Beacon Mailers

Where each record came from, and when.

The brief is the specification, and it is written before the build. The same record arriving twice is collapsed, and which copy won is recorded. Lineage survives the handover rather than being stripped at the door.

Date normalisation

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

Recency statement

Saying how old each part of a file is, so decisions about what to use are made with that in view.

Sending identity

Separating what you send in volume from how your main domain is treated.

Ask for a sample first. It is the quickest way to find out whether this is useful.
