About this tool
What the privacy checker looks for
Some addresses leak role prefixes (admin, support), plus-tag aliases, or known disposable domains. This tool runs local heuristics so you can decide whether an address is safe as a long-lived identity or whether it over-shares when used in public forms.
What it does not do
No third-party blocklist API calls, no upload of your email, and no identity resolution. Results are advisory; whether a site accepts the address depends on their policy.
Recommended workflow
- Create a disposable inbox on Freetempmail for low-risk signups.
- Run your own addresses through this checker before reusing them.
- Keep long-lived accounts on a permanent mailbox with a unique password.
