Steps to Whitelist an Email in Gmail
If Gmail is your email provider, preventing specific messages from ending up in your spam folder is straightforward. By setting up spam filters, you can ensure future communications from a particular sender are never marked as spam. Here's how you can quickly whitelist emails in Gmail through the web client:
- Log into your Gmail account.
-
Click the Settings gear icon in the top-right corner, then select "See all settings."

-
Navigate to the Filters and Blocked Addresses tab to view your existing filters. Then, select "Create a new filter."
💡 Tip: To whitelist a specific sender, enter the entire email address. To whitelist all emails from a particular domain, simply enter the domain (e.g., “@yahoo.com”). This ensures that all emails from that domain are approved.
-
In the "From" section, type the email addresses or domains you wish to add to the Gmail whitelist. Click "Create filter" to confirm.
- Click Create filter to confirm.
-
Check the box next to "Never send it to Spam" to add the address to your Gmail safe sender list.
-
Click "Create filter" again to save your settings.
Utilizing Gmail's filter settings, you have the ability to star emails, assign a specific label, mark them as important, or take other actions.
Whitelisting in Gmail mobile app
Although the Gmail mobile app doesn't support creating advanced filters, you can still whitelist senders from your spam folder:
-
Open the Gmail app.
-
Navigate to the Spam or Junk folder.
-
Tap on the message you want to view.
-
Select the option "Report not spam." From now on, you'll receive emails from this sender in your inbox.
Steps to Whitelist an Email in Outlook
To whitelist an email domain or a specific address in Outlook.com, you need to add it to the Safe senders group. A whitelisted address will bypass Outlook's spam filters and go directly to your inbox. Here’s how you can add an address or domain to the Safe senders list:
-
Sign in to your Outlook inbox on the web.
-
Click the gear icon in the top right corner to access Settings.
-
On the left sidebar, select Mail, then navigate to Junk email.
-
Under Safe senders and domains, click +Add to include a contact in the allowed list.

Enter the email address or domain name you want to whitelist. Be sure to include the "@" character for domain names.
Alternatively, you can add an individual address directly to your Outlook Contacts if they have sent you an email. This method is quicker and more efficient than manually entering the information.

Once you mark the email as not spam, Yahoo's spam filter will automatically allow future messages from that address into your inbox.
However, if the sender hasn't yet sent you a message, follow these steps to whitelist the address:
-
Navigate to the Settings icon and click on "More Settings" from the Yahoo Mail menu.
-
Select "Filters" and click "Add new filters" to enter information about the domain or sender.

Here, you can enter any text you want to whitelist in future emails. This could be an email address, a domain name, or specific content you expect to see in the message body.

- Fill in the details and save the filter.
