Furthermore, the source - who Key refused to name - told him he was basing that claim on an "inference" he had taken from what Standard & Poor's had told the meeting.
Key insists his informant is well-known to him, someone who is trustworthy and reliable and who has previously passed on information which turned out to be correct.
Key obviously saved the email as useful material to throw back at Labour when the Opposition came after him in Parliament last week after the ratings downgrade the previous Friday. His attempt to catch Labour out has instead caught him out.
The whole episode might seem rather trivial in the grand scheme of things. However, the result of the election will be determined by two things - whether Labour can erode the vast stocks of kudos and credibility Key has built up with voters and whether Labour can persuade voters it would be a better manager of New Zealand's economy.
On both fronts, Labour is struggling badly. Key's own goals on both fronts will at least give some encouragement.
For Key, they serve as a timely pre-campaign reminder of the dangers of winging it without strong evidence to back up what you are saying.
