Lead generation and cold email for an AI Voice Agent SaaS
Hey everyone,
I recently built an AI Voice Agent SaaS using Vapi. My initial target market is medical clinics (dental, aesthetic, hair transplant, etc.) and beauty salons.
The problem I’m facing is that I’m struggling to find enough quality leads. I’ve tried scraping Google Maps and using lead databases, but the number of qualified leads is much lower than I expected.
My plan is to run cold email campaigns, but before I start sending emails at scale, I want to make sure I’m building the right lead list.
For those of you who have experience with B2B SaaS or agency lead generation:
How do you find high-quality leads consistently?
Which tools or data sources have worked best for you?
Do you rely mainly on Google Maps, Apollo, LinkedIn Sales Navigator, or something else?
How do you validate emails before sending?
What cold email strategy has produced the best reply rates for you?
I’d really appreciate hearing what’s actually working in 2026, especially from people selling to local businesses or clinics.
Thanks!
