Mailmark
A discounted service which involves the addition of a Mailmark barcode, making each item uniquely identifiable and machine readable. Can be applied to sorted or unsorted mail.

Optical Character Recognition (OCR)
Font types which can be read by Royal Mail sorting machines, automating the process which means discounts on pricing. Can be applied to sorted or unsorted mail.

Hight Sort (1400/70)
Are certain mailing items that fail to meet the machine specifications set and these are called High Sort e.g. polythene wrapped, or you choose to not use an OCR font – for instance using a type font that looks like it is hand written because it can increase response rates.

A discounted service aimed at promotional mail pieces with a largely uniform message with the sole aim of promoting goods or services, or support of a charitable cause. Can be applied to sorted or unsorted mail.

Business Mail
Basic sorted or unsorted personalised correspondence which does not qualify for any discounts.

Sustainable
A discounted service aimed at promotional mail pieces with a largely uniform message with the sole aim of promoting goods or services, or support of a charitable cause.
