How to add email addresses to the safe/blocked senders list in Outlook?
Outlook’s "Junk Email Filter" helps protect you from spam, but it isn’t always accurate. Sometimes, legitimate emails end up in the Junk Email folder, while unwanted emails still reach your inbox. If important emails are consistently marked as spam, you can whitelist trusted senders by adding them to the "Safe Senders list". Similarly, if spam or unwanted emails frequently appear in your inbox, adding them to the "Blocked Senders list" ensures they are filtered out automatically.
This article introduces three methods to achieve this, with "Kutools for Outlook" recommended for its efficiency in handling multiple addresses at once.
Add a single email address to the safe/blocked senders list (Basic & Manual)
Add multiple email addresses to the safe/blocked senders list instantly with Kutools for Outlook 👍 (Effortless & Recommended)
Manually add email addresses to the safe/blocked senders list via Junk E-mail Options (Flexible & Manual Input)
Add a single email address to the safe/blocked senders list
Outlook provides two built-in features—"Never Block Sender" and "Block Sender"—that allow you to quickly add an email address to the safe senders or blocked senders list.
1. Select the email from the sender you want to add to the "Safe Senders list," then click "Home" > "Junk" > "Never Block Sender."
2. A confirmation box will appear, notifying you that the sender's address has been added to the list. Click "OK" to close the dialog.
Limitations of This Method:
- One address at a time: Cannot add multiple addresses at once, making it inefficient for bulk management.
- Requires an email from the sender: Cannot manually add addresses; use Junk E-mail Options for manual entry.

Manually add email addresses to the safe/blocked senders list via Junk E-mail Options
If you don’t have an email from the sender but know their email address, you can manually add addresses through "Junk E-mail Options" in Outlook.
1. Click "Home" > "Junk" > "Junk E-mail Options."
2. In the "Junk E-mail Options" dialog, go to the "Safe Senders" tab and click "Add."
3. In the "Add address or domain" box, enter the email address you want to whitelist and click "OK."
4. Click "OK" to save changes and close the "Junk E-mail Options" dialog.
Additional Settings for Safe Senders:
- Trust contacts automatically: Check "Also trust email from my Contacts" to ensure all contacts in your Outlook address book are treated as safe senders.
- Automatically whitelist people you email: Check "Automatically add people I email to the Safe Senders List" to prevent emails from your recipients from being marked as junk.
Limitations of This Method Compared to the Kutools for Outlook Method:
While the "Junk E-mail Options method allows manual management of safe and blocked senders, it has key drawbacks compared to Kutools for Outlook:
- Manual entry: Each email address must be typed or copy-pasted individually.
- No batch processing: Only allows adding addresses one by one.
- Time-consuming for large lists: Inefficient if handling many addresses.
- Slower process: Requires navigating multiple dialog boxes.
- Higher risk of errors: Typing manually increases the chance of typos.
