Are you having an hard time remembering which of your toon should receive herbs (but only a certain type), while another one need ore but also pelts? And pet charm.. where am I storing them?
Mail Commander allows you to define a per character list of needs which wil be displayed when you open the sendmail panel allowing you to send all requested items or just some of them.
You can make this selection permament, disabling some kind of items, or just cherry pick each time
You can also use the "Send all" button to have all enabled items sent with a single click
