They use viral marketing by e-mail as a marketing tool… what did you think I meant? Viral marketing can work well for B2B providers, as long as the following is true:
1. The product or service has to add value for the sender, as well as, the receiver.
2. The offer has to be deliverable. You don’t want to offer a product that you can’t deliver if demand grows rapidly.
3. The offer has to be easily transferable to others. E-mail and Web pages provide the best medium to facilitate this.
4. The best viral marketing campaigns use existing networks to move the message along.
