Vantage Lists

Criteria you could defend to a colleague.

Nothing is assembled before the target is described in writing. Categories are checked against the underlying description, not the label attached upstream. Rather than a percentage, you get the numbers the percentage was made from.

Exclusion log

A record of what was removed and why, delivered alongside the file it came out of.

Monitoring

Watching for the configuration changes that quietly stop mail arriving.

Date normalisation

Putting every date in one format and one timezone before any comparison runs.

Counts cost nothing and take about a day.
