Why do we put this in the notices

Hi all

I'm trying to understand the means of all the things that we send to them

But cant find out why we put below to debt angencys and solicitors I understand via royal mail.

. All communications are to be sent via Royal Mail exclusively and be
sent in a windowless envelope with a valid postage stamp affixed.


Any explanation please

Sorry I sound dumb

Thanks

All explained in the video,
Remember the first letter you get from them although it may not look like it
is an offer to contract. If you do not offer your terms to them ,they will have
a contract with you via your silent aquiescence.
Offer your own terms and conditions ,if they will not agree to them there cannot
be a contract between you and them. End of story.

more on mail fraud, NB this is NOT my research so research for yourself, from Telegram:

• Frivolous, unsigned, unsealed letters do not comply with the Companies Act 2006 Section 44 & 45.

• A PO Box is a non-contracting venue as it is not landbound to anything. This means they are in the act of committing fraud under the Fraud Act 2006, Sections 2 (1) False Representation and Section 11, obtaining services dishonestly.

• Franked mail is usually in direct violation of the Universal Postal Union Convention 1929, under Article 9 Violations, sections 2.1.2 prepayment impressions, 2.1.3 impressions of franking machines or printing presses and 2.2 concerning means of postal prepayment with the intention of obtaining illegitimate gain for oneself or for a third party.
