You should also research other people in the prospect’s organization. Selecting the right people, such as the prospect’s manager or department head, facilitates the ability to build rapport and adds a sense of urgency when you mention them in the voicemail.
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.

In sales, immediate communication with your prospects and current customers is important. Being available to answer questions or further negotiate a deal allows your clients to feel secure and more apt to purchase from you. But what if you can’t answer the phone when they call? Make sure you have a voicemail system set up so your clients have the opportunity to leave you a message.
If you really mean it, say you will return the call as soon as possible. For example, "This is Mary Mitchell. Please leave a message and I will call you back as soon as I can." If you want to give another option to reach you, go ahead, but limit it only to one telephone number or email address.
