DuckDuckGo Email Protection vs OPC Mail

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.

OPC Mail is an email alias service for a domain you own. After you point the domain’s MX records to Cloudflare in a one-time DNS change, any prefix at that domain works immediately, without creating aliases in advance. This lets one-person companies use separate addresses for service registrations, newsletters, online shopping, and beta testing or QA while keeping a main inbox organized. The service says it has no tracking or ads, does not sell user data, and does not use AI to read mail. OPC Mail describes itself as fully open source and links to its GitHub source code. It reports average delivery of 2–5 seconds using Cloudflare Edge and a global CDN. The Free plan costs nothing and includes unlimited aliases per domain. An iOS app checks the inbox; web access is also listed.
