Don’t rush. It’s important to speak slowly and clearly when leaving your next voicemail greeting. Have you ever called someone and the message sounds like one big word? Don’t be that guy. Pronounce your words and take pauses between your sentences
Funny, the majority of us have a phone on us more hours of the day than not, but actually we’re harder to talk to than ever. On personal calls, and especially business calls, you’re much more likely to reach voicemail than the actual person you’re hoping to engage in conversation.

Because you never know the quality of someone’s phone audio or your cell phone service, it's not a bad idea to give your name and phone number twice within your message. The thought being, if the person you called can’t understand who you are or how to call you back, how can they be expected to return your call?
The next morning you realize the mistake you’ve made and pray she hasn’t opened it yet. You search the internet and ask your peers how to delete voicemails from someone else’s voicemail box – but it’s too late.
