For each group you belong to, you can choose one of these message delivery options:

• Individual Emails
  Messages are delivered one at a time to your email inbox. This is the best option if you want to keep up on the latest posts immediately. Email attachments, if included in a message and allowed by your moderator, will be sent directly to you.
• Daily Digest
  Messages are delivered in batches of 25 or daily, whichever comes sooner. This is the best option if you want to receive fewer mail messages and don't need up-to-the minute posts in your inbox. Email attachments are not available in digests.
• No Email
  This option puts email message delivery on hold, for example while you’re on vacation. If message archives are available, this option also permits you to read messages at the Yahoo! Groups web site. Note that message archive options are determined by each moderator, and that some groups have no web message archives.
• Special Notices
  This option is similar to No Email because you won’t receive normal group messages. You’ll, however, be able to receive Special Notices sent by the group's moderator.

To change any of these options, click My Groups in the upper-right corner of any groups page, then, above the list of groups, click the Edit My Groups tab. Under Message Delivery, you’ll see pull-down menus where you can specify how you’d like to hear from that group. Make sure to click Save Changes if you change anything.
