javascript

function sendEmails() {  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();  var data = sheet.getDataRange().getValues();    var smtpServer = "smtp.example.com"; // Replace with your SMTP server  var smtpPort = 465; // Replace with your SMTP port  var smtpUser = "your-email@example.com"; // Replace with your SMTP email  var smtpPassword = "your-password"; // Replace with your SMTP password    for (var i = 1; i < data.length; i++) { // Start from 1 to skip header row    var email = data[i][0];    var name = data[i][1];    var message = data[i][2];        var emailBody = "Dear " + name + ",\n\n" + message + "\n\nBest regards,\nYour Company";    sendSMTPMail(email, "Personalized Email Subject", emailBody, smtpServer, smtpPort, smtpUser, smtpPassword);  } } function sendSMTPMail(recipient, subject, body, smtpServer, smtpPort, smtpUser, smtpPassword) {  var auth = {    'method': 'post',    'headers': {      'Authorization': 'Basic ' + Utilities.base64Encode(smtpUser + ':' + smtpPassword)    },    'payload': {      'to': recipient,      'subject': subject,      'body': body,      'smtpServer': smtpServer,      'smtpPort': smtpPort    }  };  var url = 'https://api.mailgun.net/v3/YOUR_DOMAIN/messages'; // Replace with your mail sending API URL  UrlFetchApp.fetch(url, auth); }
