You call into a business. While you wait to get to the right person, you listen to music, information about the company and its promotions, or maybe even a recording that reminds you that your call is important to them. Most business-class phone systems come with a library of pre-recorded on-hold messages or music for you to choose from.
Conducting extra research on your prospects before you call them is always a good idea. This script from Mike Brooks is a great example of how you can use this additional information in your sales voicemails.

Email to Group: If you are writing an email to two to five individuals, use both names in your salutation. For example Dear Mr. Jake and Miss Jones. This is acceptable in a professional mail. Unknown Gender: If you don’t know the recipient’s gender, use both the first name and the last name instead of the title case.
Using your carrier’s standard voice messaging procedure to save these messages can be a pain in the butt! Although, if you have an iPhone, you can use the phone’s voicemail app to store your messages via iTunes to your computer, but the audio files are stored in unreadable configuration which requires some skills to understand.
