What is the requirement for mailpieces using a simplified address for ECRWSS?

The requirement for mailpieces using a simplified address for Every Door Direct Mail - Retail (ECRWSS) is that they must achieve 100% delivery. ECRWSS is designed to allow marketers to reach every household on a mailing route without needing specific names or addresses, thus requiring that the mailpieces reach all residential locations on that route. This ensures that the promotional materials or ads are distributed to the entirety of the targeted area, maximizing outreach and ensuring that no households are missed.

While other options might highlight varying levels of delivery or requirements, they do not align with the fundamental principle of ECRWSS, which is aimed at ensuring comprehensive delivery to all residences within the designated area. This full coverage is essential for the effectiveness of campaigns utilizing simplified addressing under this program.
