When you create a professional voicemail greeting, it can be a good idea to think about what your callers might want to know. After doing so, you can make a list of points to cover in your voice message; it might also be a good idea to write out the entire greeting on a piece of paper. The ideal message should be somewhere between 10 and 20 seconds, so you may want to time yourself repeating your message before you record it. After composing your telephone message, it can be a good idea to get a second opinion of this greeting so you can make sure it sounds professional. Writing down a voicemail greeting helps prevent mistakes when recording it.
12. “Hello, you’ve reached the Customer Support department at [company name]. We are unable to take your call at the moment. We know your time is valuable so instead of placing you on hold, let us call you back! Please leave your name, phone number, the reason for your call, and two different times that are convenient for you to receive a call back from us. Thank you!” Get a better idea of your caller’s schedule by asking them for a few different times you can call back. Their time is important, too!

Noise in the background of a voicemail is both unprofessional and distracting. Background noise can communicate to the receiver that you are inconsiderate and have not taken the time to prepare and assess your surroundings. Make sure you are situated in a quiet environment when leaving a voicemail to ensure that your message is clearly heard.
Cell phone voicemail greetings are generally more personal and casual than office phones. Consider a greeting like “Hello, you’ve reached [your name]’s cell phone. I can’t take your call at the moment, but if you leave a brief message, I’ll get back to you as quickly as possible.”
