About digital pre orders what is it like?

Hi I'm someone who is no stranger to buying from Gamestop but I am fairly new to the new Pro membership and buying games digitally off of Gamestop (I actually just bought Luigi's Mansion 3 yesterday to use my 5% off) but long story short I've preordered Mario Kart World and I would just like to know when that email containing the code would arrive so to the people who have digitally pre ordered games when do you all receive your emails? Is it when the clock hits 12 or is it later into the day? And yes I am aware that there might be a new system of how they roll out codes because it is a Nintendo Switch 2 game but I would just like to know from some first hand experience of what it is like. Thank you!
