Annoyingly this is frequently not the case for email notifications. This means that you either need to view full headers and find the appropriate ones, or click on the link to look in your web-browser, in order to obtain sufficient context to realize that you can just delete the notification. It would be useful is Product and Component were displayed in the bugmail body Reproducible: Always
There are actually a lot of places that add this as a customization. Perhaps it would be good to do something like it.
You don't need to view full headers. Only X-Bugzilla-Product and X-Bugzilla-Component. This way, you don't them in the body.
We add product/component to the email template every time we upgrade.
X-Bugzilla-Product and X-Bugzilla-Component are already available in bugmail headers, and Bugzilla 4.4 has a hook to add additional stuff in bugmails, see bug 735332. Some installations prefer to have this information in the Subject field and can already use extensions to achieve this. So you can achieve what you want thanks to an extension and you don't need to reimplement this every time you upgrade.
