Launch Mailers

Schema alignment

Scoped, assembled, and reported on.

Criteria are drafted, reviewed and fixed before assembly starts. The same record arriving twice is collapsed, and which copy won is recorded. The handover includes what was removed, and why it was removed.

Universe sizing
Establishing how many records satisfy the criteria before anyone decides whether the job is worth running.
Geography resolution
Working out which location a record belongs to when it carries several addresses.
Jurisdiction split
Separating records by the rules that apply where the person is, not where the file was built.

Any brief that can be written down can be counted, and that comes first.
