I bought one .edu, the seller delivered and the e-mail works. In particular I was looking for an .edu e-mail that would allow me to obtain an AWS Educate starter account. I tried some other .edu e-mails before and none of them worked for this purpose (Amazon somehow didn't see them as valid .edu e-mails). This e-mail from Zoomer does work! Most people probably don't care about some AWS Educate starter account but the fact that it passed Amazon's verification might indicate it will work elsewhere as well.
