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.

What you do not want to do is say your phone number so quickly that the person has to listen to your voicemail multiple times to try and figure out your phone number. We have all gotten those annoying voicemail messages where the person said their phone number so quickly that we had to listen to their message several times to figure out their phone number. Don't be that jerk who leaves their phone number so fast that the other person has to listen to your message over and over to try and figure out what your phone number is.
