SimpleLogin is an open-source email alias service developed by SimpleLogin, designed to protect users' primary email addresses by generating unique, disposable aliases for every online service they interact with. Its primary workflow involves users creating a new email alias (e.g., random-string@simplelogin.com) when signing up for a service, which then forwards all incoming emails to their real inbox, allowing them to disable or delete the alias if it starts receiving spam or is compromised. Accessible via a web dashboard, browser extensions (Chrome, Firefox, Edge, Safari), and mobile apps (iOS, Android), providing seamless alias management and creation across devices. The most-used feature is its ability to instantly generate a new, random email alias directly from a browser extension when signing up for a website, ensuring that the user's real email remains hidden from third parties. SimpleLogin processes email forwarding without storing the content of forwarded emails long-term, and implements encryption for sensitive user data, maintaining a strong commitment to privacy, with its code being open-source and publicly auditable.

Why It’s Useful
SimpleLogin eliminates the pervasive problem of email spam and the security risk of your real email address being exposed in data breaches, allowing users to control who can send them emails and to instantly cut off unwanted senders. An online shopper can use a unique SimpleLogin alias for every e-commerce site, and if one of those sites suffers a data breach, they can simply disable that single alias to stop any incoming spam without impacting their main inbox. A developer testing new SaaS applications can create a new alias for each signup, easily managing multiple accounts and quickly deactivating aliases that attract spam or are no longer needed. SimpleLogin offers a very generous free tier with up to 10 aliases and unlimited bandwidth, while a paid Premium plan (starting at $30/year) provides unlimited aliases, custom domains, catch-all mailboxes, and PGP encryption, billed annually. It often surpasses similar alias services by being fully open-source, offering robust integrations with popular password managers like Bitwarden and secure email providers like Proton Mail, and providing a transparent, privacy-focused business model. Advanced users can configure custom domains for their aliases, allowing them to create professional-looking aliases like service@mycustomdomain.com, which still forward to their personal inbox while maintaining brand consistency. The learning curve for basic alias generation and usage is low, especially with the browser extension, making it easy for most users to adopt, though configuring custom domains or advanced PGP encryption requires a moderate technical understanding.
