LeadTailor.AI increases cold outreach conversion using ElevenLabs

Personalized outreach at scale

LeadTailor.AI is rethinking sales outreach. Their platform enables users to send highly personalized prospecting videos—each one voiced by ElevenLabs. What used to be static cold emails are now dynamic, human-sounding pitches that capture attention and drive results.

To ensure each video sounds natural, LeadTailor needed the most realistic AI voice model available. ElevenLabs was the clear choice.

Today, LeadTailor uses ElevenLabs to generate high-quality AI voices for every prospecting video—making outreach feel like a real conversation.

More than 10x conversion with natural-sounding voices

LeadTailor’s outreach metrics are outperforming industry benchmarks by more than 10x:

“We engage around 40% of our prospects and convert 10–25% of outreach into meetings. Typical cold outreach converts under 1%. These results are powered by ElevenLabs. If the voices weren’t good, we wouldn’t see conversion rates like this.”

— Amir Andraws, Co-Founder of LeadTailor.AI

Prospects frequently praise the voices for how real and natural they sound. One customer shared:

“We’re thoroughly impressed with the platform’s capabilities and the value it brings to our outreach efforts. It’s truly a game-changer.”

Scaling rapidly with human-level quality

LeadTailor started with two voices and has expanded to eight. They’re now integrating voice cloning via our API, enabling customers to send videos in their own voice—with just a few clicks.

“We consistently hear how amazed people are by the voice quality,” Amir says. “It’s a key reason we’ve onboarded 40 customers in just a month. ElevenLabs has been a game-changer. Their AI-generated voices bring a level of realism and personalization that enhances engagement with every video we send.”
