Lists Wave · Data briefs
Preparation, rather than procurement.
The first pass is deliberately narrow, and widened only on request. Records are aged as well as counted, because staleness varies by field. Anything that could not be filled is stated plainly rather than padded.
Source arbitration
Deciding which origin wins when two disagree about the same organisation, and recording the decision.
Sample first
A small extract to check against before the full build, so a misread brief costs nothing.
Prior-contact exclusion
Taking out anyone already written to, from lists you supply as well as our own record.
If nothing suitable exists, you will hear that first rather than last.
