All companies should have professional voicemail greetings. It’s important that all voicemails are professionally-read and sound consistent across each department. This provides the caller with an elevated experience, setting them up for success on every customer interaction.
Your phone system can be a powerful marketing tool for your business, and that includes your voicemail greeting. If you want to utilize this opportunity to throw in a quick humblebrag and keep callers informed of your awards and accolades, there are a few best practices, you should follow. First, keep the self-promotion brief and appropriately placed within your voicemail message. Don’t promote yourself and your products/services in the same greeting, and finally, only include current achievements in your business voicemail greeting.

It is really important to strike a balance between coming off as too cold, conservative and impersonal with making your message too out there, long or eccentric. If you can create something memorable, it will help engage a caller, or potential client. Go too far off the deep end, and you’ll scare them away
