"Congrats, you survived the Boston Marathon." So reads the subject line of an email sent to marathon participants by Adidas on Tuesday, USA Today reports. This was, for obvious reasons, a poor choice of subject line. And according to the New York Daily News, recipients of the email didn't waste any time sharing screenshots of it on social media and letting Adidas know. The company quickly apologized for the email. "Clearly, there was no thought given to the insensitive email subject line we sent Tuesday," Business Insider quotes Adidas spokesperson Maria Culp as saying in a statement. Culp says the company is "incredibly sorry." Three people were killed and 264 injured in the Boston Marathon bombing four years ago. (More Boston Marathon bombing stories.)
