提供了Mail::addTos 方法，我们可以在其中添加多个我们想要向其发送邮件的邮件。

我们必须将用户电子邮件和用户名的关联数组传递给addTos。

如下例所示：

$tos = [ 
        //user emails       =>  user names  
        "user1@example.com" => "Example User1",
        "user2@example.com" => "Example User2",
        "user3@example.com" => "Example User3"
    ];
    $email->addTos($tos);

如果你想查看sendgrid-php github库中提供的完整示例，那么我将其包含在下面，这样你就可以理解整个示例：

<?php
require 'vendor/autoload.php'; // If you're using Composer (recommended)
// Comment out the above line if not using Composer
// require("<PATH TO>/sendgrid-php.php");
// If not using Composer, uncomment the above line and
// download sendgrid-php.zip from the latest release here,
// replacing <PATH TO> with the path to the sendgrid-php.php file,
// which is included in the download:
// https://github.com/sendgrid/sendgrid-php/releases

$email = new \SendGrid\Mail\Mail(); 
$email->setFrom("test@example.com", "Example User");
$tos = [ 
    "test+test1@example.com" => "Example User1",
    "test+test2@example.com" => "Example User2",
    "test+test3@example.com" => "Example User3"
];
$email->addTos($tos);
$email->setSubject("Sending with Twilio SendGrid is Fun");
$email->addContent("text/plain", "and easy to do anywhere, even with PHP");
$email->addContent(
    "text/html", "<strong>and easy to do anywhere, even with PHP</strong>"
);
$sendgrid = new \SendGrid(getenv('SENDGRID_API_KEY'));
try {
    $response = $sendgrid->send($email);
    print $response->statusCode() . "\n";
    print_r($response->headers());
    print $response->body() . "\n";
} catch (Exception $e) {
    echo 'Caught exception: '.  $e->getMessage(). "\n";
}

简短的回答是:不。我也一直在研究这个问题(使用Sendgrid)，除非你想使用密件抄送字段，否则没有办法在同一个调用中做到这一点。不过，您不必担心只是在循环中发送它们。
