Prevent Fraudulent Signups
Score email based on disposable, free provider, name mismatch, and domain age to prevent fake registrations.
Run the tool
This tool performs a live lookup (DNS, WHOIS, or a page fetch) that a browser cannot do on its own, so the value you enter is sent to our server for that check. It is not stored. If the lookup is unavailable, the tool falls back to its offline formula and tells you.
Under the hood
How this tool works
No black box. This is the exact logic the tool runs on every input you give it.
Formula
Risk = (40 × Disposable) + (25 × Role) + (20 × NoMX) + (15 × Syntax) → 0–100
- 1
Validate every number you enter and guard against divide-by-zero.

Apply the formula above with full precision, rounding only at display time.
- 3
Derive the secondary metrics that put the headline number in context.
- 4
Benchmark the result against the typical range for this metric, so you know whether it is good.
