Dr., Mr., Ms., Mrs., First Name, Last Name

What is the proper way to address someone by e-mail? It all depends on your relationship and how well you know the person.

If you don't know them very well, always use the highest level of formality Mr., Mrs., Ms., Dr., etc. Especially in business, you don't want to get too informal too soon. Formalities are in place for reason as they reflect courtesy and respect for the other side. You will be able to tell if the other side is ready for a more informal tone by how they sign off their e-mail. Follow their lead and you'll never go wrong!

Also, be sure to not assume how names are spelled. I have those who go informal on me who don't know me that well and address me as "Judy." For the most part, I'm "Judith" but with those I know very well and that I have an established relationship with, I will sign off my e-mails with a "Judi." If you knew me well enough to take the liberty of informalizing my name you would know that.

Try to also avoid the first name, last name trap. Some programs will insert names for you. When I get addressed as "Dear Judith Kallos", I know there is an automated process involved and the message is in no way truly personalized to me. Nobody addresses you like that with your first name and last name!

How you start your e-mails will set a tone and level of formality that can lead to positive relationship building. Don't make the mistake of misusing this opportunity.
