Every gold maker in World of Warcraft will spend time at the mail box. Indeed, players covering a mailbox with their mount and so making it hard to access the mailbox is almost considered an act of war!
Therefore, anything that can be done to speed up the unloading of mails is welcome. To that end, there are two things that can be done:
Firstly, the mailbox will allow you to unload the first 50 mails. To speed up this process press the “config” button on your mailbox page (assuming you have an addon such as Mail Opener)
When the Configuration window opens up - select the "Open All" as shown in the image above
And then set the opening interval times to the above - this is the fastest time to open 50 mails, assuming latency allows this.
Secondly, when you have more than 50 items to empty from the mailbox you need to wait a full minute before the mailbox loads the next 50 items to allow unloading to continue.
To skip this part you can put “/reload” in the chat box to reload your UI. If you computer is fast enough then this only takes a few seconds (for me about 8) – which is a great saving on the 30 seconds i normally have to wait.
Something that every serious gold maker needs to be aware of.
