What percentage of deliveries is required for ECRWSS to achieve saturation?

ECRWSS stands for Every Door Direct Mail - Retail Saturation Service, which is a service provided by the United States Postal Service aimed at helping businesses reach all the households in a designated area without needing a mailing list. Achieving saturation means that the mail is reaching the majority of potential customers in a specific geographic area. The correct percentage for saturation in this context is 75% total deliveries. This figure is significant because it allows businesses to connect with a large segment of the population effectively without the need for individual addresses. Reaching 75% of total deliveries ensures that the marketing efforts are efficient and that the potential response from the community is maximized, making full use of the ECRWSS strategy.
