I got an e-mail about the World Health Care Congress (WHCC) which made me wonder why people miss some of the simplest stuff in communications. As you can see in the picture below, they were re-using a message but instead of replacing my name, they crossed out the other name.
And, to make it worse, they use the acroynm WHC instead of WHCC which is the one used by the conference. Simple mistakes that give a lack of credibility to the message.
