How to Audit Email Links Before Forwarding with Claude
Audit Email Links Before Forwarding with Claude and ToolRouter. Check all embedded links in an email for malicious content before clicking or sharing.
Tool
Use Claude with Phishing Email Checker to scan all links in an email and get a clear safe-to-forward verdict. Claude can explain why specific links were flagged — redirect chains, suspicious domains, known malware hosts — and suggest whether to sanitize the email before forwarding or skip it entirely.

Steps
Once connected (see setup above), use the Phishing Email Checker tool:
- Paste the email content and headers into the conversation.
- Ask Claude to run `check_email` via `phishing-email-checker` with a focus on embedded link safety.
- Ask Claude to list all links found, their verdicts, and an explanation for any that are flagged.
- Ask whether the email is safe to forward as-is, should be forwarded with flagged links removed, or should be dropped entirely.
Example Prompt
Try this with Claude using the Phishing Email Checker tool
Use phishing-email-checker to check all links in this email before I forward it to my team: [paste email content and headers]. List every link found, its verdict (clean or flagged), and an explanation for any flagged ones. Tell me whether it is safe to forward as-is or what I should do first.
Tips
- Check email newsletters from new or infrequent senders before forwarding — they are a common carrier for injected malicious links.
- Ask Claude to list the redirect destination of shortened links, not just the visible URL.
- If one link is flagged but the rest are clean, ask whether the email can be safely forwarded with that link removed.
