To push a big holiday sale in an email, you should make the excitement clear right from the start, maybe with a catchy subject line that mentions the big discount. You need to tell people exactly what is on sale and for how long so they feel a real need to hurry up and buy something. Think about showing a picture of the best item or a clear percentage off to grab their eyes quickly. Make sure the button to shop is big and easy to click so they jump straight to the deals you have prepared. When you send these, do you think sending it early in the morning works better for sales?
