Although more expensive to implement than digital marketing strategies, a direct mail campaign offers certain advantages. For one, certain segments of the population are still not internet-savvy. When offering a service that would benefit older persons and those not familiar with online advertising, direct mail is a far more effective strategy. It also tends to have a longer reach, as a piece of direct mail may sit on a consumer's desk for months, warranting many glances. For optimal direct mail effectiveness, include a self-addressed stamped envelope to invite a consumer response.
