Enterprise-grade email validation for founders. Check any address in 50 ms with 97.3 % accuracy. Pay-as-you-go from $0.0003/email—first 500 checks free. Stop overpaying for bounces. Launch day: win 1 M credits!
After launching Released, our AI assistant for vacation rental hosts, we ran into a big problem: email bounces.
we needed to validate emails fast, accurately, and affordably, but most tools were overpriced, clunky, or just didn’t work well enough.
So we built Lero, a blazing fast, accurate, and affordable email validator made specifically for founders who want clean lists without blowing their budget.
