Crest Mailings · Match and merge

Checked against the source, not assumed.

A job opens with criteria that can be counted, not adjectives. Gaps are measured and reported, not interpolated. Whatever was taken out ships beside whatever was left in.

Scope agreement

Turning a written requirement into countable criteria, and confirming the size before any records are assembled.

Validation

Checking structure and reachability before a file is used, not after.

Outlier review

Looking at the extremes of each field, because that is where bad data announces itself.

Describe the exclusions as well as the targets; both shape what is possible.
