Buying online leads to many emails being sent for Order Confirmation, PayPal activity, Item Shipped and even returns. These emails share Transaction numbers and Item-ID numbers.
I would love to have Email Client plugin to collect related emails on a Transaction or Item basis – then managing my orders would be a breeze. I buy a lot of electronic parts from eBay and Amazon via my PayPal account.
I suspect that online shoppers would appreciate an email solution that accomplishes the above tasks.
