That way, every issue you're concerned with gets equal consideration from the legislator. State your reasons for supporting or opposing the bill. If the bill will affect you personally, briefly explain how. Seventh, and most importantly, tell them what you want them to do. Sign the letter.
Handwritten letters are okay if they're legible.
DO be brief and to the point. Limit yourself to one page only. DO keep trying. If you don't get a response indicating that your legislator is going to work on your issue, write once every three months, and no sooner. You will do more harm than good if you turn into a pest or become discourteous or disrespectful.
