I'm going to office and maintaining 85% attendance but today I got this mail from HR , don't know why?

This is my suggestion, try to give them their own medicine. Reply on the same mail, hi, I have been having family issues because my my next of kin is having so on so issues, (make something health issues), but still I don't let my personal and professional work separate and trying my best to attend the office, and inthe last quarter I have clockex 86% wfo, and as per my manager/director i have been compliant with maintaining 85% min attendance.

Only thing could be minimum average hours, if you are maintaining 85%

Check the sender email properly, I received the phishing mail last time from my manager's I'd with slight changes in email
