Why to write emails? Why can not they talk to us telepathically?

I am talking to a Yahyel, a Pleiadian, a Blue and a Lyran via a channeler. They and their peers talk to each other telepathically but have real trouble reading human minds. They are able to talk to very few talented humans but the minds of over 99% of humans are inaccessible to them. They can read physiology, emotions, and health and they can talk to the human’s higher self but they can not speak to over 99% humans telepathically – neither remotely nor face to face. This is why the colonies are working primarily on development of telepathic abilities of volunteers.
