Affiliate disclosure. The partner link in the masthead and in the band beside the copy on this page is a sponsored link to a partner operator, and this site may be paid if you open an account through it, at no extra cost to you. It carries rel="sponsored noopener" and opens in a new tab. A desk about the messages an operator sends has no business leaving its own material unsaid, so its interest is stated here rather than left for a footer: one link funds the site, and no operator, platform, mail provider or product is named, rated or recommended anywhere on it.

Six beliefs, checked against the samples

Six beliefs about operator messages, checked

Each belief below is stated the way a reader would put it, then checked against the samples rather than against an opinion. Four are false, one is partly true, and one holds.

Direct answer

Four of the six beliefs are false and one is partly true. An opt-out stops 12 of 50 messages, not all of them; a sent message is evidenced as arriving 48 times in 50; a receipt is not a thing a reader can refuse; a free channel is not equivalent to a paid one; operators keep a template reference rather than the wording; and silence is not evidence that nothing happened.

Six beliefs, each checked against a sample

Each belief below is stated the way a reader would put it, and the check beside it names the sample it rests on rather than an opinion about operators.

false

An opt-out stops everything

It stops marketing: 12 of 50 messages on the samples, 24.0%. The other 38 continue, because four of the five kinds are not marketing and the terms permit them. No wording at the foot of a message changes that.

false

If it was sent, it arrived

Sent and arrived are two counts: 50 and 48. The two that differ were posted, and the paper channel carries no arrival evidence at all. Reading is a third count again, at 21.

false

I can refuse to receive receipts

A receipt records an event that already happened, so refusing it removes the record rather than the event. The account usually cannot be kept without them, and the samples send 30 of 50.

partly

A free channel is just as good

It is faster and cheaper, and 13 of 50 messages use one. What it is not is durable or provable: in-app and push have no paper copy and no post record, so a notice moved onto them keeps its window but loses its evidence.

false

The operator keeps the wording it sent

Nine of twelve fields are kept, and the rendered text is not one of them; a template reference is kept instead. The three dropped fields are the ones a reader quotes.

holds

Silence does not mean nothing happened

A log proves sends, not absences. With 2 of 50 notices in a month and windows as short as 2 days, a change can be made and take effect without a message the reader can point to.

the six beliefs against the samples belief 1 opt-out stops everything -> 12 of 50 = 24.0% belief 2 sent means arrived -> 48 of 50 = 96.0% belief 3 receipts can be refused -> 30 of 50 = 60.0% are receipts belief 4 free equals paid -> 13 of 50 = 26.0% use a free channel belief 5 the wording is kept -> 3 of 12 fields dropped = 25.0% belief 6 silence means nothing -> 2 of 50 = 4.0% are notices one belief of six survives contact with the arithmetic.
  • Check the kind of message before reaching for the switch at the foot of it.
  • Separate sent, arrived and read whenever a message is said to have been delivered.
  • Keep the messages yourself if the wording matters, because the log holds a reference, not the text.
  • Prefer a channel that leaves a copy for anything with a date attached to it.
  • Treat an absence as a question about the window, not as proof that nothing was decided.
