Step-by-Step: Gmail to PDF by Specific Sender
✅ Step 1: Open Google Apps Script
Go to https://script.google.com.

Click "New Project."

✅ Step 2: Paste this optimized sender-specific script:
Replace "sender@example.com" with your target sender’s email address:


function emailsFromSenderToPDF() {
  var senderEmail = "sender@example.com"; // Replace with sender's email

  // Search Gmail specifically by sender
  var threads = GmailApp.search("from:" + senderEmail);

  var folderName = "Gmail PDFs - " + senderEmail;
  var folder, folders = DriveApp.getFoldersByName(folderName);
  if (folders.hasNext()) {
    folder = folders.next();
  } else {
    folder = DriveApp.createFolder(folderName);
  }

  for (var i = 0; i < threads.length; i++) {
    var messages = threads[i].getMessages();

    for (var j = 0; j < messages.length; j++) {
      var message = messages[j];

      // Confirm sender explicitly matches
      if (message.getFrom().includes(senderEmail)) {
        var subject = message.getSubject().replace(/[^a-zA-Z0-9 ]/g, '');
        var date = Utilities.formatDate(message.getDate(), "GMT", "yyyy-MM-dd");
        var filename = date + " - " + subject + ".pdf";

        // Convert email body to PDF
        var blob = Utilities.newBlob(message.getBody(), "text/html", filename).getAs("application/pdf");

        // Save to Google Drive
        folder.createFile(blob);
      }
    }
  }
}

What this does clearly:

✅ Finds all emails matching exactly your chosen sender.

✅ Converts each email into a PDF.

✅ Stores PDFs in a folder labeled specifically for that sender.

✅ Step 3: Run your script:
Click the ▶️ Run button at the top.

The first time, authorize the script (click "Review permissions" and allow).

📂 Step 4: View your PDFs:
Go to your Google Drive.

Open the folder named Gmail PDFs - sender@example.com.

All sender-specific emails are organized as PDFs, neatly timestamped.
