0–100, higher is better. How it is calculated

MailBing is a Chinese-based professional EDM (Email Direct Marketing) platform operated by Shenzhen Qianke Network Technology Co., Ltd. The platform offers a comprehensive suite of email marketing tools including bulk email list management, visual drag-and-drop email editing, high concurrency batch email sending with multi-IP rotation, and detailed email tracking and analytics. It targets businesses in cross-border trade and foreign trade sectors, emphasizing high delivery rates (up to 99.8%) and cost-effective pricing. The website is well-structured, mobile-optimized, and integrates modern web technologies such as Bootstrap and jQuery, with analytics from Baidu and Google Tag Manager. However, the domain WHOIS data is unavailable, which raises some trust concerns despite the professional presentation and ICP registration.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

MailBing positions itself as a leading domestic EDM platform with competitive advantages including high-precision email verification, multi-IP rotation for improved delivery, and built-in domain and email resources to enhance inbox placement. The business model is SaaS-based, offering subscription and pay-per-email pricing. The platform serves SMEs and enterprises in China focusing on cross-border e-commerce and marketing. The company maintains a broad partner ecosystem with related service providers in email APIs, site building, and marketing tools. Customer testimonials highlight satisfaction with subscription management, tracking, and email collection plugins. The company appears to be small-sized with a focus on technology and marketing sectors.

Security posture

The website enforces HTTPS and does not expose sensitive data in its HTML content. However, no explicit security headers were detected, and there is no visible cookie consent mechanism or published security/incident response policies. The absence of WHOIS data and domain registration details reduces trustworthiness. No known vulnerabilities or malware indicators were found in the content. The platform should improve security posture by implementing standard HTTP security headers, publishing privacy and incident response policies, and enhancing GDPR compliance. Overall, the security maturity is moderate but could be improved to meet enterprise standards.

Recommendations

  1. Implement and publish a comprehensive privacy and cookie consent policy with user consent mechanisms to improve compliance.
  2. Add standard HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish an incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  4. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to increase trust.
  5. Enhance GDPR compliance by including data retention policies and user data rights information.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, jQuery for DOM manipulation, and Feather Icons for UI elements. It integrates Baidu Analytics and Google Tag Manager for tracking user behavior. The site is mobile-optimized with good navigation and SEO meta tags. Performance is moderate with no major issues detected. No CMS was identified, suggesting a custom or lightweight framework. Hosting provider details are not disclosed. The site lacks some accessibility features and security headers, which are areas for improvement. Overall, the technical implementation supports the business goals effectively but could benefit from enhanced security and privacy features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
