Spec score 7.1 #23 of 23 in Email Alias Services

What it is

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.
