You really can't take rejection personally. Sure it would be nice to get feedback from potential clients, whether positive or negative, but you have to keep in mind that they too have a priority list. Each day people have to decide how they will spend their time - those things that represent the greatest need will take top priority followed by "wants." And the wants will fall into order of what they want more at that given moment. A person's priority list (of both needs and wants) is constantly changing, which is why repetition is so important in promoting a sales message. You just have to be lucky enough to hit them when your particular product or service is high enough on the priority list to compel them to act. But please don’t take a lack of action as a sign of disrespect. It just means they have other priorities that they deem more important at that time.

Also, it’s a lot easier to simply check a box expressing interest in more information, than to actually make a call – or even take the time to receive one. Yes it sucks, but that’s business. Your challenge is to create a message that puts the product/service you’re selling high on the clients’ priority list. If you cannot come up with a message or promotion to accomplish this goal, then it is probably time to consider a different product or service.
