Alternatives to SimpleLogin
Proton's open source alias service
SimpleLogin ranks #1 of 10 in Email alias services, with an Alt Score of 100. It is licensed under AGPL-3.0, freemium from $36/year and available on Web, Browser extension, iOS and Android. 9 of 9 checklist rows are verified against a public source.
Privacy-conscious people who want to stop handing out their real email address when signing up for websites, and developers or organizations who want a self-hostable aliasing system they control.
Unlimited email aliases that forward incoming mail to your real inbox without exposing it. You can reply or send new mail from an alias, and recipients only ever see the alias address. Supports custom domains, catch-all aliases, PGP encryption, and 2FA (TOTP/WebAuthn). Available as browser extensions and iOS/Android apps, and the code is open-source and self-hostable via Docker.
Each alias is a real forwarding address: mail sent to it is relayed to your actual inbox, and when you reply, SimpleLogin generates a per-sender reverse-alias that strips your real address and sends the reply from the alias instead, so the other party never sees your true email.
