Do you send regular emails to a group of people, like family members, business colleagues, or social groups? You can use a discussion groups service to create a single email address that will reach everyone in the group, so you don’t have to type them all in every time. Once you’ve set up a group online and added members, any member can use the group address to send emails to the whole group. The emails are archived on the web so you can view them and search their contents at any time. Both Google and Yahoo provide this service at no cost.
