Use emails labels to keep track of what's going on.
"Waiting people": you're waiting for people to answer an email you sent. Once a week (during your weekly review), politely ask again for an answer.
"Waiting action": something needs to be done before archiving or answering it. Link this label with your to do list.
"Waiting answer": do your best do keep this one empty. It's the one that will contain the emails you should have replied to, but you were to busy when you red them.
"Read later": informative emails you don't need to read right away but would like to read later.
