Revalidate.ai: Real-time email verification that cuts bounces

Hey Product Hunt! 👋 I'm Srikanth, founder of Revalidate.ai. Like many of you, I kept seeing the same painful problem: teams sending campaigns to lists full of dead, fake and risky addresses. The issue usually isn't the message. It's that the bounces damage your sender reputation, and then even your good emails start landing in spam. So I built Revalidate.ai, a tool that verifies email addresses in real time, so you can clean a list before you send instead of finding out from your bounce rate. Upload a CSV or paste a single address, and it checks each one and tells you which are safe to send to. What I'm most proud of: Deep verification in 3 steps. Upload, verify, download a clean list. It checks syntax and typos, DNS/MX records, disposable and role-based addresses, and does a live SMTP check. No emails sent to your contacts. The SMTP check verifies the mailbox without sending a message, so your subscribers never know. Free to start. 100 free Basic checks every month, no credit card, so you can try it on a real list before deciding. Paid plans are one-time credit packs from $5, with no subscription and credits that never expire. I'm honest about what it does: no verifier can guarantee a zero bounce rate, and some servers (catch-all domains, greylisting) can't be fully confirmed. Revalidate.ai handles those cases and gives you a confidence score, so you can decide what to send to. Free to start. I'd love to hear what you'd want from an email verifier, and I'm online all day to reply to every comment.
