|Inviting All Your Friends||Sending a Personalized Invitation|
The most efficient way to invite your friends to use Messenger is to send an email invitation to all of them at once. You can have Messenger search through your Yahoo! Contacts and other email and address book applications that you use to gather a list of emails. Then, you can have Messenger send one invitation to all of your email recipients.
This process is part of Messenger’s importing contacts feature, which you can find detailed in the Adding Contacts to Your Messenger List tutorial.
Want something a bit more personal? Use Messenger’s invitation feature and pen a few words to add to the invite.
