What is the correct salutation when writing a business letter to a Lady?
To be honest it all depends upon the lady to which you are addressing the business letter. If you don’t know much about her, it can be hard to choose. I prefer Madam, no e on the end of it. An e on the end of the word madam, puts things into mind that are far from business oriented. And, when using Madam, do not use her name, use her title. Such as President, Vice President, etc.
