To stop those emails in Outlook.com:
- Open Settings.
- Go to Mail > Subscriptions.
- Under Your current subscriptions, find Window Nation.
- Select Unsubscribe.
- Confirm by selecting OK.
If unsubscribe is not available, block the sender instead:
- Go to Settings > Mail > Subscriptions.
- Select the three dots next to the sender.
- Select Block <sender>.
- Select OK.
Blocked senders can also be reviewed in Settings > Mail > Junk email.
For Microsoft promotional emails, communication preferences can be managed in the Microsoft account profile, but required service emails such as billing and security notices will still be sent.
