Lemlist Voice Cloning Revolution: How AI Voice Messages Are Transforming Email Marketing in 2025
Voice notes are getting 2x higher reply rates than text messages on LinkedIn, but most sales teams avoid them because manual recording is time-consuming. That changed in May 2025 when Lemlist integrated ElevenLabs voice cloning technology, revolutionizing outreach forever.

- Mention recent posts or achievements
- Reference mutual connections
- Include location-specific details

When to Deploy AI Voice Messages
Strategic timing maximizes impact:
