Gmx.de (Domain) Investigation Report
Generated on May 24, 2026
Β Why we think so?Β
β gmx.de looks like a long-running, high-traffic German email service, not a scam. It has millions of monthly visits, valid DNS and SSL, and no Safe Browsing or crypto-blacklist hits. The main caution is reputational: GMX-branded email is frequently spoofed in phishing, so users should verify sender addresses and links carefully.
Risk Insights
Legitimate mail platform, not a scam site
- Traffic, DNS, and SSL all fit a real email provider.
- No curated blacklist or Safe Browsing hit was found.
- GMX branding is real and established, backed by trademark records.
Phishing risk comes from imitation
- Attackers often forge GMX-looking emails to steal logins.
- Verify the sender domain before clicking anything.
- Use the browser address bar for sign-in and account checks.
Category Scores
Red Flags & Warnings
- GMX addresses are widely abused in spam and phishing campaigns, so lookalike emails are a real risk even if the domain itself is legitimate.
Detailed Checks & Insights
0-100 Scale
Domain age / longevity
Score: 50
Domain age / longevity
"This lowers certainty a bit, but other signals still support legitimacy."
Reason: No WHOIS creation date was available in the evidence set, so domain age could not be verified directly.
Registrar / WHOIS consistency
Score: 55
Registrar / WHOIS consistency
"Because this is a common limitation for well-known domains, it is not a strong negative on its own."
Reason: The WHOIS record is incomplete, with registrar and registrant fields missing, so ownership cannot be checked in the usual way.
Traffic scale and pattern
Score: 93
Traffic scale and pattern
"The audience is real and concentrated in Germany, which fits the claimed service."
Reason: Similarweb shows meaningful, stable usage with roughly 2.2M monthly visits, a strong Germany share, and long-standing email-provider traffic patterns.
Technical infrastructure
Score: 90
Technical infrastructure
"The presence of standard mail and security infrastructure is consistent with a legitimate email platform."
Reason: The domain resolves cleanly, uses MX records for mail delivery, and presents a valid wildcard SSL certificate.
Brand / trademark support
Score: 85
Brand / trademark support
"The trademark history is older and mixed, but it still aligns with an established service name."
Reason: USPTO records show multiple GMX marks, which supports the existence of a real brand behind the domain.
Blacklist / phishing reputation
Score: 95
Blacklist / phishing reputation
"This is one of the strongest positive signals in the evidence set."
Reason: No Google Safe Browsing issue and no crypto scam blacklist hit were found.
Public reputation / complaints
Score: 78
Public reputation / complaints
"There are phishing complaints tied to forged GMX mail, but those are abuse of the brand rather than proof the domain itself is malicious."
Reason: Public discussion focuses on normal email-provider complaints, ads, and app usability, not on the domain being a scam.
Physical/business presence
Score: 45
Physical/business presence
"This is not unusual for a large online-only service, but it limits location verification."
Reason: No Google Places listing or confirmed physical location was returned for gmx.de in this evidence set.
