How to Block Spam Emails on Gmail and Clean Storage

G GOWTHAM
Spam emails can clutter your Gmail inbox, make it hard to find important messages, and even fill up your storage. Fortunately, Gmail provides tools to block unwanted emails, mark spam, and clean storage efficiently. Here’s a complete step-by-step guide.

1. Block Specific Email Addresses

If you keep receiving emails from a particular sender:

Open Gmail on desktop or mobile app

Open an email from the sender you want to block

Click the three-dot menu (top-right corner of the email)

Select “Block [Sender Name]”

Future emails from this address will automatically go to Spam

2. Mark Emails as Spam

  • Gmail’s spam filter works better when you mark emails as spam manually.
  • Steps:
Open the unwanted email

Click “Report Spam” (on desktop) or tap three dots → Report Spam (on mobile)

  • Gmail will learn to filter similar emails automatically
3. Unsubscribe from Mailing Lists

  • Many promotional emails include an unsubscribe link at the bottom.
  • Steps:
Open the email

Click “Unsubscribe”

  • Gmail may also show an “Unsubscribe” button next to the sender in the inbox for easy removal
4. Use Gmail Filters to Automatically Manage Emails

  • Gmail filters help automate blocking, labeling, or deleting certain emails.
  • Steps:
Go to Settings → See all settings → Filters and Blocked Addresses → Create a new filter

Enter the email address, domain, or keywords

Choose actions like Delete, Skip Inbox, or Apply Label

Save the filter

5. Clean Gmail Storage

  • Gmail storage is shared with Google Drive and google Photos. Cleaning unwanted emails helps free space.
  • Tips:
    • Search for emails with large attachments: has:attachment larger:10M
    • Delete unnecessary emails in Promotions, Updates, and Social tabs
    • Empty the Trash folder after deletion
6. Additional Tips

  • Use Gmail’s Spam folder to review blocked messages once in a while
  • Avoid clicking suspicious links in emails to prevent phishing
  • Consider archiving emails instead of deleting if you might need them later
