When reconciling my budget (with YNAB) I often use gmail as my way to connect items to transactions [0]. I've found that I can just search for the amount that my card was charged in my email and find the Amazon email that relates to that order. Then, normally from the body, there is just barely enough information for me to know what I bought.

That got annoying enough that I just wrote a chrome extension to scrape Amazon orders/transactions and auto-match and update my YNAB memo line with a summary of the items.

That's a bit of a tangent just to say: yes, they nerfed their emails but not completely.

[0] Yes, YNAB recommends that you enter transactions right as you make them, but that's not how I use it.
