A well-placed open loop — a question raised but not immediately answered — is one of the most reliable ways to keep a reader moving through a long letter.
Raise a Specific Question Early
A curiosity gap works best when it's concrete and relevant, not vague or disconnected from the reader's actual interest.
Delay the Payoff Without Losing the Reader's Patience
The gap between raising the question and answering it should feel purposeful, not like the letter is stalling.
Close Every Loop You Open
A reader who notices a raised question never gets answered feels manipulated, which undermines trust in the rest of the letter.
