If done tastefully, you can promote your products or services on your voicemail greeting without sounding pushy. In fact, it’s a great way to keep customers up-to-date on company events, sales, and other news. Be sure to keep it short and have fun with it.
For example, a message like, “Hi, this is Jim. You know what to do.” Well, not everyone is going to know what to do—i.e. they won’t leave you inclusive information. Additionally, they may not leave you a message at all. Aside from this, humor can again be detrimental to your message, this time lending itself to ambiguity and costing you clarity. For example, if a message read, “Hi this is Jim, sorry I can’t answer your call right now. Please leave your name and number and I’ll call you as soon as I can, but you already knew that right? Do I need to tell you what to do?” This is worse than the previous example as this is confusing and can also come across as rude and unprofessional. Complicating a greeting with phrasing like this is sure to cause some harm. e. Ignoring Personality & Identity: Don’t use computer generated greetings. Some users leave default messages (‘you’ve reached the voicemail box of 777-777-777, please leave a message). Believe it or not, even this can cause problems. Callers may be unsure if the voicemail box belongs to you; therefore, they don’t leave a message. Also, some may even be uncomfortable leaving information through a message in a nameless voice message box. As such, impersonalization can cause ambiguity, which again can hurt the effectiveness of your voice message system. This doesn’t mean you have to make an elaborate greeting if you don’t want to, just insert your voice and name so at least callers know they’re calling the right person.

As in the situation above, a full mailbox can be really frustrating for an employer who is trying to get in touch with you. Set aside time at least once a week to make sure you clean out your voicemail. You want to be as accessible as possible for potential employers. I’ve called a few job seekers lately to help with their search and have gotten this message, “We’re sorry. The person you are trying to reach has not yet set up their voicemail system. Please try again later.” This makes you look a little lazy and can frustrate the hiring managers. As soon as you get a new phone, make sure you make it a priority to get your voicemail up and running. Definitely make sure you have it set up before you start sending out job applications. I understand this could slip your mind, but it’s important that you do everything you can to show the hiring manager that you are reliable and reachable.
