I have tried for more than 2 hours to figure out how to send a weekly email to a group. I have the names/addresses in the group, but don't understand how to get them to the bcc "to" line in the "compose" mode of my email.
Click the blue "Show BCC" on the right side to open the BCC address area. Type the group name into the box and it should populate the box with all the group recipients' email addresses. Hope this is what you're looking for.
