  "statement": "The single permitted opt-out confirmation should reach the consumer within five minutes of the revocation.",
  "rationale": "A prompt confirmation is what buys the presumption that the revocation was honoured, and it is also the only signal the consumer gets that anything happened. Sent late it does the opposite work: a confirmation arriving the next day reads as another unwanted message from a programme they already left, and it is a common trigger for the complaint the confirmation was meant to prevent.",
