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.

You might call this one a sign of Potomac Fever. To the tune of "Hail to the Chief": "We are not in the Oval Office at this time. We will, to the best of our abilities, faithfully execute the task of calling you back, so help us God."
The way all your words and sentences come together gives your script a distinct written tone. Combine that with a specific speaking tone to create an on-hold message that reinforces your brand and product set. Selecting the correct tones will ensure your intended message is communicated effectively. If your target market is the younger generation, then a tone which embodies fun and excitement would be most suitable.
