In WhatsApp chat window, you will be able to see blue or Grey tick marks underneath each message to display the message status. When you send a new message, initially you will see One Gray tick ([themify_icon icon=”fa-check” icon_color=”grey” ]) that indicates Message Successfully Sent. Most probably in the same instance this will change to Two Gray ticks ([themify_icon icon=”fa-check” icon_color=”grey” ] [themify_icon icon=”fa-check” icon_color=”grey” ]) saying that Message Successfully Delivered to Recipient’s Phone. This Two Grey ticks will eventually change to Two Blue ticks ([themify_icon icon=”fa-check” icon_color=”blue” ][themify_icon icon=”fa-check” icon_color=”blue” ] ) confirming that Message Read by Recipient.
