Free Tell a Friend is a free service to allow your visitors to share your website with their friends. The idea is simple; you place a ‘tell a friend’ button on your website, and when your visitor decides to tell their friend about your website, they click this button which then presents them with a straightforward form to e-mail their friends.
The great addition to FreeTellaFriend is your visitor can enter their e-mail username and password and system will automatically retrieve their contact list. Thereafter they can choose who to e-mail the website to. If one user decides to e-mail all their contacts, your website will be exposed to over 50 friends (on average).
They support all major E-mail Providers :
