You can frank almost any standard UK mail item – letters, large letters and parcels – with a Mailmark franking machine, and you’ll pay less than the equivalent stamp price. What you pay depends on the size and weight of the item, not what’s inside it.

Why frank instead of stamp?
Franked letters and large letters cost less than stamps, and Mailmark users get the lowest available rates. For volume senders, that difference adds up fast.
