NodeMailer，发送特定数量的电子邮件

我需要帮助使用 nodemailer 发送特定数量的电子邮件，假设我想向特定的人发送 20 封电子邮件。 这是我的代码。

const transporter = nodemailer.createTransport(smtpTransport({
  host: "smpt.gmail.com", //smtp server
  port: 587,
    pool: true,
  secure: false, // true for 465, false for other ports
  auth: {
    user: "[email protected] /cdn-cgi/l/email-protection", // mail
    pass: "testtesttest" // password
  }
}));
transporter.close();


// setup email data with unicode symbols
let mailOptions = {
  from: '"Test Test" <[email protected] /cdn-cgi/l/email-protection>', // sender address
  to: mailto, // list of receivers
  subject: args[1], // Subject line
  text: args[2] // 
};

async function sendMail() {
  let info = await transporter.sendMail(mailOptions);
  sending = true;
}

const SendingMessage = setInterval(() => {
  var mailto = args[0];
  mailOptions.subject = args[1];
  var mailtxt = args[2];

  sendMail();
}, 1500);

我如何让它发送“嘿”这样的消息给[电子邮件受保护] /cdn-cgi/l/email-protection仅5次。因为目前它只会发送“嘿”，直到我达到我的 smtp 发送限制

首先创建一个要发送的邮件内容数组，例如；

const mails2send = [
{
 from: '..',
 to: '..',
 subject: '..'
 text: '..'
},
{
 from: '..',
 to: '..',
 subject: '..'
 text: '..'
},
{
 from: '..',
 to: '..',
 subject: '..'
 text: '..'
}
]

修改 sendMail 函数以接受参数。

async function sendMail(mailOptions) {
  let info = await transporter.sendMail(mailOptions);
  sending = true;
  return sending;
}

然后通过映射mails2send

mails2send.forEach( item => sendMail(item ))

Update看来您可能正在谈论您的 setInterval 函数

let counter = 0;

const SendingMessage = setInterval(() => {
  
  var mailto = args[0];
  mailOptions.subject = args[1];
  var mailtxt = args[2];
  sendMail();

  if (counter === 4) {
      return clearInterval(SendingMessage); //<-- clear the interval when reach 5.
  }
  counter++ //<-- counter increment.
  
}, 1500);
