There are a number of reasons why you might receive email that appears to be from Yahoo!, even after unsubscribing:

You might have received an administrative announcement.
You can't unsubscribe or opt out from receiving administrative service announcements, such as notifications of changes in our terms of service or privacy policy. Administrative announcements might also include billing and service status notices, telling you a service is being discontinued or providing updates on service outages.

• Each email Yahoo! sends explains why it was sent to you. The email identifies itself as an administrative announcement or other service email and states what service it relates to.

You might have unsubscribed from another category of email sent by Yahoo!.
Yahoo! sends different emails about different topics and for different reasons. Please verify you unsubscribed from the type of email that you received.

• Each email Yahoo! sends identifies why it was sent to you. Most often, that information is included in the email footers.
• Email that markets a Yahoo! product or service: Visit the Marketing Preferences page and verify you are unsubscribed from the categories of email you don't want to receive.
• Yahoo! Newsletters: Visit the Newsletter Management page to verify you are unsubscribed from the newsletters you don't want.

Your changes take effect within 10 business days.
If you recently unsubscribed, the email you received might have been processed and ready to mail when you updated your preferences.

Spam
A lot of spam and other unsolicited email "spoofs" Yahoo! email accounts.

• In spoofing, the address that appears in the "From" field is one that never existed or that doesn't belong to the sender. To convince people to open the email, spammers might even use official-sounding email addresses like support@yahoo.com. Unfortunately, current email technology allows people to send email that appears to be from anyone else, such as president@whitehouse.gov. We have been working to limit this and develop methods to verify email senders.
• We don't like spam either and have set up an Anti-Spam Resource Center.
• We've also made a technology proposal called Domain Keys, which gives email providers a mechanism for verifying both the domain of each email sender and the integrity of the message sent.
• Remember, a legitimate email message from Yahoo! never asks you to provide personally identifying information in the email message or request a reply email with this type of information.

Note: Yahoo!'s Marketing Preferences and other unsubscribe tools only apply to email sent to you from Yahoo!. These preferences and tools do not affect email sent through Yahoo! servers on behalf of other people who use "Tell a Friend" forms; emails sent through Yahoo! Mail, Yahoo! Groups, and other services; or spam email sent using invalid or fake Yahoo! Mail addresses.

• Learn how to report spam.
• Edit the email delivery options for Yahoo! Groups you belong to.
• Edit any Yahoo! Alerts you created.
