Mail goes to the research desk, not a ticket queue.
kyc0 is a one-person research desk, so both addresses below reach the person who wrote the page you are asking about. Pick the mailbox that matches your question.
Corrections and research questions
Write to research@kyc0.com. For the fastest correction, include the page URL, the disputed sentence, a primary source, and the date that source took effect. Material errors are corrected and the page’s review date is updated when the source set is rechecked — the full process is on the methodology page.
Vendors
Vendors can flag a factual error through the same address with a primary source attached. Fact checks are welcome; approval rights over wording, rankings, or conclusions are not part of the process. How commercial relationships are firewalled from research is documented on the disclosure page.
Privacy and data
Questions about how the site or calculator handles information go to privacy@kyc0.com. What the site does and does not collect is described in the privacy notes.
Before you write
- Do not email customer personal data, identity documents, or anything you are not permitted to share.
- kyc0 cannot provide legal advice or a compliance guarantee — for obligations, ask qualified counsel and the regulator for your sector.
- Disagreement with a stated fit judgment is read and considered, but on its own it does not establish a factual error.
