Address quality is a sequence of decisions, and most organizations are missing at least one.
Is the address valid at the point of entry?
Does it reflect recent changes before the file goes to print?
Is return mail used to update records, or is it just processed and discarded?
Is the feedback loop closed, or does the same bad address reappear in the next campaign?
Adam Collinson’s Understanding Address Quality series walks through the full lifecycle: what address quality actually means, how it degrades, what each intervention can and cannot do, and what a well-governed postal data operation looks like in practice.
