I don't know, more power to you. I don't see any real downside. The same as motivational quotes or proverbs or affirmations are delivered via email, calendar, app, tweet or any other subscription service, I see no reason a hypnotic text could not be added to the list.
Just don't steal my hypno-cookie idea, lol.
Edit:
