Although this postcard's clean, straight-forward makes it compelling, the headline could be much stronger.

Instead of 'save up to 25%,' use the actual dollar value ... 'Save up to $1,096.25 off your electric bill every year.' It also makes it easier to justify the $499 price.

Any homeowner knows that saving $25 off of a project isn't much money. Make sure that the discount is compelling enough to make it a no-brainer for your prospects. It has to be more enticing. If the discount varies by the type of job, create a tiered discount offer like the one below. Structure the discount based on the amount of money the prospect spends. That's the only thing I like about the postcard below.

That's the big question your prospects are asking every time you send them a promotion. On the front of the card, it simply says, 'Talk to us before you buy!' Why? Why should a prospect talk to you? Do you offer better prices? Do you offer better quality? Are you going to save a prospect money? Then prove it and give your prospects a reason to believe you. What can you do that someone else can't? What's your Big Zig?

That's easy to answer in this case: They don't have one. In fact, the company suffers from menu-itis. Simply listing all the things you do doesn't tell a prospect what you can do for them. Tell your prospects how you can make their lives easier or better by giving them a clear, compelling benefit. Review your materials for menu-itis and simplify your promise.
