Step 2: Write the Script

Here's a script to extract email addresses from Gmail messages:

javascript

function extractEmailAddresses() {  var threads = GmailApp.search('your search criteria');  var emailAddresses = [];    for (var i = 0; i < threads.length; i++) {    var messages = threads[i].getMessages();        for (var j = 0; j < messages.length; j++) {      var from = messages[j].getFrom();      var match = from.match(/<([^>]+)>/);            if (match) {        emailAddresses.push(match[1]);      }    }  }    // Remove duplicates  emailAddresses = Array.from(new Set(emailAddresses));    // Log the email addresses  Logger.log(emailAddresses);    // Optionally, write the email addresses to a Google Sheet  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();  sheet.getRange(1, 1, emailAddresses.length, 1).setValues(emailAddresses.map(function(email) { return [email]; })); }
