First, confirm that the group exists and that you’re a member. Visit your My Groups page and look for the group name.

If the group name doesn’t appear, one of the following may have happened:

• You were unsubscribed from the group.
• The group was deleted.
• Your email account bounced email and is now in bouncing status.

If the group name does appear, check the following:

• Check your subscription to that group (click Edit Membership in the upper left), and make sure it’s set to Daily Digest or Individual Emails in the Message Delivery section.
• There may be a problem with your Yahoo! Groups account. If there is an "Email account is bouncing" error message near the top of the page, click on the link for details. If there is no bounce error message, please contact our Customer Support team with the following information:
• the email address you used to register with Yahoo! Groups
• the names of one or more groups you joined
• the date you stopped receiving emails from the group(s)
• Did you recently change your email address? Make sure you entered it correctly and that the email address you entered is valid and operational. Also, make sure that you’ve replied to the Yahoo! Groups confirmation message.
• There may be a problem with Yahoo! Groups systems or the connection between Yahoo! Groups and your ISP (or your email client if you use a web based email account like Hotmail or Gmail). In these situations please contact your ISP or Web Email Host to encourage them to work with the Yahoo! Groups team to resolve the issue. They can communicate with the Yahoo! Groups Email Delivery team by joining this group: http://groups.yahoo.com/group/ygmailadmin/
• If you’re no longer getting emails from your group — even though you know from the web site that messages are being posted — it may be that your email client or ISP is mistakenly identifying Groups email messages as spam. Check your "bulk" or "spam" folder to see if messages are being redirected there. If they aren't, contact your email provider to ensure that messages are being delivered.
