Send an Email

To send a message to the rest of the group, just address an email to groupname@yahoogroups.com, substituting the actual name of your group for "groupname." Group names are not case sensitive.

Note: you can only post to groups you've joined, and only from email addresses registered with Yahoo! Groups. If you misspell the name of a group, or attempt to send an email from an account other than the one you joined under, your message won’t be delivered. If you receive a failure notice, check your email addresses and try again.

Post from the Yahoo! Group Web Site

After you've signed in, go to the group you wish to post to, and click Post. Write your message, and then click Send Message.

Note: Yahoo! Groups restricts messages to 15 megabyte in size to prevent abuse. This includes both the message body and the attachment. Email clients and ISPs sometimes add additional kilobytes to messages, so to be safe, send messages that are smaller than a 15MB.
