What SimpleLogin does
SimpleLogin is an open-source email alias platform founded in 2020 by Son Nguyen Kim and headquartered in Geneva, Switzerland, under parent company Proton AG (which acquired it in 2022). The company operates a French subsidiary, SimpleLogin SAS (SIREN 884302134). Its product allows users to generate disposable or persistent email aliases that forward to a real inbox, with the differentiator of supporting bidirectional send-and-reply from aliases via reverse-alias technology, plus PGP end-to-end encryption and 2FA (TOTP/WebAuthn). Distribution is fully self-serve across Chrome, Firefox, Safari, and Edge browser extensions, iOS and Android apps (including F-Droid), and an open-source codebase on GitHub, allowing self-hosting via Docker.
The platform serves primarily privacy-conscious individual consumers (over 1,000,000 users and 800,000+ aliases created), with secondary use by small businesses managing custom-domain email and by web developers using 'Sign in with SimpleLogin' as a privacy-preserving identity provider alternative to social-login SDKs. Revenue is generated exclusively through a freemium subscription model: a free tier (10 aliases, unlimited bandwidth, 1 mailbox, mobile and browser apps) and a premium tier at $36/year or $4/month (unlimited aliases, custom domains, catch-all, subdomain aliases, reverse-alias, PGP, unlimited mailboxes), with discounts for students, journalists, activists, and charities. Payments are processed via Paddle and Coinbase Commerce, and an official reseller (ProxyStore) sells coupon-based subscriptions.
The company's strategic positioning rests on four pillars: (1) full open-source transparency to win trust in a privacy-sensitive category, (2) Proton AG ecosystem integration for distribution and infrastructure leverage, (3) zero-data architecture (no email content is stored) as a defensible moat against data-monetization competitors, and (4) product-led growth with zero human sales involvement. Headcount is reported at 1–10, indicating a lean operation whose costs are largely absorbed by Proton AG. Upcoming roadmap signals include phone number and credit card aliasing, extending the core concept beyond email.

SimpleLogin is an open-source email alias platform that lets users create alternative email addresses so the real inbox is shielded from spam, phishing, and data breaches. Emails sent to an alias are forwarded to the user's real mailbox, and via reverse-alias technology users can also send and reply from the alias to keep their real address hidden. The platform is delivered through a web app, browser extensions, and mobile apps, with a privacy-focused identity provider ('Sign in with SimpleLogin') and a self-hostable Docker deployment for full control.

SimpleLogin competitors and assessment
Company assessmentBroad incumbents
- Apple Hide My Email: Apple's email alias feature bundled with iCloud+ (and integrated with Sign in with Apple). Competes directly on the core email-aliasing use case but is a feature within Apple's broader subscription suite rather than a standalone product.
- Proton Mail: SimpleLogin's parent company and a privacy-focused email provider. Proton Mail now offers built-in aliasing, creating both a cross-sell channel and a partial internal substitute for SimpleLogin's core use case.
Direct peers
- 33Mail: Long-standing paid email alias and forwarding service with custom-domain support. Targets the same use cases as SimpleLogin Premium (infinite aliases, custom domains) and competes on price and feature depth.
- Addy.io: Open-source, self-hostable email aliasing platform with a similar freemium model and feature set (custom domains, catch-all, PGP). The closest open-source competitor to SimpleLogin's value proposition.
- Forward Email: Open-source email forwarding service with custom-domain support. Targets the same 'privacy + custom domain email' audience as SimpleLogin, including a developer-friendly self-hosting option.
- Burner Mail: Email aliasing service that creates disposable and reusable aliases to protect a user's real inbox. Directly comparable consumer-facing alternative with similar freemium positioning.
- Firefox Relay: Mozilla's email alias service that creates masked email addresses to protect the user's real inbox. Closest direct competitor to SimpleLogin and explicitly compared on SimpleLogin's own comparison pages.
- DuckDuckGo Email Protection: DuckDuckGo's free personal email aliasing and tracker-removal service. Targets the same privacy-conscious consumer segment as SimpleLogin with a free-tier offering that competes on price.
- Abine Blur: Privacy-focused service offering masked emails, phone numbers, and cards. Overlaps with SimpleLogin on email masking and targets similar identity-protection use cases for consumers.
Emerging players
- IronVest (Abine): Privacy and identity-protection platform built on Abine technology, offering masked emails as part of a broader digital identity suite. Represents an adjacent emerging competitor extending aliasing into broader consumer identity protection.
