OPC Mail vs Shroud.email

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.

Shroud.email creates email aliases that forward incoming messages to your real inbox, keeping the real address private. It removes tracking pixels from forwarded mail and proxies email images through its servers. You can delete or disable aliases and block individual senders, and the service says it works with all email providers, including Gmail and Proton Mail. Paid users can attach custom domains, configure catch-all aliases, and recreate those addresses elsewhere if they leave. The API manages aliases and discovers custom domains with bearer-token authorization. The project is open source under AGPL v3 and includes a Docker Compose deployment for self-hosting. Self-hosting requires a public server with ports 25, 80, and 443 open, plus keys for S3-compatible storage. Detected spam remains viewable in the web portal for seven days. The hosted service is EU-hosted on renewable energy. The Free plan costs nothing and includes five aliases and tracker blocking; the paid plan has no listed price and renews annually.
