A voicemail should rarely be a standalone activity

A Low-Friction Call to Action (CTA): This should be easy for them to complete. The goal is not to close a sale, but to prompt a response or encourage them to check out a resource.
"If that's a priority for you, please give me a call back at [Your Phone Number]."
"Alternatively, I'll send a brief email with some relevant information, and you can simply hit 'reply' if it looks interesting." (This is often more effective as it requires less effort from them).
"You can also find more information on how we help similar businesses at [Your Website/Specific Landing Page]."
Your Contact Information: Repeat your name and phone number clearly, and perhaps your company name again. Slow down when stating the phone number. "Again, my name is [Your Name], and you can reach me at [Your Phone Number]. That's [repeat number slowly]."
Timing and Tone: Deliver your voicemail with confidence, energy, and a genuine, helpful tone. A slight smile can translate into your voice, making you sound more approachable. Sounding rushed or rehearsed will undermine your message.

Strategic Follow-Up: It's often one touchpoint in a multi-channel phone number data outreach strategy. If you leave a voicemail, immediately follow it up with an email that references the voicemail and reiterates your value proposition. This increases your chances of getting a response. "Following up on the voicemail I just left you..."

A/B Testing: Don't be afraid to test different voicemail scripts. Track which messages result in the highest callback rates or email replies. Analytics from your CRM can help you identify which voicemails are most effective for different lead segments.

In essence, strategic voicemail utilization transforms a necessary evil of cold calling into a powerful prospecting tool. By making your voicemails concise, value-driven, and actionable, you increase the likelihood of engaging cold calling leads, ensuring that even when you don't connect live, you're still advancing your sales efforts.
