Timing is everything. The moment you receive the lead alert is the best time to make the follow-up call. If you call them days later, your chances of getting them on the phone are greatly diminished. By calling them right away, you’ll talk to more leads which will inevitably boosts sales. Role-play your voicemail scripts so you sound like you’re making your 20th call, not your 1st. Ask your friends and colleagues for honest feedback on your voicemail scripts. Continually review what’s working and what isn’t -- there’s always room for improvement. If you have the lead’s email address, follow up with an email, and let them know in the voicemail you’re going to do so. If you don’t have an email, let them know you’ll follow up with a text.
There is no definitive answer here, but you should include one of the two at the beginning of your message based on what makes the most sense.

Voicemails don’t necessarily have to be monotonous or extremely jazzy or funky. What you should be looking for is a balance between the two. Whenever you call someone and their voicemail greeting is playing, it tells you a lot about who they are, as a person. Which is why, you’ve got to put a little bit of “you” when it comes to voicemail. And the best part about all of this is, since you couldn’t come to the phone, at least the callers are having a good time listening to the message.
Voicemail greetings are simple things, and in a business, they can seem unimportant. However, a voice mail greeting gets a lot of play with customers and associates—think of how often you are unable to take a phone call because you're on another line, away from your desk or out of the office.
