The amount you pay for sending a UK mail item by Royal Mail depends simply on the size and weight of the item you intend to send. You can frank a wide array of items with a Mailmark franking machine, all of which will save you money over stamps.
Below is a table from The Royal Mail’s website for your reference of the mail items you can send with a franking machine. Use the table to work out which format your item falls into.
