Arguably the most intimidating factor when leaving a voice mail is the fact that once you leave the message, "in one take," there is no taking it back. That is why, especially in the business world, an overwhelming amount of people revert to email rather than leaving a voice mail message. Especially in a technologically advanced world, email or text messages are now used as a primary form of communication. Although there is a good argument behind opting for the written word over the spoken one, an email can lack the human touch, the emotion and enthusiasm in a voice, that can often times generate a better response. In fact, there is no impact that compares to delivering a clear, concise, professional message through your own unique human voice.
Many messaging apps now offer the ability to send voice messages to contacts without having to make a phone call in the first place. Using this method, you're bypassing a phone call and voicemail entirely, but it serves the same purpose.

Voicemails Forever is like an answer to a prayer! I have saved these voice messages from my daughter since 2008. Glad to know that now I can have them stored safely. Pamela T Drake
A word of warning: These greetings will not do you any favors if you're in the midst of a job hunt or work in a conservative industry. Always remember your target personas. If there's a chance they won't appreciate your sense of humor, opt for a straightforward greeting instead.
