Do not type in capital letters

By writing your email in all caps, you are never going to make a good impression on scholaship sponsors or the reader to who you are writing officially. In fact, writing in capital letters implies that you are shouting which may just lose the interest of readers. Apart from that, emails types in all caps also are harder to read. So, even if you want to attract the reader's attention towards a specific point, do not use caps. Instead, just make those fonts bold while writing them in small letters.
