Read and respond to posts in email
If your group is set up as an email list, you’ll probably read the group’s content in email. Simply email the group. Group members can see your email messages in their email, on the forum interface (which serves as an email archive), or both.
To set this up:
Go to your My groups page and click the Edit memberships button. You'll see the Manage memberships page, showing all the groups you're a member of. For example:
In the drop-down list for a group, choose an email subscription option:
No email: You won't receive messages to the group in your Inbox. You can visit the group's forum to read and respond to messages. (You can do that if you choose to get email, too.)
Abridged email: Once a day, you'll get a summary of new messages.
Digest email: Once a day, you'll get full email messages bundled into a single message.
- All email: You'll receive each message sent to the group separately.
