Link check: spot fake links in e-mails

Free link check: test an e-mail’s links and attachments for phishing – fake domains, hidden targets, dangerous attachments. Runs in the browser, no storage.

Where do I find the source?
Outlook (klassisch)
Open the message with a double click, right-click in the text → “View source” and copy everything – the HTML is enough for the link check. Saved .msg files are not supported.
Neues Outlook
Open the message → … → View → View message source → copy all.
Outlook im Web / Microsoft 365
Open the message → … → View → View message source → select all and copy.
Gmail
Open the message → ⋮ → Show original → Copy to clipboard.
Apple Mail
View → Message → Raw source (⌥⌘U) → copy all.
Thunderbird
Open the message → Ctrl+U (source) → copy all, or save the message as .eml.

No data is stored or transmitted. The analysis runs entirely in the browser – the e-mail never leaves the device and the links are not opened.

Background

How to recognise phishing links.

Phishing e-mails usually show a familiar name but lead to a foreign site: a typo in the domain, a brand name in someone else’s address, a link shortener or letters from other alphabets. The link check reveals where every link really leads and also checks attachments – without opening a single link.
