I am very sure that, whatsapp does not need any introduction. Everyone that possesses smart phone uses whatsapp for messaging and calling purpose. Just the internet connection is enough to send messages or make a call to anyone that is either in your country or overseas, this is why people would love to use whatsapp the most while comparing to other chatting applications. We all know how to send messages to our contacts, but do you have any idea about sending messages to the people that are not in your contact list.
Whatsapp introduces a new feature called “click to chat”. With this feature, you can start a chat with the people that are not in your contact list too. Hereafter, saving the contacts is not necessary to send messages. The point is that, you have to know the contact number of the person you want to message to, which is mandatory.

You have to click the link to start a chat with the person that is not in your contacts queue. This chat feature functions on both whatsapp web and phone.
