We landed Top 16—huge thanks, PH fam! 🎉 (+ new referral perks)

Hey Hunters ,

Last Thursday was nothing short of madness - in the best possible way. Lero debuted, and with your votes & feedback we finished Top 16 Product of the Day. Couldn t have scripted it better for a first launch.

What s new since the launch?

Founders, drop your 1 email-marketing tactic - let’s build a playbook together 🚀

Hey PH & Lero fam ,

Quick back-story:

Lero was born because my first startup kept face-planting on launch day - half our emails bounced into the void. I hacked together a tiny validator to fix that pain, the tool snowballed, and here we are.

Lero – Email Validator Pros: Lero provides a straightforward solution for validating email addresses, with support for both single checks and bulk uploads. It offers an API for integration into existing systems and operates on a pay-as-you-go pricing model, which can be cost-effective for teams with variable usage. The platform emphasizes fast processing times and data security, including GDPR compliance and hosting on ISO 27001-certified infrastructure. Cons: As a newer product, long-term performance and scalability in high-volume environments remain to be fully demonstrated.

Hey Product Hunt!

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.

  • 50 ms validation speed

  • 97.3% accuracy

  • From $0.0003/email — pay-as-you-go

  • First 500 emails free

  • Protect your sender reputation

  • Clean lists = higher conversions, fewer bounces

Special for Product Hunt:🎟️ We’re giving away 1,000,000 free credits to a user who signs up today💥

Use code PHFAM to validate 10,000 emails for just $0.99

Lero started as a tool I built to solve my own pain. Now it’s here to help other founders avoid the same trap.

Try it out and let me know what you think.

It’s still early days — We know it’s not perfect yet. But we’re fully committed to making it better every single day.

Built by founders, for founders.👉 Visit Lero

Lero's fast validation speed and affordable pricing are a huge relief for founders dealing with email bounces! For users with large email lists, does Lero have any plans to offer bulk validation discounts or more advanced list management features?

@yongxiang_wang Appreciate that, Evan, totally hear you. Bulk validation pricing is on the roadmap, along with smarter list cleanup and auto-tagging tools. We’re building towards a flow where Lero doesn’t just validate, it helps you act on the data. Super grateful for your input 🙏
