Two clients in one mailbox are not two subscribers.

Answer Two clients in one mailbox are not two subscribers. RFC 2180 discusses what happens when more than one client opens the same IMAP mailbox. The document is RFC 2180, titled IMAP4 Multi-Accessed Mailbox Practice. The practice is about a mailbox being opened from more than one client. It is not about a list growing. A person who reads mail in two places is still one person. A seller who counts the openings as subscribers is selling clients, not people.

The note that started this: RFC 2180, IMAP4 Multi-Accessed Mailbox Practice, RFC 2180.

Affiliate offers need people who can choose, not extra windows on one mailbox. When you look at solo ads for affiliate marketing, ask how a person is counted before you ask how the offer is written. A count of clients will make any list look busier than it is. Busy is not the same as opted in. You are renting one letter to someone else's list of people. You are not renting one letter per program that can open a mailbox.

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. The mailbox practice names none of them. Write the order so a client is not a subscriber. A seller who will not write that is keeping the right to invoice a second opening as a second person.

What does RFC 2180 discuss?

RFC 2180 discusses what happens when more than one client opens the same IMAP mailbox. The document is RFC 2180, titled IMAP4 Multi-Accessed Mailbox Practice.

What happens is a software question. Who counts as a subscriber is an order question. Do not let the first question answer the second. If a seller starts explaining mailbox practice, bring them back to the list name. You do not need a theory of mail clients to buy a solo. You need a refusal to pay for the same mailbox twice under two labels. The document is allowed to be interesting to people who write mail software. It is not allowed to become your audience.

Ask the seller to describe one reader who uses more than one client. Then ask whether that reader was counted once. If they hesitate, the count is a client count. Client counts are a fine thing inside a mail program and a bad thing on an invoice. The refund line should say that a count of clients, sold as a count of subscribers, is a reason to undo the order. Write it before the report arrives, because the report will look larger than the list.

• The order counts people, not mail clients.
• Two clients on one mailbox stay one subscriber.
• The list, the sending domain, and the refund line are named.
• A mailbox practice is not sold as the size of the list.

Are two clients two subscribers?

No. Two clients in one mailbox are not two subscribers. More than one client can open the same mailbox. The mailbox is still not a crowd.

The pitch will say the list is active because mail is opened from more than one place. Activity of software is not activity of a crowd. One reader can open the mailbox, leave, and open it again from another client. You have watched a habit, not a market. Do not price the habit. Price the letter to the list you named. If the seller cannot separate the habit from the list, you cannot know what you are buying, and the honest move is to keep the money.

Sellers who mean well still mix the words. Client, mailbox, subscriber, and list are not synonyms. Say subscriber only when you mean a person on the list. Say client only when you mean a program opening a mailbox. If you are the seller, fix the sentence before the buyer does. Buyers remember the mix as a trick even when it was sloppy language. Sloppy language on the size of a list is how refunds get emotional. Keep it boring and exact.

Does a second client prove a second 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 second client is not a second stranger, and it is not a second yes. Opt-in happens to a person, if it happens at all. Opening a mailbox again does not replay that choice. It does not prove the choice happened the first time. A document about multi-accessed mailboxes cannot stand in for the list owner's history with the reader. If that history is not available in plain words, you do not have proof. You have software.

When you buy solo ads, buy a letter to people, and make the order say so. Two clients in one mailbox are not two subscribers. Name the list, the sending domain, and the refund line. Leave mailbox practice with the programs that open mail. A second window is not a second customer, and it is not a reason to pay twice for the same reader.
