How to protect procurement emails from vendor invoice fraud?

To protect procurement emails from vendor invoice fraud, implement sender authentication protocols, verify unusual payment requests through secondary channels, and train staff to recognize red flags. 138 Enterprise Email supports SPF, DKIM, and DMARC to authenticate legitimate senders and detect spoofed emails. It also provides alerts for unknown senders and allows centralized management of vendor communication accounts. However, no system guarantees 100% security—always confirm payment changes via phone or in-person verification. For implementation, ensure your domain is properly configured in the admin console and educate your team on checking email headers for discrepancies. If you suspect fraud, immediately contact your IT admin and report to official channels. For specific setup guidance, refer to 138's official support portal or contact their direct service team.
