Question

我编写了一个社交应用程序，用户可以在其中注册和登录。

为此，我必须发送电子邮件确认和其他类似的邮件。

我想知道，是否编写了手动代码（通过cronjob每小时运行一次）是否足够，还是应该使用mailchimp或其他大量电子邮件发送网站？我不想让我的电子邮件成为垃圾邮件。目前不是，但恐怕将来可能会改变。

我写了以下内容：

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Select maximum 50 unsent mails
$qry = $db->prepare('SELECT q.*, u.*, c.* FROM emailQueuer AS q INNER JOIN userData AS u ON u.id = q.userId INNER JOIN emailConfirmations AS c ON c.userId = q.userId WHERE q.sendingStatus = 0 AND q.sentStatus = 0 AND q.retryAttempts < 5 LIMIT 0, 50');
$qry->execute();
if ($qry->rowCount() > 0) {
    $mails = $qry->fetchAll();

    for( $i = 0 ; $i < count($mails) ; $i++ ){


        // BASIC DATA
        $email = $mails[$i]["email"];
        $userId = $mails[$i]["userId"];
        // ...ETC


        $subject = "Test";

        $contentJSON = $mails[$i]["content"];
        $content = json_decode($contentJSON, true);
        $patterns = $content["patterns"];
        $patterns []= "/{email-address}/";
        $patterns []= "/{user-id}/";


        ob_start();
        include(ROOT_DIR . '/resources/email-sheets/testsheet.html');
        $output = ob_get_contents();
        ob_end_clean();
        $mailHTML = preg_replace($patterns, $replacements, $output);
        $mailPLAIN = $subject;   



        $qry = $db->prepare('UPDATE emailQueuer SET sendingStatus = 1, retryAttempts = (retryAttempts + 1) WHERE id = :id');
        $qry->bindParam(':id', $mails[$i]["id"], PDO::PARAM_INT);
        $qry->execute();

        $mail = new PHPMailer();
        $mail->isSMTP();
        $mail->SMTPDebug = 0;
        $mail->Host = 'mail.privateemail.com';
        $mail->Port = 587;
        $mail->SMTPAuth = true;
        $mail->Username = 'noreply@mysocialappsite.com';
        $mail->Password = 'XXXXXX';
        $mail->setFrom('noreply@mysocialappsite.com', 'mysocialappsite');
        $mail->addReplyTo('contact@mysocialappsite.com', 'Contact');
        $mail->addAddress($email, ($firstName . ' ' . $lastName));
        $mail->Subject = $subject;
        $mail->msgHTML($mailHTML, __DIR__);
        $mail->AltBody = $mailPLAIN;
        $mail->CharSet = 'UTF-8';


        try {
            $mail->send();

            // Success
            $qry = $db->prepare('UPDATE emailQueuer SET sendingStatus = 0, sentStatus = 1, time = :time WHERE id = :id');
            $qry->bindParam(':id', $mails[$i]["id"], PDO::PARAM_INT);
            $qry->bindParam(':time', Time(), PDO::PARAM_INT);
            $qry->execute();
        } catch (Exception $e) {

            // Error
            echo 'Mailer Error: ' . $mail->ErrorInfo;

            $qry = $db->prepare('UPDATE emailQueuer SET sendingStatus = 0, time = :time WHERE id = :id');
            $qry->bindParam(':id', $mails[$i]["id"], PDO::PARAM_INT);
            $qry->bindParam(':time', Time(), PDO::PARAM_INT);
            $qry->execute();

            //Reset the connection to abort sending this message
            //The loop will continue trying to send to the rest of the list
            $mail->smtp->reset();
        }
        //Clear all addresses and attachments for the next iteration
        $mail->clearAddresses();
        $mail->clearAttachments();
    }


}

我使用SSL连接，电子邮件提供商是namecheap.com （站点提供商为DigitalOcean）

您对此有何看法？

普通的PHP大量电子邮件发送VS mailchimp？
