Actually, there are three:
1. You must allow us to write copy we think will sell.
You must agree to give us creative freedom. If you alter the sales page or email sequence we deliver, we cannot guarantee successful results.
2. You must be in need of better copy.
If your sales pages and emails are already pulling blockbuster sales number, there's no need to retain our services.
But, if you're like the majority of businesses who aren't happy with their results, or who don't have time to write your copy, we can help.
3. You must agree to provide us detailed data after you test our copy as well as a testimonial we can use to retain more business in the future.
We believe in "scientific advertising" based on actual tested results. We cannot help you sell more without accurate data.
