iMessage is the best option for Apple – Apple communications. This will mean if 2 people are using iPhones, iPads, or MacOS computers, then the communication will use iMessage. iMessage is Apple’s closed loop messaging platform for their devices only. It uses a data connection such as cellular or a network connection to the Internet.
If you have an Apple device, you would be able to use this to communicate with me. This is because my cellular phone is an iPhone, and while a couple generations old, iMessage is still supported. If you are using a computer, or a non-cellular iPad, the email address associated with your Apple ID will be the identifier. However, in my limited experience of using iMessage, I have never seen anyone using their Apple ID to send a message.
