An object id in a mailbox is not a subscriber id.

Answer An object id in a mailbox is not a subscriber id. RFC 8474 describes IMAP object identifiers. An id for a message or a mailbox object is not a customer id. The document is RFC 8474, titled IMAP Extension for Object Identifiers. 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.

The note that started this: RFC 8474, IMAP Extension for Object Identifiers, RFC 8474.

A rented send is one letter to someone else's list. An id on a message or a mailbox object is not that letter, and it is not permission. A seller who pastes an id and calls it a customer is handing you mail software. A buyer who needs a subscriber is asking who joined. The id cannot answer. Put the list name on the order in words a person can read.

When you compare best solo ad vendors, ask what an id on the pitch actually identifies. If it identifies a message or a mailbox object, it is not a customer id. It will not tell you the list, the sending domain, or the refund line. Ask for those in writing. A vendor who answers with the document title has described a protocol, not a send.

What does RFC 8474 describe?

RFC 8474 describes IMAP object identifiers. An id for a message or a mailbox object is not a customer id. The document is RFC 8474, titled IMAP Extension for Object Identifiers. The id points at an object in the mailbox, not at a person who asked for the offer.

Mail software needs a way to point at a message or a mailbox object. That pointer is an id. It helps the mailbox keep track of its own objects. It does not roll those objects up into customers. If a seller exports ids and calls the export the list, ask for a name you can write on the order. An id you cannot tie to that name is not the file you think you are buying.

You can store the id and still not know who opted in. The rented letter goes to the named list, from the named sending domain, under the refund line you accepted. The object id does not choose the list and does not prove a stranger asked. If the only artifact on the call is a string of identifiers, stop and ask for the creative and the list name. A mailbox object is not a lead.

• The order names the list, not an object id.
• The sending domain is written before you pay.
• The refund line covers a list or domain that is not what you named.
• An id for a message or a mailbox object is not called a customer.

Can a mailbox object id prove someone opted 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. An object id in a mailbox is not a subscriber id.

Opt-in is a person asking to be mailed. An object id is a handle for something stored. A report that leans on ids is a report about mailbox objects. Do not pay it as a report about people. A seller who says the ids prove quality is pointing at software. Quality you can judge is a named list that was supposed to want this kind of letter. The id does not show that want.

Your offer records a request for the page, or it does not. It does not record a mailbox object id, and it should not be asked to. If the invoice follows those ids, you are paying for mailbox bookkeeping. Ask which event the invoice follows. If the seller cannot separate the id from the person, do not send the money. Labeling ids as subscribers trains the buyer to come back when the offer does not recognize them.

What should the order name instead of an object id?

A buyer still has to name the list, the sending domain, and the refund line on the order. An id for a message or a mailbox object does not stand in for any of those names.

Say the list in words. Say the domain that sends. Say what the refund line says if either is wrong. That is the order. The document can be attached as a note if someone is confused about identifiers. It cannot be the order. A seller who will only discuss object ids is not describing a solo. A buyer who pays on an id is buying a pointer.

Hold a page of safe solo ads sellers to the same test. A careful seller can say the list, the sending domain, and the refund line without reaching for an object id. If the pitch needs the id to sound precise, the precision belongs to mail software, not to the people on the file. Leave the id in the mailbox. Buy the letter, or do not.
