Alias Email vs DuckDuckGo Email Protection

Alias Email creates alternative email addresses that forward messages to a primary inbox, helping users keep their main address private and organize incoming mail. Aliases can use personal or business domains, send anonymous email, and forward to multiple recipients. The browser extension can generate an alias from an email field, including in website forms, popups, modals, and online chats; it is listed for Chrome, Safari, Firefox, Edge, Opera, Vivaldi, Brave, and Tor. Alias Email says it removes trackers from forwarded messages and allows a PGP public key to encrypt messages before forwarding, while the user keeps the private key. Forwarded mail is not stored except during service outages, when it may be held temporarily for up to three days. The service says it uses TLS, SPF, and DKIM, is GDPR compliant, and does not sell or disclose user data. Its free plan includes 10 aliases and one custom domain. Premium costs $39.96 a year, equivalent to $3.33/month billed annually, and includes unlimited aliases and two custom domains. There are no mobile apps.

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.
