The annoyance is at myself.

I take full responsibility.
I got an email about a job application and I was so eager to respond quickly, I didn't think it through and assumed the name Emer was a man, so I addressed it 'Mr xxx'.

Hit send and THEN realised it
might be female.... I can't find the specific person online, but it does seem it's a female (Irish) name.

Hoping it's forgivable since it's not a common name, but I'm still kicking myself.
