How to Block Casino and Betting Emails in Microsoft Outlook (Desktop) — Step-by-Step Guide

Why block casino emails in Outlook?

If you use your work email or a personal account configured in Outlook desktop, you may receive promotional emails from casinos there too — especially if you ever registered with that address. Outlook's filtering rules are powerful and let you delete these emails before they even reach your inbox.

Step 1 — Open the Rules Wizard

• Open Outlook on your computer.
• Go to the top menu and click "File".
• Select "Manage Rules & Alerts" (in the Info section).
• Click "New Rule...".

Step 2 — Set up the condition

• In the wizard, select "Apply rule on messages I receive".
• Click "Next".
• Tick the checkbox "with specific words in the subject or body".
• At the bottom of the wizard, click the blue "specific words" link.
• A dialogue box will open. Type a keyword and click "Add". Repeat with each of the following:

• Once you've added all the keywords, click "OK".
• Click "Next".

Step 3 — Set up the action

• Tick the "delete it" checkbox (this moves the email to the Deleted Items folder).
• Optionally, also tick "stop processing more rules" to avoid conflicts with other rules.
• Click "Next".

Step 4 — Set up exceptions (optional)

If there are legitimate senders who might use some of these words (for example, a sports newspaper you read), you can add exceptions:

• Tick "except if from people or public group" and select the trusted senders.
• If you don't need exceptions, simply click "Next".

Step 5 — Name and activate the rule

• Give the rule a descriptive name: "Block casino emails".
• Tick the "Run this rule now on messages already in Inbox" checkbox to clean up existing emails.
• Make sure the "Turn on this rule" checkbox is ticked.
• Click "Finish" and then "OK".

Step 6 — Block senders directly

To quickly block specific senders:

• Right-click on a casino email in your inbox.
• Select "Junk" → "Block Sender".
• Outlook will automatically add that address to your blocked senders list.
• Repeat this for every casino email you find.

Step 7 — Advanced management: block entire domains

To block all emails from a casino domain (for example, all emails from @888casino.com):

• Go to Home → Junk → Junk E-Mail Options.
• Go to the "Blocked Senders" tab.
• Click "Add" and type the domain (e.g.: @888casino.com, @bet365.com).
• Repeat for each operator domain you know.
• Click "OK".

Step 8 — Final cleanup

• Use Outlook's search bar (Ctrl + E) and search for "casino", "bet", "bonus". Select all results and delete them.
• Empty the Deleted Items folder: right-click → "Empty Folder".
• Check the Junk Email folder and do the same.

Ongoing maintenance

Gambling operators frequently change their sending domains and the terms they use to evade filters. We recommend:

• Review your rules once a month (File → Manage Rules & Alerts).
• If a casino email slips through, block the sender immediately and add new keywords to your rule.
• Keep casino and betting apps uninstalled from your phone.

Additional protection
