Mailmark® is a Royal Mail service that integrates mail with technology and business intelligence. It uses barcode technology to enable detailed reporting on mail performance, including:
- Batch-level insights: Predicted delivery dates, volumes, and performance metrics.
- Item-level error reporting: Identifies issues with individual mail items.
It is designed for high-volume, machine-readable mail, offering tools for businesses to analyse and optimise their mailing operations.
Mailmark reporting is available to customers in two forms:
1. PDF reporting - we provide, upon request, Mailmark customers with details of the performance of their mailings through provision of a PDF file. We have developed a user guide to assist customers with:
- requesting Mailmark PDF reports;
- understanding those reports; and
- identifying opportunities to collate reports through an existing common Participant ID.
2. Mailmark Direct Data transfer service - this provides Mailmark customers automatically with supply item data on all your Mailmark items. We have set up a dedicated Mailmark Direct Data page at which you will find some useful technical specifications.
