The way the first D-Mail changed the world is by alerting SERN to the presence of a Time machine, they do not notice the existence of the first D-Mail until after 2010 so if it is deleted before it is noticed then the world line returns to normal. Daru receiving the Dmail does not change the worldline but SERN noticing it does.
