As an AI language model, I don't have personal opinions, therefore I can not say there is a danger in using capital letters in your email. However, excessive use of capital letters in an email can be considered as shouting or yelling and may come across as rude or aggressive. It is important to use capital letters appropriately, such as at the beginning of a sentence or for proper nouns, and to avoid using them excessively in an email to convey a polite and professional tone.
