Subject: Your suggestions are valuable
I have a request.
As you know, we are always looking for opportunities–they are the blood of our business. Whether it’s an opportunity to better serve our customers, to make working here easier for you, or to expand into a new market, they are all highly valued.
I am writing because I know that your are often in a better position to perceive these opportunities than I am. I encourage you, thus, to voice your suggestions. [STATE HOW SUGGESTIONS SHOULD BE SUBMITTED, ex. I will indeed be delighted to hear them at your convenience.] {MENTION INCENTIVE, IF ANY, ex. We will be awarding a “Best Suggestion” award on a yearly basis, with this year’s winner receiving a weekend vacation to Lake Havasu.}
