When it comes to media relations and corporate communications, PR pros should follow AP Style
Anytime you communicate with a client or customer, you make an impression on behalf of your company. You want to represent professionalism and quality of content, and your written communications are simple ways to do that.
Spelling and grammar mistakes make your company look unprofessional, sloppy, and uninterested. If you don’t ensure all your written communications are error-free, it looks like your company didn’t put forth the time and effort to produce its very best work. Clear, consistent copy editing improves your company’s corporate communications.
