Advanced Protection Features
Detect Relay and Alias Addresses
Identify addresses issued by Apple Hide My Email, DuckDuckGo Email Protection, Firefox Relay, SimpleLogin, addy.io, Proton Pass and 33mail — with an honest confidence score and the provider named.
Known Alias Domains
Match addresses against the domains each provider issues aliases from — privaterelay.appleid.com, duck.com, mozmail.com, simplelogin.co, addy.io and more. Every domain verified against live mail records, scored 99.
Custom Domains on Relay Infrastructure
Check where a domain's mail actually goes. A custom domain routed through SimpleLogin or addy.io is still an alias, and no domain list can know about it — this catches it, scored 90.
Confidence Scoring
Get an integer confidence score from 0-100 instead of binary detection, plus how the match was made. A score of 0 means nothing was detected, and a check we cannot complete is reported as skipped rather than guessed.
