In building a product it must have taken you lot of research, hard work, money and lot of valuable time of you and your team members. So its launch has to be properly planned and executed. You have to do lot of brainstorm as success and failure of your product is based on it.
An effective an impressive first impression can give you long lasting results.
There is no pint in leaving any stone unturned and regret later. You must have seen on some blogs posts regarding what went wrong in their product launch. I must let you know that not having a detailed contact management software to manage all your contact also plays a role here. While many are there who releases their product without any one hearing a buzz about it.
