What to include in your message

A few details up front help us answer faster — especially when the question concerns a specific article or claim. If you can, mention:

Corrections & updates

We take accuracy seriously. If you spot a mistake — a wrong figure, an out-of-date reference, a misattributed quote — please flag it. Substantive corrections are noted at the bottom of the affected article with the date the change was made, in line with our standing editorial practice.

Send corrections to contact@testml.org with the subject line “Correction” and a link to the page in question.

Privacy of your message

Anything you send us is read by editorial staff only and is not shared with third parties. We don’t pass reader email addresses to advertisers, mailing-list vendors, or analytics tools. For the full picture, see our Privacy Policy.

A note on response times: we aim to reply to every genuine reader email within two working days. During holiday periods replies may take a little longer — thank you for your patience.
