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

WarmupInbox operates a professional SaaS platform focused on improving email deliverability through an email warmup tool and related services. The company targets marketers, sales professionals, lead generation experts, and recruiters, offering a subscription-based model with competitive pricing and a 7-day free trial. The website demonstrates strong market positioning with multiple trust signals including customer testimonials, case studies, and recognized review badges. Technically, the site is built on WordPress with modern plugins and integrations such as Elementor, Yoast SEO, and various analytics and marketing tools, ensuring good SEO, mobile optimization, and user experience. Security posture is solid with HTTPS enforced and cookie consent implemented, though there is room for improvement in security headers and public security policies. The absence of WHOIS data suggests privacy protection or recent registration, which slightly impacts trust but is common in privacy-conscious businesses. Overall, the site is professional, trustworthy, and well-optimized for its business purpose.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

WarmupInbox's business model centers on providing email warmup services to improve cold email campaign effectiveness. Their competitive advantage lies in real-user inbox networks, automation, and fair pricing. The company maintains a strong partnership ecosystem with integrations for major email providers and offers free tools to attract and retain users. The presence of multiple case studies and testimonials indicates a focus on customer success and credibility. Marketing efforts leverage extensive tracking and retargeting technologies to optimize conversions. The lack of direct contact information on the homepage suggests a focus on self-service and account-based interactions. Overall, WarmupInbox appears to be a small but mature player in the email deliverability technology sector with a clear growth trajectory.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms, reflecting awareness of privacy and security best practices. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, and no public security policy or incident response contacts are published. The use of multiple third-party scripts increases the attack surface and necessitates regular security audits. The absence of a vulnerability disclosure policy or security.txt file limits transparency in security incident handling. No vulnerabilities or exposed sensitive data were observed in the HTML content. Overall, the security posture is moderate with opportunities for enhancement in transparency and technical controls.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to harden the website against common attacks.
  3. Create and maintain a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and plugins to mitigate risks from vulnerabilities.
  5. Consider providing clearer contact information for business and security inquiries to enhance credibility.

Technical notes

Notes

The website is built on a WordPress CMS platform using the Elementor page builder and Yoast SEO plugin, ensuring strong SEO and content management capabilities. It integrates multiple marketing and analytics tools including Google Tag Manager, Microsoft Clarity, Intercom, Visual Website Optimizer, and User.com, enabling extensive user tracking and conversion optimization. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by the number of third-party scripts loaded. Hosting provider details are not explicitly identified. The technical stack is modern and well-suited for the business model but requires ongoing maintenance to manage third-party dependencies and security risks.
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.
