Many busy businesses utilize auto attendant greetings to make a great first impression, however, if your business relies on the personal touch of a live receptionist, it is important to have a plan in place when that position is unstaffed. Make sure your voicemail greeting contains the useful information that your receptionist would normally provide. This could include: location & directions, office hours, website URL, or social media info, as well as any pertinent company information.
7.) End on a high note! You don’t necessarily need to say “Goodbye” at the end of a voicemail, because you didn’t really talk to anyone. Instead, try something like, “Look forward to chatting with you!” Use the word “with” instead of “to.” It sounds less like the person is going to receive a parental or boss “talking to” and more like two people who are eager to connect with one another on the phone. It’s a subtle difference, yet it’s a gracious one!

The longer it gets, the more likely your potential client will hang up because they are annoyed.
Voicemails need to maintain a professional consistency that’s aligned with the entity it’s representing. That said, the structure can vary depending on the situation. There’s no template set in stone. In fact, trite and generic should be off the table. The goal should be a balance of uniqueness and practicality.
