How can i send bulk mail with PHP in EC2 [closed]

These day, i need to send bulk mail for our company customer. I guess mail amount will be few tens of thousands. I need to send few tens of thousands mail within 24 hours.

My existing system is using PHPMailer with gsmtp on EC2

When i tested to limit amount of send mail with below code, i could send almost 2,000 mail. Because sender mail account is G Suite account. G suite account send limit per 24 hour is 2000.

public function sendMails($mails, $template)
    {
        $mailer = new mailerLib(ACCOUNT, PASSWORD);
        $mailer->setFrom(ACCOUNT, "sender name");


        foreach($mails as $mail) {
            $result = $mailer->addTo($mail['mail'])->sendMail("test", $template);
        }
    }

For sending few tens of thousands mails per a day, i am thinking about Amazon Simple Email Service(SES)

But i dont know there is some problem which i dont know.

Can i send few tens of thousands mails per a day with SES?

Is there any recommend to do it?
