Is This Domain Safe? Scan Its Reputation in Seconds
Wondering whether a domain is safe, legitimate, or worth buying? Enter it above to run a four-point reputation scan covering HTTPS status, DNS configuration, email authentication, and domain age. The checker evaluates the same signals that search engines, email providers, and security systems use to decide whether a domain is trustworthy — and gives you a clear trust score in seconds, with no signup.
If you want the full picture on a domain, this tool is part of an all-in-one domain analyzer that also checks age, availability, DNS, SSL, and traffic.
What We Check
HTTPS status verifies that the domain has a valid SSL certificate and responds to encrypted connections. Domains without HTTPS are flagged “Not Secure” by modern browsers and can be penalized in search rankings. For a deeper certificate analysis, use our SSL Certificate Checker.
DNS configuration examines whether the domain has properly configured A records (pointing to a web server) and MX records (handling email). A domain with A records but no MX records may not be set up for email — fine for a simple site, concerning for a business domain. Our DNS Lookup Tool shows the full record set if you need more details.
Email authentication checks for SPF (Sender Policy Framework) and DMARC records. These DNS-based protocols stop unauthorized parties from sending email that appears to come from the domain. Domains with both SPF and DMARC are far more resistant to spoofing and phishing.
Domain age assessment evaluates registration history using RDAP data. Older domains generally carry more trust. A domain one year old or younger fails the age check, and one between one and five years old gets a warning — not because new domains are untrustworthy, but because they haven’t built a track record yet. For the full timeline, visit our Domain Age Checker.
How each check is scored
| Check | Pass | Warn | Fail |
|---|---|---|---|
| HTTPS | Valid HTTPS connection | — | No valid HTTPS |
| DNS configuration | A and MX records found | A records, no MX | No A records, or the lookup failed |
| Email authentication | SPF and DMARC both found | Only one of the two | Neither |
| Domain age | Older than 5 years | 1 to 5 years | 1 year or younger |
Age comes from the registry’s RDAP record, DNS and SPF/DMARC from Cloudflare DNS-over-HTTPS, and the HTTPS result from a direct request to the domain. The tab shows how many of the four checks passed, for example 3/4; the JSON endpoint reports the worst single result as the grade.
How to Tell If a Domain Is Legitimate or a Scam
A reputation score is the fastest signal, but a few manual checks help you judge an unfamiliar domain with confidence:
- Check the domain age. Scam and phishing domains are often days or weeks old. Our reputation check fails any domain one year old or younger, and warns on one to five years.
- Confirm valid HTTPS. A missing or broken certificate on a site that handles money or logins is a red flag. A valid certificate proves nothing on its own, because anyone can get one free in minutes.
- Cross-check the email setup. A “business” whose domain has no SPF or DMARC record cannot send authenticated email.
- Look for lookalike spellings. Extra letters, swapped characters and a different TLD on a brand you know are the classic pattern.
- Check blacklists and security vendors separately. This checker does not query blacklists or malware databases. Use VirusTotal or Google Safe Browsing for that, and see our blacklist guide.
No single signal is conclusive, but a domain that fails several at once is one to avoid.
How to Evaluate If a Domain Name Is Good
If you’re buying a domain rather than just checking it, “trustworthy” is only half the question — you also want a domain with real value. A good domain typically combines a clean reputation with a few quality signals:
- History and reputation: no spam, malware, or blacklist baggage from previous owners.
- Age: an established registration date adds inherent trust. Check it with the Domain Age Checker, and read our walkthrough on how to check domain age before buying.
- Existing traffic and authority: a domain that already attracts visitors and links is worth more. Estimate it with the Domain Traffic Checker.
- Brandability and TLD: short, memorable, and on a credible extension (.com still leads for trust).
- Availability of variants: if you’re registering fresh, confirm the name and its key TLDs are free with the Domain Name Availability Checker.
For the full evaluation framework, see our guide on how to evaluate a domain before buying.
What Your Domain Reputation Score Means
The trust score combines the four checks into a single rating so you can judge a domain at a glance. A high score means the domain passes the security and configuration standards that search engines, mailbox providers, and browsers expect: valid HTTPS, sensible DNS, email authentication in place, and an established registration date.
A lower score points to specific gaps — a missing certificate, no SPF/DMARC, or a brand-new registration. New domains often score lower simply because they haven’t built history yet; that’s expected and resolves with time and proper setup. The scan covers configuration and history signals only — it does not query spam or malware blacklists, so pair it with our blacklist guide for that check. The score is a starting point for due diligence, not a verdict — use it alongside the manual checks above.
Domain Reputation vs Email Sender Reputation
“Domain reputation” means three different things. Threat reputation is whether security lists such as Spamhaus DBL or Google Safe Browsing flag the domain for spam, malware or phishing. Sending reputation is how Gmail and Outlook rate the mail you send, built from bounces, spam complaints and engagement; only the mailbox providers see it, through Google Postmaster Tools and Microsoft SNDS. Google asks bulk senders to keep spam complaints below 0.30%, and recommends staying under 0.10%. Configuration reputation is what this checker scores: HTTPS, DNS, SPF/DMARC and age. Good configuration is the precondition for the other two, not a substitute: a well-configured domain can still be blocklisted or land in spam.
When to Use a Reputation Check
Before buying a domain: expired and aftermarket domains come with history. Running a reputation check before purchase is basic due diligence.
Monitoring your own domains: reputation isn’t static. Certificates expire, DNS drifts, and authentication records break after hosting changes. Regular checks catch these before they hit email deliverability or rankings.
Evaluating partners and links: before linking to, partnering with, or accepting a guest post from an unfamiliar domain, a quick check reveals whether it meets basic security and configuration standards.
Improving a Low Reputation Score
If a domain fails checks, the fixes are usually quick. Install an SSL certificate — Let’s Encrypt offers them free. Add SPF and DMARC records to your DNS. Make sure nameservers are configured correctly and A records point to an active server. Most of these can be completed in under an hour, and they immediately improve how search engines, email providers, and security tools evaluate the domain.
Monitor this domain with your AI assistant
You don’t need an account here. ChatGPT, Claude and most assistants can run a recurring task for you. Copy the prompt below into your assistant, replace example.com with your domain, and ask it to run weekly.
Every Monday, fetch https://domainanalyzer.com/wp-json/dat/v1/domain/example.com and compare with last week: domain expiry, SSL certificate expiry, SPF and DMARC, nameservers, MX records, HTTPS status and reputation grade. Tell me only what changed, and warn me if the domain or the certificate expires in under 30 days.
The endpoint is free, needs no key, returns plain JSON with a one-line summary, and is the same data this page shows. It does not check blacklists or DKIM. Details for developers and agents: domainanalyzer.com/llms.txt

How do I check if a domain is legitimate?
Run the domain through a reputation checker to confirm it has valid HTTPS, sensible DNS, email authentication, and an established registration date. Then verify it isn’t on any blacklists and isn’t a lookalike of a known brand. A domain that fails several of these at once is best avoided.
How can I tell if a domain is safe?
A safe domain has a valid SSL certificate (HTTPS), properly configured DNS, email authentication, some registration age — and no blacklist history. Our free reputation checker scores the HTTPS, DNS, email-authentication, and age signals in one scan; for blacklist history, follow our step-by-step blacklist guide.
What is a domain reputation score?
It’s a single trust rating that combines key signals — HTTPS status, DNS configuration, email authentication (SPF/DMARC), and domain age — into an at-a-glance measure of how trustworthy a domain appears to search engines, email providers, and security systems.
How do I evaluate whether a domain name is good?
Beyond a clean reputation, a good domain has an established age, existing traffic or authority, a credible TLD (.com still leads), and a short, brandable name. Check age and traffic with our dedicated tools, and confirm there’s no negative history before buying.
Why does a new domain get a low reputation score?
New domains haven’t built a track record yet, so they’re flagged as a precaution — not because they’re inherently untrustworthy. The score improves over time as the domain establishes history and as you complete proper SSL and email-authentication setup.
Is the domain reputation checker free?
Yes — it’s completely free with no signup required. Enter any domain and get an instant four-point reputation scan and trust score.
What is a domain reputation check?
A domain reputation check tests a domain against a fixed set of trust signals and returns one score. This one runs four: HTTPS validity, DNS configuration, email authentication (SPF and DMARC), and registration age. Each returns pass, warn, or fail, and the result shows how many of the four passed.
How do I run a domain reputation check?
Enter the domain above and click Analyze. The check takes a few seconds and needs no signup. You get the four individual results plus the combined score, and any failing check links through to the tool that diagnoses it.
How often should I run a domain reputation check?
Before you trust a domain you have not dealt with before, and after any change to your own DNS, SSL, or email records. Reputation signals move whenever the underlying configuration moves — a score from six months ago tells you nothing about today.
Can I use this to check if a domain is a scam?
Not by itself. This tool scores configuration hygiene — HTTPS, DNS, email authentication (SPF and DMARC), and registration age — which is what hastily assembled domains usually get wrong. A scam site can still pass all four, because a valid certificate and tidy DNS cost nothing and take minutes to set up. Read a failing score as a reason to stop, and a passing score as one input among several: check the domain against blacklists too, and watch for lookalike spellings of a brand you already know.
My domain passes this check, but my email still goes to spam. Why?
This check confirms that SPF and DMARC exist; it cannot see how Gmail or Outlook rate your sending. Open the message in Gmail and read the stated reason: “isn’t authenticated” points to SPF, DKIM or DMARC alignment, while “similar to messages identified as spam” points to content, complaints or a cold new domain. For the second, check Google Postmaster Tools, clean bounces from your list and raise volume slowly.
