The truth is, you can’t delete a voicemail from someone else’s voicemail box once you have recorded it and hung up. So whatever you need to do has to be done BEFORE hanging up. Here’s how you can save yourself from those accidental voicemails that you wish you had never sent in the first place.
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.

So, leave "Call me back when you get this," at the door, and try, "Talk to you soon," "Thanks for your time," or a good old-fashioned, "Have a great day."
