You may or may not be aware of proper Email etiquette when reaching out to your professional connections. Sometimes (or maybe all of the time), you may have a difficult time determining the balance between appropriate and dry (or boring) and interesting (which may teeter on less formal).

It goes without saying that you should never write anything that is obviously inappropriate or offensive How to delete a labels in gmail. However, it is often acceptable to be less than formal (stiff) and to even inject some humor into your Emails (where it fits naturally). You may be asking at this point if your readers will find humor and informality appealing and if it will make them want to read more of what you are sending them.
Well, it seems that some readers respond positively to Emails that have a formal tone. To those readers, a formal tone means that the person who wrote the Email is bright, educated, and is a subject matter expert.

However, on the positive side, that reader also perceives that the person is creative.
When it comes to the sexes, men take the writer more seriously if the tone of the Email is formal and drier. Women, on the other hand, often think that an Email that is lighter is more genuine. To many women, that means that the writer is dependable as well. If the writer uses jargon or sophisticated language in his or her Emails, the women often do not feel that they are comfortable with that.
