The size of the ask

Most signup boxes ask for nothing in particular, and that is exactly what they get.

Join our community. Be the first to know. Ten per cent off your first order, a field, a button. Nothing in there says what will arrive, or how often, or what it will never be used for. So the person types an address, takes the code, and has agreed to nothing they could describe a month later.

I have inherited both kinds of list, the one built on a code and the one built on a sentence, and they behave differently from the first send.

The code list grows all year and performs slightly worse every month. Nobody complains. They do the thing that is worse than complaining, which is nothing at all. In a market where half the phones have a folder of codes on them, the code was the product and the address was the price the customer paid for it.

The other ask says the whole thing out loud. One email a week, on Tuesday. It is about how the thing is made. There is no offer in it and you can leave from any line. That collects fewer people. Sometimes a tenth as many.

But the email that arrives is the email that was promised, which is the only condition under which a send is worth writing. And the specific ask does a second job nobody credits it for. It makes the sender decide. You cannot promise Tuesday and then not have a Tuesday. You cannot promise no offer and then need the offer in week three.

The vague box survives because it is measured on the way in, where it looks generous, and never on the way out.

A promise nobody can repeat back to you was never made.
