Protecting your inbox from spam, phishing attempts, and unsolicited marketing is crucial for maintaining digital productivity. While Gmail possesses an incredibly robust automatic spam filter, sophisticated unwanted emails can occasionally slip through into your primary inbox. If you are receiving persistent, unwanted emails from specific addresses or entirely unknown senders, you can take manual action to block them permanently.
Blocking a Specific Sender
The most direct way to stop receiving emails from an unknown sender is to use Gmail’s built-in blocking tool. This action tells Google to automatically route any future emails from that specific email address directly into your Spam folder, bypassing your inbox entirely.
- Open Gmail in your web browser or via the mobile app.
- Locate and open the unwanted email from the sender you wish to block.
- Look at the top right corner of the email itself (next to the Reply arrow), and click the More icon, represented by three vertical dots.
- From the drop-down menu, select Block “[Sender Name]”.
- A confirmation pop-up will appear warning you that future messages from this address will be marked as spam. Click the Block button to confirm.
If you ever need to unblock someone, you can navigate to Settings (gear icon) > See all settings > Filters and Blocked Addresses, locate the email address in the list at the bottom of the page, and click “Unblock”.
Creating a Filter for Broader Blocking
Blocking individual senders works well for persistent individuals, but spammers often use slightly different email addresses for every message (e.g., [email protected], [email protected]). In these cases, blocking a single address is ineffective. Instead, you need to create a filter to block an entire domain.
- Open Gmail on a desktop browser.
- Click the Show search options icon (it looks like a slider menu) located on the far right side of the main search bar at the top of the screen.
- In the From field, type the domain you want to block, preceded by an asterisk (e.g.,
*@spamwebsite.com). The asterisk acts as a wildcard, meaning “any email address ending in this domain.” - Click the Create filter button at the bottom of the search panel.
- Check the box next to Delete it. (Alternatively, you can choose “Skip the Inbox” and apply a specific label if you want to review them later, but “Delete it” sends them straight to the bin).
- Click the blue Create filter button.
Reporting Spam and Phishing
If the email from the unknown sender appears to be malicious (e.g., asking for passwords, banking details, or containing suspicious links), simply blocking the sender is not enough. You should actively report the email to Google to help improve their global spam filters.
Open the malicious email, click the three vertical dots next to the reply button, and select Report phishing or Report spam. This action not only removes the email from your inbox but also alerts Google’s security team to investigate the sender, potentially protecting millions of other Gmail users from receiving the same malicious email.
