PHP向Amazon SES发送大量电子邮件

Question

我有一个在线软件,可以向Amazon SES发送电子邮件.目前我有一个cron作业,通过SMTP发送电子邮件与phpmailer发送消息.目前我必须将发送限制最大限制为每分钟300左右,以确保我的服务器没有超时.我们看到增长,最终我想发送到10,000或更多.

有没有更好的方式发送到亚马逊SES,或者这是其他人做的,但只有更多的服务器运行工作负载？

提前致谢!

您可以尝试使用AWS SDK for PHP.您可以通过SES API发送电子邮件,SDK允许您并行发送多封电子邮件.这是一个代码示例(未经测试且仅部分完成)以帮助您入门.

<?php

require 'vendor/autoload.php';

use Aws\Ses\SesClient;
use Guzzle\Service\Exception\CommandTransferException;

$ses = SesClient::factory(/* ...credentials... */);

$emails = array();
// @TODO SOME SORT OF LOGIC THAT POPULATES THE ABOVE ARRAY

$emailBatch = new SplQueue();
$emailBatch->setIteratorMode(SplQueue::IT_MODE_DELETE);

while ($emails) {
    // Generate SendEmail commands to batch
    foreach ($emails as $email) {
        $emailCommand = $ses->getCommand('SendEmail', array(
            // GENERATE COMMAND PARAMS FROM THE $email DATA
        ));
        $emailBatch->enqueue($emailCommand);
    }

    try {
        // Send the batch
        $successfulCommands = $ses->execute(iterator_to_array($emailBatch));
    } catch (CommandTransferException $e) {
        $successfulCommands = $e->getSuccessfulCommands();
        // Requeue failed commands
        foreach ($e->getFailedCommands() as $failedCommand) {
            $emailBatch->enqueue($failedCommand);
        }
    }

    foreach ($successfulCommands as $command) {
        echo 'Sent message: ' . $command->getResult()->get('MessageId') . "\n";
    }
}

您还可以考虑使用Guzzle BatchBuilder和朋友来使其更加强大.

您需要对此代码进行微调,但您可能会获得更高的电子邮件吞吐量.
