Emails are forwarded to your real email address. If you reply to a sender it will use your alias, too. It is designed to be user friendly and available on many platforms. Based in France.

A covered pick. Anyone can use it as a private drop-in, with no setup or know-how. Enough for most people. Threat levels
Our take
An alias forwarder rather than a mailbox, SimpleLogin lets you hand out a different address to every site and keep your real inbox hidden, and replies still go out from the alias so nobody learns your true address. It is now owned by Proton, which is reassurance or concentration risk depending on how you feel about putting more eggs in one basket. Reach for it as a layer on top of whatever email you already use, not as a replacement for it.

SimpleLogin license, in plain English
AGPL-3.0 Strong copyleft · network
Free to use, even commercially. Changes must be published under the same license, and running a modified version as a network service counts as distributing it.

Why it matters: The network clause is the point. Anyone who runs a modified version as a hosted service has to publish those changes, so the code handling your data stays inspectable. This is why privacy-first projects reach for AGPL.
