Is the Message spell telepathy?

@JeremyECrawford actualy, better phrasing would be, is message telepathy in nature or do both creatures have to have the sense of hearing?

The message spell isn't telepathy. The caster literally whispers a message that the target hears if able. #DnD https://t.co/OQSYI21zdE
