GhostRelay vs SimpleLogin

GhostRelay is a web service that creates email aliases and forwards their messages to a real inbox. Users can make random or custom aliases, monitor them, and disable or delete them from a dashboard. The free plan costs nothing, requires no credit card, and allows up to 20 aliases with unlimited forwarding, custom names, and enable or disable controls. Forwarded messages preserve the Reply-To header, and the service supports replying from an alias. Mail can be sent to any receiving address, including Gmail, Outlook, Yahoo, ProtonMail, and iCloud. Disabled aliases reject incoming messages and return a bounce to the sender. GhostRelay says email is processed in memory without disk or database storage and content is not retained. It describes TLS 1.3, AES-256, bcrypt hashing, and signed JWT authentication. Custom domains and a browser extension are available; mobile apps and a public API are not.

SimpleLogin creates email aliases that forward messages to a mailbox while keeping a user's real address hidden. Users can reply to messages or send mail from an alias. Aliases can be created with a subdomain or catch-all domain, and users can bring their own domain. With PGP enabled, messages are encrypted with the user's PGP key before forwarding. Accounts support TOTP and/or WebAuthn two-factor authentication. SimpleLogin says its components are open source and can be self-hosted. It lists Chrome, Firefox, and Safari extensions, plus iOS and Android apps, including Android through F-Droid. The Free plan costs nothing and includes 10 aliases, one mailbox, and unlimited bandwidth; users cannot create more aliases after reaching the cap. Premium costs $36/year or $4 billed monthly, and includes unlimited aliases, custom domains, and mailboxes, plus PGP encryption. Free and Premium plans include the corresponding Proton Pass features. SimpleLogin says it joined Proton in early 2022.
