Email Authentication

Email Authentication is a critical process in foreign trade business used to verify the identity of customers or suppliers and confirm the authenticity of transaction instructions. Its core is to send/receive emails through officially registered email addresses or designated contact email addresses, and to verify email signatures, company domains, historical communication records, etc., in order to prevent phishing emails, impersonation fraud, or tampering with payment information. Use cases include: changing receiving accounts, confirming large orders, modifying contract terms, and other high-risk operations. Precautions: must use a company domain email rather than a free email; need secondary confirmation by phone; be alert to sudden links or attachments in emails; the difference from ordinary email confirmation is that email authentication emphasizes verification of the legitimacy of identity and authority, rather than mere information transmission. Foreign trade practitioners should establish an email authentication SOP to avoid payment losses caused by trusting emails blindly.
