Viral Email is one of the favorable tools in the Creative Tank arsenal of viral marketing techniques.

Using 'Send to a friend' techniques often trigger initial recipients to send on a message to appropriate recipients. It is usually essential that the recipient is encouraged to pass on the message by receiving an award after they have passed in on. This for example, may be in the form of a competition, voucher, or industry white paper. This is often a good opportunity to collect further information on the recipients as part of a long turn marketing strategy.
