My CoE was just issued but it’s digital and says “do not submit to Embassy.”

Hi! I just received my CoE from my school. It’s digital and says “For confirmation only. Do not submit to embassy” but on all the student visa application guides it says to also mail my CoE. Will I be getting another digital one that I can print and mail? Will i be getting a physical one? Sorry, super stressed about this since i’m hopefully moving literally next month. Thank you 😀
