How to leave a cold call voicemail
A voicemail rarely earns a callback on its own, so pair it with an email that arrives moments later.
Short, specific, and paired is the formula.
Short answer
To leave an effective cold call voicemail, keep it under 20 seconds, state your name and number slowly, give one specific reason for the call, and mention you will follow up by email. Treat the voicemail as one half of a voicemail-plus-email combo, since together they roughly double response rates.
Step by step
Keep it under 20 seconds
Long voicemails get deleted before they finish. A short, specific message respects the prospect's time and gets heard.
State your name and number slowly
Say your number clearly, ideally twice. If they cannot catch it, they cannot call back even if they want to.
Give one specific reason
Name a single relevant reason for the call tied to their world. Specificity is what makes a voicemail worth a response.
Point to your email
Mention you will follow up by email with the details. The email carries the substance the short voicemail cannot.
Send the paired email immediately
Email within minutes, referencing the voicemail ("just left you a voicemail"). The combo roughly doubles your response odds.

Frequently asked questions
Should I leave a voicemail on a cold call?
Yes, as part of a voicemail-plus-email combo. On its own a voicemail rarely earns a callback, but paired with an immediate email it reinforces your name and reason and roughly doubles your response odds.
How long should a cold call voicemail be?
Under 20 seconds. A short, specific message that names one reason and points to an email respects the prospect's time and gets heard, while a long voicemail gets deleted before it finishes.
Why pair a voicemail with an email?
Because most people ignore voicemail but scan email. An email sent right after the voicemail reaches the prospect in the channel they check, connects the two touches, and lifts your response rate substantially.
