HeaderCheck turns raw email authentication headers into clear SPF, DKIM, and DMARC verdicts, entirely on your iPhone or iPad. Paste headers, open a sample, or import an .eml (Pro). No account. No upload. Analysis never leaves this device. WHY IT MATTERS Phishing often fakes the From line. Authentication results in the headers show whether the sending domain actually passed SPF, DKIM, and DMARC. HeaderCheck makes those fields readable. HOW TO USE • Paste raw headers from “Show original” / “View source” • Or forward as attachment and open the .eml (Pro) • Read Pass / Fail / Softfail badges and heuristic flags • Copy a summary or export a PDF (Pro) FREE Paste analysis, badges, copy summary, and a rolling history of your latest analyses. PRO (one-time) PDF export, unlimited history, and .eml import / Share Sheet open. HeaderCheck reports what is in the headers you provide. It does not guarantee a message is safe or malicious, and it is not legal or forensic advice.
