SimpleLogin | Open source anonymous email service | WarmIndex

SimpleLogin is an open-source email alias service that lets you create disposable email addresses to protect your real inbox from spam, phishing, newsletters, and data breaches.

🚀 Overview

SimpleLogin solves the problem of exposing your real email address when signing up for services online, which leads to spam, phishing, and privacy invasions. By providing unlimited email aliases that forward emails to your main inbox and allow sending replies without revealing your true address, it keeps your identity private.

It's built for privacy-conscious individuals, developers, journalists, and businesses worldwide. Launched in 2020 by a Paris-based team and acquired by ProtonMail in 2022, SimpleLogin was created to offer a transparent, open-source solution for email privacy in a world full of data-hungry services—prioritizing user control, no ads, and self-hosting options.

With apps, extensions, and web access, it's seamless across devices, now enhanced with Proton Pass integration for password management.
