State your name first. You would think this would be so basic that it shouldn’t even be mentioned. However, I can’t count the number of times I’ve gotten voicemails where people go on and on and I don’t even know who’s talking to me until the very end. Pretty annoying.
The process of using a voicemail greeting recorded by a professional voice talent is somewhat easier. You'll still want to review your current message and write your script, but you can submit your script to be recorded and edited and upload the file to your phone system when it's finished.

Don’t give up when you don’t receive a call from lead you’ve reached out to. You will need to make at least a handful of calls, plus emails and texts, over the next couple of weeks to maximize your chances of speaking to the lead. You may find that leads don’t want to speak directly to you but will communicate through text or email. No matter the avenue of conversation, consider it a win when they start conversing with you through any form of communication. Be persistent. If you don’t hear from them after weeks of effort, nurture them through a drip email campaign. All of the effort you put forth to reach out to the lead may not result in an immediate response but, they may call you in six months and that is a win.
