Shop Addresses by mbr

Give every online shop its own e-mail address – created on the fly, right in the checkout form.

When you focus an e-mail field, a small button appears. It suggests the shop name from the website (e.g. gardenshop.example → gardenshop), has your mail server create a new address like m-gardenshop-2026-k3x9q2ab@your-domain and fills it in, including “repeat e-mail” fields. Addresses you already created for a shop are offered for reuse. The toolbar popup (also on Android) and a context menu (desktop) do the same.

Why? You see which shop leaked or sold your address, and you can shut down a single address on the server.

Requirements:
• A mail server offering the shop address REST API (open specification), e.g. Roundcube 1.5–1.7 with the plugin identity_api: https://github.com/michael-dev/roundcube-identity_api
• A personal access token from that server (in Roundcube under Settings → Preferences → Shop address API, one click with “Connect browser extension”)

Privacy: The extension only talks to the server whose API URL you configure. It sends your access token and the shop name and receives the generated address – nothing else leaves your browser, no analytics, no third parties. The user interface is in English and German.
