Yahoo! Groups

Yahoo! Groups was a free-to-use system of electronic mailing lists offered by Yahoo!.

Prior to February 2020, Yahoo! Groups was one of the world's largest collections of online discussion boards. It allowed members to subscribe to various groups, read subscribed discussions online, view and share photos, files and bookmarks within a group, access a group calendar, create polls for group members, and receive email notifications of new discussion topics. Some groups were simply announcement boards, to which only the group moderators could post, while others were discussion forums. Depending on each group's settings, membership could be open to everyone or only to invited or approved people.

Groups, OneList had millions of subscribers and was sending out billions of emails per month
