DuckDuckGo Email Protection vs EmailAlias.io

DuckDuckGo Email Protection is a free forwarding service that removes multiple types of hidden email trackers while working with an existing email account. Users select a personal @duck.com address, and messages sent there are checked against DuckDuckGo’s block list before forwarding to a regular inbox. The service can also create distinct private Duck Addresses that can be turned off individually if they attract spam or other unwanted mail. DuckDuckGo browsers and extensions can recognize email fields and fill in either the personal or a generated private address. Forwarded messages can arrive in accounts such as Gmail, Outlook, Apple Mail or Proton, but Email Protection does not include a separate inbox. DuckDuckGo says it forwards messages without retaining the emails or their headers on its systems. Replies use the Duck Address, though the service cannot guarantee that message text will not expose the forwarding address or other identifiers. It is listed for Android, iOS, macOS, Windows, web and browser extensions.

EmailAlias.io creates private forwarding aliases so services do not receive a user’s real email address. Mail forwards to an existing provider such as Gmail, Outlook, ProtonMail, Yahoo, or another inbox. Sender exposure scoring looks for risky domains, typosquatting, phishing keywords, and other leak signals, while machine-learning spam detection blocks phishing, malware, and unwanted mail before forwarding. The service says it does not read, analyze, or store forwarded message bodies or attachments and keeps delivery metadata; email metadata logs are retained for 90 days. Premium users can add up to five custom domains, send and reply from aliases, and use the REST API and MCP access. The Free plan includes 10 aliases. Premium costs $4 a month. Browser extensions support Chrome, Firefox, and Edge; no mobile apps are listed.
