Scam Awareness Tool

Domain Safety Checker

Paste a domain, suspicious link, or sender email address to look for practical warning signs before entering card details, passwords, or account information.

Check a Domain

This checker looks for a small set of fast, useful signals: recent registration, basic mail security setup, HTTPS reachability, and suspicious naming patterns. It is designed to help ordinary users pause before trusting a site or sender.

Examples: example.com, https://example.com/pay, or [email protected].

Only the domain is checked. The tool does not read the full email or inspect the page content behind a checkout flow.

Important: A working padlock or HTTPS certificate does not prove that a site is trustworthy. Many scam sites still use HTTPS.

Privacy note: When you run a check, only the domain name is sent to our server, which looks up public registration and DNS records on your behalf. We do not store your searches or track which domains you check.

Warning Signs Worth Slowing Down For

These are common reasons a domain or sender deserves more caution, even if the page looks polished.

Brand-new domain registrations

Domains registered only days or weeks ago deserve extra skepticism, especially for stores, payment pages, and account-verification links.

Free mailbox senders

A merchant order confirmation or invoice from gmail.com or another free mailbox provider is not normal enough to ignore. Verify independently.

Payment or login wording in the hostname

Domains stuffed with words like secure, verify, billing, or login can be impersonation-style domains built to look convincing at a glance.

HTTPS is not the same as trust

Scam sites can still have a padlock. HTTPS only means the connection is encrypted. It does not prove who is behind the site.
