About SimpleLogin
SimpleLogin provides email aliases that forward mail sent to the alias to your inbox. You can reply to forwarded messages or send new messages from the alias, so recipients see the alias address.
It supports custom domains with catch-all addresses, subdomain addresses for creating aliases on the fly, use with multiple mailboxes, PGP encryption before forwarding, and account login with TOTP or WebAuthn. Aliases can be managed through the website, browser extensions for Chrome, Firefox and Safari, and apps for Android and iOS.
