A number of admin-facing and subscription-related templates prefix the subject with the name of the kitchen (reseller) the order or subscription belongs to, so staff can immediately tell which kitchen it relates to. Examples: Admin: Order Create ("KitchenName: New Checkout #123"), Admin: Order Refund, Admin: New Registered User, Bag: Returned ("KitchenName: Bag Returned"), Admin: Recurring Proposals Auto-Charge Error, and the subscription pause/cancel/skip/change-address emails and their admin/request counterparts.

• Admin-facing versions use a colon style, e.g. Admin: Cancel subscription sends "KitchenName: Cancel subscription #123"; the matching customer-facing version wraps the name in brackets instead, e.g. "[KitchenName]Subscription Cancelled #123".
• The prefix is pulled from the kitchen's name on the order/subscription record; if that name isn't available on the record the prefix is simply left off and the subject starts with the normal text.
• Not every template does this - the main customer-facing order confirmation, Admin: New Lead, and several other emails do not include the kitchen name at all.

There is no setting to turn this on or off; it follows automatically from the order or subscription's kitchen record. In the current version this shows up most noticeably on multi-kitchen (reseller) accounts, since that's where distinguishing which kitchen an email is about actually matters, but nothing in the code we found gates the prefix specifically to multi-kitchen accounts - it depends only on whether a kitchen name is present on that record.
