Previous years showed us that Black Friday (often paired with Cyber Monday) becomes more and more popular as an opportunity to make a great deal-hunting right before the Christmas madness. It’s also the best time for businesses to creatively promote their products and make some seasonal sale of stocks. Although this year is not encouraging customers to visit hundreds of shops for a price deal, it made many companies focus on their online sale. That’s why we’ve created some email signature designs for you to help you easily promote your Black Friday and Cyber Monday offers.
