Question

我有一个超过12,000个用户的数据库，我正在尝试向所有用户发送电子邮件，每个用户根据他们在数据库中的信息提供特定信息。我已经发了这封电子邮件，当一个cron在星期日早上6点运行并且我在上周五完成了这个功能并且它在星期天运行，即昨天。发生了什么。

1。）电子邮件保持从早上6点到晚上7点全天发送

2.）到那时，它只发送给了750个用户

3.）之后由于我不知道的原因它完全停止了

PS： I am sending the emails using PHPMailer，使用模板，我使用循环遍历所有用户并为每个用户执行计算，使用信息填写模板，然后发送电子邮件。

下面是一个代码片段，展示了我的所作所为......

foreach($users as $user){
            // Construct the email template
            $htmlContent = file_get_contents(__DIR__ . '/../../templates/weekly_spending_template.html');

            // Replace some place holders with user's custom information.
            $htmlContent = preg_replace('/\$bars/', $bars, $htmlContent);
            $htmlContent = preg_replace('/\$labels/', $labels, $htmlContent);
            $htmlContent = preg_replace('/\$total/', $currency . ' ' . number_format($total, 0), $htmlContent);
            $htmlContent = preg_replace('/\$budget/', $currency . ' ' . number_format($budget, 0), $htmlContent);
            $htmlContent = preg_replace('/\$first_name/', ucfirst($user->first_name), $htmlContent);
            $htmlContent = preg_replace('/\$remark/', $remark, $htmlContent);
            $htmlContent = preg_replace('/\$percentage_difference/', $percentage_difference, $htmlContent);
            $htmlContent = preg_replace('/\$others/', $others, $htmlContent);


            try {
                // Setup email parameters
                $mail = new PHPMailer(true);
                $subject = "Your weekly spending breakdown";


                $mail->IsSMTP();
                $mail->SMTPDebug = 0;
                $mail->SMTPAuth = true;
                $mail->SMTPSecure = "ssl";
                $mail->Host = "smtp.gmail.com";
                $mail->Port = 465;
                $mail->AddAddress($user->email, ucfirst($user->first_name) . ' ' . ucfirst($user->last_name));
                $mail->Username = "mymail@example.com";
                $mail->Password = "myPassW0rd";
                $mail->SetFrom('mymail@example.com', 'Name');
                $mail->AddReplyTo("mymail@example.com", "Name");
                $mail->Subject = $subject;
                $mail->Body = $htmlContent;
                $mail->isHTML(true);

                if (!$mail->send()) {
                    echo "Message was not sent.\n";
                    echo 'Mailer error: ' . $mail->ErrorInfo . "\n";
                } else {
                    echo "Message has been sent.\n";
                }
            } catch (\Exception $ex) {
                echo $ex->getMessage();
            }
}

拜托，有人可以向我提出如何使这一过程更有效，更快或更好的选择来实现这一目标的建议吗？感谢。

Answer 1

您可以考虑使用swiftmailer（链接下方），因为它大部分都是您想要的并且在许多产品和框架中使用，因此您可以确定它相当稳定。

每天只能发送500封邮件@每小时20封邮件

请参阅：https://swiftmailer.symfony.com/docs/sending.html#sending-emails-in-batch
