What EmailAlias.io is
EmailAlias.io creates private forwarding aliases so sign-up services do not need a user's real email address. Messages are forwarded to an existing inbox, such as Gmail, Outlook, ProtonMail, Yahoo, or another provider. Its exposure intelligence scores senders using signals such as risky domains, typosquatting patterns, and phishing keywords, while spam detection aims to block phishing, malware, and unwanted mail before forwarding. The service says it does not read, analyze, or store forwarded message bodies or attachments; it retains delivery metadata, and email metadata logs are deleted after 90 days. The free plan has 10 aliases, forwarding, and basic spam and leak detection. Premium costs $4 a month and adds unlimited aliases, up to five custom domains, anonymous sending and replies, exposure analytics, advanced spam protection, and REST API and MCP access. API access is Premium-only. Browser extensions are available for Chrome, Firefox, and Edge; Opera and Safari are listed as coming soon. EmailAlias.io lists web, extension, and API platforms, with no mobile apps.
