The above section details types of phrasing to avoid; however, it doesn’t detail what users should NOT say on their greeting. Though this is a bit loaded, as there are hundreds of combinations of things one shouldn’t say, there are some key components users should ALWAYS avoid. a. Forget About Slang: You should strive to be as professional and welcoming as possible in your greeting. While this may steer you towards using slang, in an attempt to make callers comfortable, it’ll most likely work against you. As a professional, your demeanor, tone, and speech should be clear cut and well articulated. Using slang undercuts this and works against you. b. Don’t Even Think About Profanity: This is a no-brainer. Never, under any circumstances, curse in your greeting EVER! c. Keep Your Sentences Clean, Don’t Ramble: Introduce yourself and give your caller specific direction. Avoid long diatribes detailing tangent thoughts. Keep it simple and quick. d. Always Return Your Calls: It’s important for callers to feel they are valued. Nothing dissolves this quicker than a greeting that doesn’t stress this. For example, “I’ll call you when I can,” “If I don’t return your call, please call back”—these phrases are terrible and completely destroy any good will you may have with a caller.
Professional — Lets them know who they’ve reached, why their call has not been answered and when they can expect a return call.Personable — Lets them know their message has been received by a real person who values their call and will reach back out to them. Including humor and a personal touch is extremely important here (even if your industry prefers to be more “robotic” in their communications). What is the most professional voicemail message?

18. “Thanks for calling [Company name/your name]. We hope you’re enjoying the holiday season. We aren’t available at the moment due to our holiday hours. Leave your name, number and the reason for your call and we’ll get back to you ASAP! Thanks for calling.” Everyone deserves a break. Let your callers know although you might be enjoying one too, that their needs are important.
It's as much a truth with residential phone service as it is with business communications, though those numbers are much lower. Voice over Internet Protocol (VoIP) phone service provider Vonage reported in April that voicemail deposits among its residential customers had dropped by 8 percent since October 2013, and retrieved messages were down 14 percent.
