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.
You can’t always get to the phone when clients, partners, investors, or colleagues call you. When this happens, a professional voicemail greeting helps you make a positive impression and tells them what to do next. There are a variety of ways to convey your message. If you’re not sure what type of message to record for your own voicemail box, here’s a definitive guide to get you started.

Keep in mind that short greetings are often much better then trying to say way too much that could confuse your callers. Some pointers to ask, “please leave your name and number”, or maybe ask them to go your business website to contact you by email, or even as simple as text.
Your second call should happen immediately after your first voicemail. In this message, quickly say, in 10 seconds or less, an important detail you neglected to mention during your first call.
