Typically, most of these services are uniform—i.e. include the same tools and features (send a script, they record it in a tone you approve, they send it as a file, you supply any feedback, etc.); however, there are some services that go above and beyond. For example, VoiceOverPro, is a single voice professional who records 30 second voicemail messages based on users’ scripts. This is standard; however, users also have options like adding music, recording up to 60 seconds (or 150 words), rush, 2-day turnaround, and even same day delivery.
Do you have a crowning achievement or hold a competitive advantage? Showcase that within your voicemail so you’ll be memorable and emphasize why working with you is an advantage. Here’s an example of a professional voicemail someone in real estate could use:

The importance of voicemail in the customer care sector has not diminished despite the arrival of newer web technologies. VoIP applications let the businesses use voicemail service with flexibility, as it is. The users need not rely on extension terminals when they use VoIP services. A strong internet connection is a prerequisite and the pre-configured phones can be used – both for calling /receiving calls and for automated custom greetings. IVR feature redirect callers to the right virtual extension where their needs can be addressed. This can be done anywhere through a web portal access and an internet connection.
e. Never Assume Anything: Phrases like “You Know What To Do,” “Sing Your Song at the Beep,” and others mentioned above are awful to leave in your greeting. For the sake of universality and comprehensiveness, NEVER assume the caller knows what to do. Lay it out clearly. f. Leave a Message: This phrase, by itself, will not do. It’s imperative for users to identify themselves in their greetings. Callers need to know they’ve reached the right person. g. Disregard Lethargy: If you’re not excited about your greeting, why would anyone else be? Never display a lack of enthusiasm in your greeting as it could turn callers off to both you and your business. h. Speak Clearly and Never Slur: Callers need to understand your every word; therefore, mumbling, slurring, and all other detractions of speech should never be recorded. d. Be Creative Without Sacrificing Quality: Callers know how voicemails work–i.e. leave a number, message, etc. While you want to be clear, it’s important not to be contrive or redundant with your message. Creativity can help users to differentiate themselves, as well as intrigue callers. While users should avoid the tropes of creativity listed above, it’s definitely good to think outside the box. That being said, scripting and practice can help users to experiment more with their greeting–ultimately allowing for more unique and creative approach. e. Speak With Diction: It’s important to present one’s self as an authority without alienating callers. As such, it’s crucial to articulate and speak with clear diction. “ if your voice recording has you stumbling over words and speaking haltingly, it does not convey confidence and competence,” states Ron Sellers of Grey Matter Research & Consulting. Remember, this greeting represents you; therefore, you want to appear collected and professional, as well as welcoming. To do this, one must carry themselves well through their recorded message. f. Account for Timeliness: Your message should be concise. No caller wants to be sitting through a rant/diatribe of redundant statements. Your greeting should flow without dragging. Inversely, one doesn’t want to be terse, either. Engage callers with a simplified approach laden with creativity. h. Account for Quality: Aside from speaking clearly, users want to eliminate any noise in the surrounding environment. The quality of the greeting is just as important as what’s being said in the greeting itself. As such, one doesn’t want to undermine a great message with poor quality. i. Courtesy, Tastefulness, & Tact: This is pretty self-explanatory and straight forward–NEVER be rude. Being light-hearted and humorous is very different from being obnoxious and/or abrasive. Again, these tools can be helpful if utilized properly, but not everyone perceives humor the same way. So play it safe. The last thing your voicemail greeting should do is offend a caller. k. Provide Options: if you’re part of a bigger company, it might be good to offer caller options. For example, allow a menu to defer callers to a colleague or co-worker in your absence. This can help show callers you care about their well being. Another option might be offering different modes of communication–i.e. email, fax, etc. In offering users diversity, contact may be much easier to maintain.
