第三步：To offer conviction
通过产品介绍引起读者的购买欲望后，就该进一步加强读者购买的决心。你可以详细说明并保证产品会给读者带来许诺的好处。且看下面这段内容是如何吸引客户的：
1) Use our Fast Microwave Oven for two weeks absolutely free.
2) If for any reasons you find the model machine unsuitable to your needs, we will replace your order or refund you.
第四步：To motivate actions
到了这一步，所有的努力都指向一个目标：促使客户采取行动、购买产品。这时语气要礼貌坚决，并提供给客户如何购买产品的指示，以方便客户购买。下面是一些常用的策略：
1) Why wait? Come and buy right now since a special discount of 15% will only be offered for a month.
2) Don't delay! Those who order by October 5 will receive 100 Oriental Design Christmas cards free.
