Can i post normal mail in franked maol only

In the UK, you can post normal mail (also known as "unfranked mail") in a franked mail bag or franked mail sack, but there are some limitations and considerations:

  1. Franking machine requirements: To use a franked mail bag or sack, you need a franking machine that is approved by Royal Mail. The machine must be able to print a franking mark (a postage stamp) on the mail items.
  2. Postage payment: You need to pay for the postage on the mail items before posting them in the franked mail bag or sack. You can do this by using your franking machine to print the postage stamps.
  3. Weight and size restrictions: Franked mail bags and sacks have weight and size restrictions. For example, Royal Mail's franked mail bags have a maximum weight of 25 kg and a maximum size of 600 mm x 400 mm x 400 mm.
  4. Mail type restrictions: Not all types of mail can be posted in a franked mail bag or sack. For example, you cannot post items that require a signature on delivery, such as recorded signed-for mail, in a franked mail bag or sack.
  5. Postage discounts: Franked mail bags and sacks can offer postage discounts for large volumes of mail. However, you need to meet certain volume requirements and follow Royal Mail's guidelines to qualify for these discounts.

If you're unsure about the requirements for posting normal mail in a franked mail bag or sack, you can contact Royal Mail or consult their website for more information.
