Internet Basics: Email Marketing is Like Butterfly Pheromones

Pheromones are chemicals that butterflies and other insects release to communicate over long distances. In the case of butterflies, they can release a pheromone to announce they're available for mating. Within a short period of time, another butterfly gets the pheromone message and suddenly, the two butterflies have hooked up. And all is good. That's what email marketing is like.
