What does a message written in all CAPS signify?

A message written in all capital letters is generally perceived as a form of emphasis, which can often come across as shouting or yelling in written communication. This convention stems from the fact that uppercase letters are visually more prominent and can convey a sense of urgency or intensity. In digital communication, particularly in emails or text messages, using all caps can be interpreted as aggressive or overly forceful rather than enthusiastic. Therefore, it is advisable to use all caps sparingly to avoid misunderstandings about the tone and intent of the message.
