Stop handing your real email address to every website. Mailcow Aliases creates disposable forwarding addresses in one click, powered entirely by your own Mailcow server. No third-party service touches your data.
Right-click any webpage (or tap the toolbar button on iOS) and a new alias is ready instantly. It forwards to your real inbox. When you are done with it, disable it or let it expire automatically. Your primary address stays hidden.
WHO THIS IS FOR
You run your own Mailcow server and want a fast, native way to create and manage email aliases from Safari. No third-party service sits between you and your server. Your API key is stored locally in the system Keychain, and all communication goes directly to your Mailcow instance.
Unlike cloud-based alias services, your aliases live on infrastructure you own and control. No subscription fees to a middleman. No trust required.
HOW IT WORKS
Right-click on any webpage (or tap the toolbar button on iOS) to generate a new alias. The alias forwards mail to your real address. Use it for signups, shopping, newsletters, or anywhere you want to keep your primary email hidden. When you are done, disable or delete the alias.
