What Mailmark actually is
A machine-readable barcode printed by compatible franking machines. It replaces the traditional franking impression and carries data about the mail item.
Not all franking machines are Mailmark-compatible. Older machines usually can't be upgraded and need replacing to gain Mailmark support.
Benefits of Mailmark
Cleaner, more professional franking impression on business mail.
Better postage rates on some Royal Mail services versus non-Mailmark franking.
More detailed reporting through your franking supplier's software.
How to switch to Mailmark
Request quotes from UK suppliers specifying Mailmark support. Suppliers will confirm compatible models for your mail volume.
Migration is typically a machine swap with a short setup period. Suppliers usually handle registration.
