Hi Sara: I went to my email provider and checked email on their computer, nothing. I reset their junk mail setting so that they don't automatically delete them.
Some ISPs block emails at their level based on things like the sender's address (whether or not it agrees with the other information in the header, whether or not it contains certain "loaded" terms such as sales in it, et cetera), loaded words in the subject, sometimes even based on the originating location/server. They're not supposed to arbitrarily block emails that are direct replies (IOW, an email that would otherwise be blocked would not be if one of their customers has recently(+/-) first sent an email to that exact account), but accidents have been known to happen. Yahoo, for example, has been known to block large numbers of emails from businesses that sent them to Yahoo email accounts - these account holders were actually customers of those businesses, lol, and the emails were important announcements instead of spam, but... IDK exactly why it happened in those three cases; perhaps because a certain number of emails had been sent to Yahoo accounts from the same email address (or domain) within a 24-hour period or something. But I would contact your ISP (or email provider's, if different) and ask if any email sent (specifically from the two email addresses that the rep has stated emails were sent to you from) to your email account might have been blocked at its level and, if so, will they add those email addresses as exceptions to their blacklist so that future emails will go through. They might be able to get the missing emails to you, but I would not count on it (or at least not on whoever it is that you contact being willing to do so).
