Your mail setup has problems.
r3webdesign.de fails 1 mail check: Subdomain policy (sp=none) is weaker than domain policy (p=reject). This is the kind of misconfiguration that sends your mail to spam.
Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
Cross-Origin-Embedder-Policy header is missing
COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.
Cross-Origin-Opener-Policy header is missing
COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
HSTS is enabled but missing includeSubDomains
Without includeSubDomains, a forgotten dev subdomain over HTTP can set malicious cookies that ride to the apex.
No Permissions-Policy header
Permissions-Policy locks down browser APIs you don't use, shrinking the attack surface.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€428 investment → €709/month returns + EUR 500,000 risk avoided
Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
2 barrier(s) likely increasing bounce by ~3%.
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web.
Open Graph is a protocol that is used to integrate any web page into the social graph.
Priority Hints exposes a mechanism for developers to signal a relative priority for browsers to consider when fetching resources.
