Background
This morning, an email was sent to one of my folders at 9:32a.m. I didn't get around to checking it until our team standup at around 9:45 which I volunteered to lead the day before. As I was in the middle of checking my email, my boss states to me "Did you ignore the email I sent?" as I was reading it. Not knowing how to respond, I just said "Oh ok.." then hung up the phone and ended the standup meeting.
Issue
I am afraid this will show up on my performance review as " ignores important emails", when it was really just an honest timing mistake. Hence my question.
Question
Given the situation above, would it be reasonable for my manager to state negatively on a performance review that I "ignore emails" or "ignore important emails"?
Edit:
After speaking with my boss, it turned out it was a joke that I took too seriously. To answer your question he hasn't set any expectations for email setting, and it was a situation that I overthought
