😬Why Look Beyond Lemlist's Email Verifier?
Lemlist is great for cold outreach automation.
But its email verifier is… basic.
❌ Limited validation layers
mostly syntax + MX
❌ No dedicated API
limited integration options
❌ No bulk upload optimization
slow for large lists
❌ Hidden pricing structure
unclear costs
If your lists are large, dirty, or coming from lead magnets, you need something stronger.
