If you are an email2 user, and you belong to a PEN, you might be able to invite your friends or associates to email2. As long as your PEN is accepting new members, you simply need to send someone an email2 message - even if they don't have the toolbar installed.

If a friend or associate receives an email2 message and he or she doesn't have the toolbar installed, an invitation and link to download it will be provided. If the recipient has the toolbar installed, but he or she isn't a member of your PEN, the email2 message which you sent will allow them to join the PEN.

Alternatively, you could log into the email2 Web Client and invite someone using the "Invite Friends" button.
