How does the mail actually work?

I sold 1000+ items on the auction house and I can get only 50 mail with money on every 10-15 minutes. Still have 1400 messages not shown

Mailbox shows 50 mails at a time. It can be refreshed once a minute. There are addons like Postal that can collect your gold and keep refreshing mailbox automatically. But it won't work well if you still have the initial mails about item sold in your mailbox too - the ones that come without gold and tell you that gold will arrive later. Those usually disappear after server restart but you can also delete them yourself so you can load next mails.

So I can delete the pending ones without losing the money they grant?

Pending mails will always be empty. You get the money in new mail.

Quick way to delete empty mails is via this macro:

Code:

---

/run if atbmi==nil then atbmi=1 end atbni=GetInboxNumItems() if atbmi>atbni then atbmi=1 end atbit=GetInboxInvoiceInfo(atbmi) if atbit=="seller_temp_invoice" then GetInboxText(atbmi); DeleteInboxItem(atbmi) else atbmi=atbmi+1 end

---

You can test the macro on alt with cheap item in mail and 1 empty mail, if you're suspicious.

Alright, thank you!
