The average voicemail response rate is only 4.8% according to statistics. So what makes those few voicemails stand out from the crowd to get a response while others go totally bust?
Users often don’t invest enough time into their messages, resulting in incomplete, unprofessional, or otherwise under-whelming greetings. Sure, crafting a greeting doesn’t sound all that complicated; however, there are a number of pitfalls users can fall into—i.e. informality, terseness, sincerity, lack of direction, and more. While none of these sound too catastrophic, they are often interrelated. As such, they tend to worsen any problem. For example, humor can cause informality, worsen ambiguity, and weaken sincerity. That being said, users should strive to avoid ALL these pitfalls.

The most important aspect of a voicemail message is that the listener must be able to understand your message. Don’t mumble your words and be sure to speak loudly and clearly. Speaking softly will make it difficult to understand you and may result in the listener not being able to call you back.
