How do I find the source of an RSS feed in Mac mail?

Factual Questions
1

I have a bunch of RSS feeds coming into my Mac mail. I realized today that one blog hadn’t been updated in a long time, and I wanted to go directly to the blog page to see what’s up.

Unfortunately, my name for the feed is an abbreviation, so I could not find the original blog via Google. Also, there seems to be no “Get Info” function for the individual feeds (i.e., doing an option click on them). But surely that information is somewhere, right? It has to go to the blog to find it.

Thanks for helping me find that info!

If you let your pointer hover over the name of the feed in the mail sidebar, the full URL will appear.

Thanks, that works. One would think that there would be some function to cut and paste that, tho.
