What OPC Mail is

OPC Mail is a free email service for domain owners who want separate addresses for different services. It provides catch-all aliases on a configured domain, so any prefix at that domain works without creating or registering aliases first. The site presents these aliases for service sign-ups, newsletters, online shopping, and beta testing or quality assurance. OPC Mail is aimed at one-person companies that want to keep a real inbox organized while using service-specific addresses. The service says it has no tracking or advertising, does not sell user data, and does not use AI to read mail. It describes itself as fully open source and links to source code on GitHub. Setup requires your own domain and a one-time change to point its MX records to Cloudflare. The site reports average delivery in 2–5 seconds. An iOS app is available for checking the inbox. The Free plan costs nothing and includes unlimited aliases per domain.
