1. Go to Junk email, then choose Safe senders and domains or Safe mailing lists to select the domain or email you want to whitelist.
2. Enter the domain name or email address you wish to add to Safe senders. Make sure to include the @ character for domain names in order to only whitelist emails with the exact string of characters you entered (and nothing more).

Alternatively, you can simply add an individual email address that has sent you a message to your Outlook Contacts. Though they lead to the same result, this method is quicker and more efficient than manually entering information.

How to Whitelist an Email in Yahoo Mail

If you want to move a sender or domain name to your whitelist Yahoo Mail, the process is even easier than it is in the other service providers mentioned above.

As long as you have already received at least one message from the address in question, all you have to do is highlight that message in the Bulk folder and mark it as Not Spam. Once you have identified a single message from a given sender, the Yahoo Mail spam filters will automatically allow future messages from the same address into your inbox.

On the other hand, if the person you’re attempting to whitelist hasn’t yet sent you a message, you’ll need to go through the following steps to whitelist the address:

1. Navigate to Settings icon, then click More Settings from the Yahoo Mail menu.
2. Select Filters and hit Add new filters to enter information about the domain name or sender.
   

1. From here, you can enter any string of text you want to whitelist in future emails. This could be anything from an email address or domain name to something you expect to be in the body of the message.
   

Yahoo Mail makes it much easier to whitelist a domain name or email sender once they’ve already sent a message to you that’s located in your Bulk folder, so consider asking the person you’re trying to whitelist to send you a test email in advance.

How to Whitelist an Email Address in AOL

Many people looking for email whitelisting instructions for AOL are confused by the fact that AOL doesn’t have a traditional email whitelist. Instead, it considers all mail addresses a user has in his or her address book to be trustworthy. This means that the contact list in AOL essentially serves the same purpose as Gmail whitelist and Outlook whitelist.

1. Log in to your AOL account.
2. Open Contacts from the left navigation pane.
3. Click the New Contact icon and enter the required information.
4. Click the Add Contact button located at the bottom.

As you can see, the entire process is straightforward, and deleting existing contacts is similarly easy. All you need to do is select the contact you want to delete and click the Delete button at the top of the page. If you want to block the deleted contact, you need to go to Options -> Mail Settings -> Spam Settings. There, you can add the contact to your email blacklist.
