Our Solution

Accuracy built into every insertion job.

Mail insertion is one of the most critical stages in any direct mail campaign.

Mechanical insertion brings multiple components together at speed. Each job needs to be carefully set up so the correct items are folded, collated and inserted into the right envelope.

DMC combines high-speed insertion equipment with structured workflows, selective insertion and quality checks throughout production.

This supports accurate, consistent output across simple letters, multi-piece campaigns and matched mailings at scale.
