My DD has checked with both teachers and neither have received it and she did this on Monday I believe. I'll have them check their spam folders. Thank you.
Yes they can go to spam quite easily, especially if they were sent to a "k12.xx.us" type of address. They are still sent basically instantaneously per GoNavyPro's description.
Some schools anti -spam even screen them out. you may have to use their private e-mail or work with a principal or someone to get it into the system and then to the proper teacher.
