Mailcow Aliases

Create disposable email aliases from Safari using your own Mailcow server. Use separate addresses for signups, shopping, and newsletters, then disable or delete them when you no longer need them.

On Mac, right-click a webpage and choose Generate Mailcow Alias. On iPhone and iPad, open Mailcow Aliases from Safari's extensions menu and tap Create Alias for This Page.

FEATURES

- Three alias styles: random characters, realistic names, or site-based names
- Fill email fields and copy newly created aliases
- Choose an alias lifetime for automatic cleanup
- Silent discard mode to accept mail without delivering it
- Add notes to remember each alias's purpose
- View, enable, disable, and delete aliases from the Safari popup
- Choose from available domains on your Mailcow server
- Save your connection settings locally, with the API key in the system Keychain
- Dark interface for Mac, iPhone, and iPad

YOUR SERVER, YOUR ALIASES

The extension communicates directly with the Mailcow server you configure. Alias records, optional notes, the associated website hostname, and expiration timestamps are stored on that server. Connection settings and your API key are stored on your device. The extension includes no advertising or analytics.

Automatic expiration removes aliases when Safari is running and your server is reachable; it is not a guaranteed delivery cutoff. Safari may require another tap on Copy after creating an alias.

Requires a Mailcow email server with API access enabled, available alias capacity, and a valid forwarding address. Supports Safari 15.4 or later on macOS Monterey and later, and iOS/iPadOS 15.4 or later.
