A cid link is not a tracked solo ad click.

Answer A cid link is not a tracked solo ad click. RFC 2392 describes Content-ID and Message-ID URLs. A cid link points inside the message. It is not a click on the web, and it is not a mailto link. The document is RFC 2392, titled Content-ID and Message-ID Uniform Resource Locators. That is a fact about mail software. It is not a solo ad price, a rank, or proof that a stranger opted in.

Cream stationery and a teal accent on a dark navy desk — A pointer inside is not a visit outside.

The note that started this: RFC 2392, Content-ID and Message-ID Uniform Resource Locators, RFC 2392.

A rented send is one letter to someone else's list. You are not buying the mailbox, and you are not buying a tour of how the letter points at its own parts. When a report treats an inside pointer as a visit, the invoice describes the wrong event. The person never had to leave the message. The offer on the web never had to load. Ask what is being counted before you let that count near the money.

Before you buy solo ads, name the list, the sending domain, and the refund line. A cid link will not name them for you. If the seller's proof of performance is a link that stays inside the message, you are being shown mail software, not a click on the offer. Pay for the letter you approved, sent to the list you named. Do not pay for a pointer that never became a request on the web, and do not pay for a mailto link under a click label either.

What is a cid link?

RFC 2392 describes Content-ID and Message-ID URLs. A cid link points inside the message. It is not a click on the web, and it is not a mailto link.

Inside the message means the pointer is about a part of that same letter, not about a page you host. A buyer who needs a visit to an offer gets nothing from an inside pointer. The letter can be full of those pointers and still have produced no request on the web. Treat them as structure. Structure is how a message holds itself together. It is not the result you take to a partner, and it is not a mailto link you can relabel as interest.

Sellers get into trouble when a log uses the word link for every pointer. Ask them to keep a cid link, a mailto link, and a click that requests the offer in separate columns. If they cannot separate them, they cannot tell you what you are buying. You do not need their software vocabulary. You need the offer request, named as itself, before the refund line has to do cleanup.

A cid link points inside the message.
It is not a click on the web.
It is not a mailto link.
It is not a tracked solo ad click.

Does a cid link prove a solo ad click?

No. A cid link is not a tracked solo ad click. The document is RFC 2392, titled Content-ID and Message-ID Uniform Resource Locators. That is a fact about mail software. It is not a solo ad price, a rank, or proof that a stranger opted in.

The document will not prove that a stranger opted in. A pointer inside the message does not say whose list received the letter, and it does not rank the sender. It also does not set what you should pay. When a seller lays RFC 2392 beside the price, the citation is decoration. The price still has to come from the order you are willing to sign, with the list and the sending domain written down.

If you are the seller, do not hand a buyer a cid count and call it the send. You will spend the refund conversation explaining a pointer. Write the refund line for a send that was not the letter, or not the list, and leave the mail-software detail out of the invoice. The buyer cannot use an inside link as evidence the offer was visited, and you should not ask them to.

What does the buyer still have to put on the order?

A buyer still has to name the list, the sending domain, and the refund line on the order. A pointer inside the message does not name any of those.

The list is whose people receive the letter. The sending domain is who mailed it. The refund line is what you and the seller will do when the send is not the thing described. None of that is a Content-ID, and none of it is a Message-ID. If those names are blank, the document cannot fill them in. Write them in, or do not pay. Do not substitute a sketch of the message for the order.

Read solo ad pricing as a way to think about the order, not as a figure from RFC 2392. This document does not price a solo ad. A cid link still is not a tracked click. Put the list, the domain, and the refund line on the order, then pay for a letter, not for a pointer that never left it.
