How to Automatically Delete All Emails from a specific Sender on Gmail

Are you overwhelmed by emails from a particular sender? Maybe it's an old newsletter or automated alerts you no longer need. If you're looking for a quick, repeatable way to select and delete all emails from a specific address, Google Apps Script can help.

🔧 Step-by-Step: Writing the Script

1. Open Google Apps Script
• Go to https://script.google.com
• Click "New Project"

2. Paste the following code:

function deleteEmailsFromSender() {
  const senderEmail = "someone@example.com"; // 🔁 Change this to the sender's email
  const query = `from:${senderEmail}`;
  const threads = GmailApp.search(query);
  
  Logger.log(`Found ${threads.length} threads from ${senderEmail}`);
  
  for (let i = 0; i < threads.length; i++) {
    threads[i].moveToTrash(); // 💥 This deletes the email threads
  }
  
  Logger.log("Finished deleting emails.");
}

• Save the project
• Click on the filename (e.g., "Untitled project") and name it something like DeleteEmails.

• Run the Script
• Click the Run ▶️ button
• The first time, you’ll be asked to authorize permissions—follow the prompts

• Check Gmail Trash
• Go to Gmail and open the Trash folder
• All emails from the sender should now be there, ready to be permanently deleted

⚠️ A Few Important Notes

• This script moves emails to Trash, not permanently deletes them. Gmail will auto-delete Trash emails after 30 days, or you can manually empty Trash sooner.

• Be careful: there’s no “undo” button once emails are moved to Trash!

• You can schedule this script to run regularly using Triggers (see below).

⏰ Bonus: Automate with a Time Trigger

1. In the Apps Script editor, click Triggers (⏰ icon in left sidebar)

2. Click "+ Add Trigger"

3. Choose:
• Function to run: deleteEmailsFromSender
• Event source: "Time-driven"
• Set frequency (e.g., daily or weekly)

4. Click Save

✅ Summary

• Find all emails from a specific address

• Move them to the Trash in one go

• Automate the process with a time-based trigger
