Often the first contact you have with a prospective client is by letter.  Now, in the world of first contact letters there is "Good", "Better", and "Best".  "Good" is what you might expect, a "Hi, I’m so and so and I’d like to talk to you about our interiorscaping service".  "Better" goes the next step forward and adds to the first info about "who we are", the awards you’ve won or the organizations you belong to. 

Then There’s "Best"
A letter that gives the reader an idea of why they should be talking to you, reasons like saving money, receiving prompt, professional service and so on.  In other words, how they will benefit by using your company.

Attention, Attention
You’ll also need an attention grabbing headline that offers a major benefit and follow up with a paragraph that supports it.  The letter shouldn’t be too long, one page max, easy to understand and to the point.  Personalize your letter by writing in a friendly, courteous tone and include a call to action or state that you’ll be calling soon to follow up, then, do it.

Customize
I recommend having three or four different letters each targeting a different market segment such as Hospitality, Office, Property Managers,Residential, and so on.  That way you can concentrate on the benefits you offer to each group.  Example: Offices?  Your attention to security issues.  Hospitality?  Maybe you have a Floral Division.  You get the idea.

Take A Look At the Letter You are Currently Using.
Does it talk benefits or just brag about how great you are?  Hmmm.  Maybe it’s time to revise them.
