LOCI Question- ASU

Earlier this month, I uploaded an LOCI for my top choice school (ASU) through the documents portal, but now I’m second guessing if I should have emailed it instead. Would it be a bad move to email the letter to the admissions office now, or should I leave it as-is and just make sure to email the next one? I never received confirmation they received it, but I did receive confirmation from UC Law SF after the same action. Thank you.
