If you said you haven't you are just a dirty liar and should probably look at that in yourself.
But, I just found the coolest thing on it!
Email Thread Reply Notification.
That's right. Instead of just refreshing your email every ten minutes, you can set up a notification, with its own special sound and everything, to tell you when you heard back on that submission.
Go to the sent folder of your inbox, swipe left on your email submission. Tap "More". A list of options will come up. At the Bottom it will say "Notify Me". Tap that.
Now you're set up to be notified when you hear back. There's an automatically assigned tone for this, but you can go to settings and change the sound to something you don't use for anything else.
Ta dah! Now get out of your email and write!
