I like to say my phone number very early so the person can hear it again quickly by starting the message over and does not have to listen to your entire message again to hear the number. But do repeat your telephone number at the end of the message at least once and speak very s-l-o-w-l-y so the person can write it down as they listen. If you don't get a response to your first voicemail, don't hesitate to record a similar message once a week for two or three weeks. This sounds a bit excessive, but my experience has been that if there is even the slightest chance of meeting someone now or even in the near future, this kind of message will get their attention.
Good professional voicemail greeting examples. A business named Lorem Ipsum, which sells widgets, wants to leave a brief message that confirms for the listener that they have called the right business. The message would also prompt the caller to provide information needed to return the call, and throws in a nice quick promotional note.

These days, most phone functions are for tweeting and texting, but what about leaving voicemail messages that get returned? Many people say they no longer check voicemail, or don’t listen to messages in full. They either tap “return call,” send a text, or find other channels to see what the person wanted.
Be sure to include all important details, like why you are calling, your contact number, your name and anything else that’s necessary. If you are following up a previous voicemail, say so. If you had been confusing in the previous voicemail, apologize and proceed with your message.
