Saikat Basu Updated 28-01-2020

Knowing how to use the block and unblock feature on Gmail is one of the drawbridges you have to protect your inbox. Blocking and unblocking your contacts in Gmail is a simple matter of two clicks.


When you block a contact, messages from their addresses will end up in your Spam folder, but they won’t know they were blocked. And don’t forget to unblock them if you just wanted to temporarily block them for a while.

How to Block All Emails From a Domain With a Rule

Like individual email addresses, you can “block” all emails from specific domains too. But in this case, you have to create a rule that will delete incoming mails from that domain as they hit your inbox.

It’s a timesaver as you don’t have to add individual contacts from that domain to your own Gmail’s blocked list one by one. Here’s how to create a rule that will filter and block all emails from a specific domain automatically:


1. Go to Gmail settings (by clicking the gear icon).

2. Click the Filters and Blocked Addresses tab.

3. Click Create a new filter.

5. Click Create filter with this search.

7. Click Create filter.

You can also take a shortcut to these filter settings by using a single email from the domain.

  1. Open Gmail.
  2. Check the checkbox next to the email you want.
  3. Click More > Filter messages like these.
  4. Enter your filter criteria.
  5. Click Create filter.

Note: When you create these rules to filter out unwanted emails, only new emails will be affected. You have to click Also apply filter to [X] matching conversations to affect the older mails in your inbox that match the criteria.

All deleted emails are available in the Trash for 30 days. You can manually check the trash folder for any important mail caught by the filter.

Unblock the domain by deleting the rule. Go to Settings > Filters and Blocked Addresses. Select the filter in the list and click on Delete.
