Manage your list. 
Keep your list as current as possible, taking out any returns or those who opt out as mail going to the wrong address. Someone who is not interested is a waste of time, money and resources.

Stay on Track. 
Always check your objectives, the purpose of direct mail is to drive sales and encourage new business. Evaluate the effectiveness of your campaign based on the return on investment.

Be realistic. 
Response rates to direct mail are generally no more than about 1 to 2% so don't be discouraged if a campaign that receives this sort of response as being a failure.

Tease your prospects. 
A teaser campaign is a sure-fire way of getting people's attention and by using more than one direct mail pieces, usually at least three, within a short period of time you are able to build a sense of excitement and ambiguity before revealing the final message.

Keep it simple. 
Don't hassle people with different messages, know exactly what you want to say and think about how to do so clearly.

Deadlines. 
Create them and stick to them. Especially during a teaser campaign, timings need to be thought about carefully and direct mail needs to hit the desk at the right moment and in quick succession.

Know your target market.
Research who they are and where they are. Find out if they are mainly male or female and their age range. All of these details will help you to better target them with your campaign.
