How LinkedIn Voice Messages Increased Replies by 40%: A Data-Backed Strategy

80% of LinkedIn users ignore cold InMails—here’s how voice messages break through and boost lead generation.

Tired of sending cold LinkedIn messages that get ignored? You’re not alone. With inboxes flooded daily, text-based outreach no longer stands out. But what does? LinkedIn voice messages.

Data shows that adding voice messages to your LinkedIn strategy can increase response rates by up to 40%—turning ignored messages into active conversations.

Timpl, a top staffing firm, leveraged LinkedIn voice messages to humanize their outreach and accelerate placements. Here’s exactly how they did it—and how you can apply the same approach.

Why LinkedIn Voice Messages Work (And Outperform Text)

A Voice = Instant Trust

Text messages sound robotic. A voice note? It’s personal, engaging, and builds credibility in seconds.

Higher Engagement Rates

Prospects see effort when you take time to record a message. This creates a natural obligation to reply.

Faster & More Convenient

A 45-second voice note delivers 3X more information than a paragraph of text. Recipients can listen while multitasking.

Timpl tested this strategy and saw a 30% faster response rate—why? Because candidates and hiring managers felt a real human connection.

The 4-Step LinkedIn Voice Messaging Playbook

1. Optimize Before You Send

Before hitting record, ensure your LinkedIn profile is investor-ready:
✔️ Professional headline showcasing your expertise.
✔️ Clear summary with a direct value proposition.
✔️ Recent activity to signal industry engagement.

2. Target the Right Leads

Not every LinkedIn user is the right fit. Use LinkedIn Sales Navigator to filter prospects by:
✔️ Job title (e.g., HR Directors, Hiring Managers)
✔️ Industry (e.g., Tech, Healthcare, Finance)
✔️ Engagement (e.g., Active posters, recent promotions)

Timpl focused exclusively on decision-makers in hiring, ensuring every voice message went to the right person.

3. The Perfect LinkedIn Voice Message Formula

Keep it Under 45 Seconds – The shorter, the better.

Follow This Simple Script:

Greetings: “Hey [First Name], this is [Your Name] from [Company].”

Personalized Hook: “I saw your post about [topic] and wanted to share something useful.”

Value Pitch: “We recently helped [Company X] speed up hiring by 35%—thought you’d find this interesting.”

Soft Call to Action: “Would love your thoughts—open to a quick chat?”

Timpl’s recruiters followed this structure and immediately saw a 25% boost in responses.

4. Follow Up With Text for Maximum Impact

Send a text recap after your voice note. Some prospects prefer to skim before responding.

Mention a shared connection or mutual interest. Example: “By the way, I noticed we both follow [Industry Leader]—big fan of their work too.”

Track responses and refine. If a voice note gets ignored, tweak your hook, timing, or CTA.

Real Results: How Timpl Used Voice Messages to Dominate LinkedIn Recruiting

Before voice messaging, Timpl struggled with low engagement on LinkedIn InMails. But after incorporating voice messages into their outreach, they saw:

40% increase in response rates.
50% faster conversations with hiring managers.
⏳ Less time wasted on cold outreach—more warm leads.

Their secret? A personalized, voice-driven approach that felt human, not salesy.
