A saved page bundle is not the live offer.

Answer A saved page bundle is not the live offer. RFC 2557 describes MHTML, a way to pack a web page and its pieces into a MIME message. The document is RFC 2557, titled MIME Encapsulation of Aggregate Documents, such as HTML (MHTML). The bundle is a packed copy. The live offer is whatever the page says when someone acts on it later. Those are not the same object. A seller who shows you the live page and sends the bundle has shown you one thing and mailed another.

Cream stationery and a teal accent on a dark navy desk — A packed page is not the offer that is live.

The note that started this: RFC 2557, MIME Encapsulation of Aggregate Documents, such as HTML (MHTML), RFC 2557.

Vendors get this wrong in both directions. Some demo a live page that no longer matches the pack. Some mail a pack and call it the page you approved yesterday. The best solo ad vendors can tell you which object the reader is supposed to act on. If they cannot, you do not know what you are buying. A rented letter is one letter to someone else's list. A saved bundle is not that letter by itself, and it is not permission.

That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in. A buyer still has to name the list, the sending domain, and the refund line on the order. MHTML names none of them. Add a sentence to the order: if the saved bundle and the live offer disagree, the refund line applies. You are not asking the seller to become a historian of pages. You are asking them to name the object you approved.

What is MHTML?

RFC 2557 describes MHTML, a way to pack a web page and its pieces into a MIME message. The document is RFC 2557, titled MIME Encapsulation of Aggregate Documents, such as HTML (MHTML).

Packing is a way to carry a page and its pieces inside mail. Carrying is not publishing, and it is not a promise that the live page still says the same thing. Buyers who approve a bundle should approve it as a bundle, with eyes open that the live offer can be a different object. Sellers who approve a live page in a call and then pack an older copy have switched objects without saying so. The switch is the whole dispute. Write it down before it happens.

You do not need the packing method to have the dispute. You need the words of the offer. Read them in the message that will go out. Read them on the live page if the letter sends people there. If you cannot match the two readings, do not pay for a story that they match. A specification for packing pages will not reconcile them. It only explains that a packed form exists. Existence is not agreement.

The order says whether the reader acts on a bundle or a live page.
The seller shows the object you are asked to approve.
The list, the sending domain, and the refund line are named.
A disagreement between bundle and live offer uses the refund line.

Is a saved page bundle the live offer?

No. A saved page bundle is not the live offer. The bundle is a packed copy inside a message. The live offer is a different object, and the two can disagree.

Disagree is the buyer problem. The promise in the letter and the next step in the letter can be stale relative to the page, or the page can have moved on while the letter stayed honest. You do not fix that by admiring the pack. You fix it by deciding which words are the offer and putting those words where the reader will see them. If the only copy of the offer is inside a saved bundle, say that in the order. If the live page is the offer, the letter has to send the reader there without pretending the pack is the page.

Does a packed page prove opt-in?

No. That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in.

A packed page does not remember who asked for mail. It can look complete and still be unwanted. Completeness is a property of the bundle, not of the list. Do not let a neat pack stand in for a signup, a rank, or a price. Ask for the list and the sending domain. Ask what the refund line says when the bundle and the live offer are not the same thing. A seller who answers with the name of the packing method has changed the subject.

Keep the offer in words you can read on the day you pay. That is also how you read safe solo ads sellers: by what they show you, not by the format they can name. A saved page bundle is not the live offer. Name the list, the sending domain, and the refund line. A packed copy is not the audience, and it is not a yes.
