I am not a voice talent, and I hate the sound of my own voice. Every time I lose my cell phone (daily), I call it from another line to help myself find it. And every time I do this, I wish my voicemail message sounded…different. I’m always reminded that I should sit down and rerecord it, so it makes a more professional first impression.
21. Hello, this is [your name]. I’m not much of a phone person, so don’t bother leaving a message. Send me an email at [email address] and I’ll get back to you within 24 hours.

Consider for a moment how your phone is currently being answered. Professional courtesy is quite often not the standard for many college students. An abrupt "Yeah!" could be listed among the more courteous greetings. The more outrageous remarks will often buy you a major black mark in the professionalism category—even if it was your roommate answering your phone and acting crazy. A simple "This is ____" is always a pleasant change for a college student call. Make the change today, before the next (or first) employer phone call. If you have a landline, you should also encourage your roommate to do the same.
It is, therefore, kind and polite to reassure them that they have reached the right person by stating your name or company name at the start of the message.
