SimpleLogin
Open-source email aliasing and forwarding service
SimpleLogin is an open-source email aliasing and forwarding service designed to protect your real email address from tracking, spam, and phishing. It creates email aliases that forward messages to your mailbox and can also relay replies and outbound messages so your real address stays hidden.
Key Features
- Create permanent email aliases that forward to one or multiple mailboxes
- Send and reply from aliases via reverse-alias addressing
- Custom domain support, including catch-all style aliasing
- Browser extensions and mobile apps that can be pointed to a self-hosted API URL
- Optional PGP encryption of forwarded emails using your provided public key
- Account security features such as TOTP-based 2FA and WebAuthn (FIDO)
Use Cases
- Use unique aliases per website to reduce tracking and limit breach impact
- Hide your real address when contacting marketplaces, newsletters, or support
- Manage business-style addresses on your own domain without separate mailbox hosting
Limitations and Considerations
- Requires careful mail server and DNS setup (e.g., MX, SPF, DKIM, DMARC) for reliable deliverability
- Operating an SMTP service may require suitable hosting that allows outbound port 25
SimpleLogin is well-suited for individuals and teams who want strong email identity separation without changing their primary mailbox provider. It provides a practical, privacy-focused layer for receiving and sending mail while keeping your real address private.
