Bright Mailers

Ask what is missing. We will have written it down.

The first question is always who counts as in scope. The build is repeatable, because the rules are written rather than remembered. You can tell, from the file alone, what was checked and what was assumed.

Classification check

Verifying categories against the underlying description rather than trusting a label applied upstream.

Suppression handling

Applying exclusion lists before counting, so the approved figure and the delivered figure are the same number.

Second-opinion pass

Having somebody who did not build the file check it against the brief.

A brief in your own words beats a template.
