Autofill Yellow Letters?

[Kevin Ferris]

Maybe a dumb question, maybe not, but I'm just getting started in direct mail marketing.

So I have a letter written up in Microsoft Word...I want to personalize them with the owners name and address of the property in the content of my letter.  Obviously, doing this for hundreds of properties is going to take quite a bit of time.  Any Word gurus out there that know of a quick hack?  I have my address / property owner list in Excel.

Is it more of just creating a master file the hard way, and then updating the file as you add and delete properties?

Like I said...might be a dumb question, but that's never stopped me before.
