To whom it may concern,
I am not one to be offended and this email certainly does not offend me, but I find it in extremely bad taste. 

Even though this is irrelevant to this discussion, I had a great father who I miss every day since he passed from this life. I am also a father and my wife and I have been married for 34 years and we raised 3 wonderful, critical thinking children.
 
Apparently whoever presented this idea to your management, and subsequently, the person or persons who approved this message are not exercising their critical thinking skills. 

I did not receive a similar email from you, asking me if I wanted to opt out of Mother's Day emails. I understand there are probably more people with bad fathers vs. bad mothers, but I know for a fact there are plenty of bad mothers out there and probably quite a few people who do not celebrate Mother's day.
 
Instead of targeting a specific group, why not ask if someone wants to opt out of all "Holiday" emails? That would have been so much better. 

Or provide a list of holidays that the person would like to receive emails regarding on their profile. 

It is better to try to unite people than to divide them. Emails like this do nothing but contribute to division.

You should know better than this.
