To make your readers receptive to your arguments, these words will work in your favor. Just be sure you are using them honestly and appropriately:
Yes, free, easy, help, results, now, love, discovery, guarantee, money, save, sale, benefit, safety and proven.
Avoid no, can’t, won’t, shouldn’t, and other negatives. Instead of writing, “We cannot refund your money until you send us the correct form,” a more effective approach to the same idea would be, “As soon as you send us the corrected form we will immediately refund your money.”
