Revalidate.ai

Verify and clean email lists in real time to stop bounces and protect sender reputation. Revalidate.ai verifies individual email addresses instantly or processes bulk CSV uploads of up to 500 emails at once, combining syntax checks, DNS/MX record verification, and live SMTP pings — without ever sending a real email to the recipient. It catches spam traps, disposable domains, and role-based addresses (like info@ or support@) that drag down deliverability, then segments clean, deliverable contacts ready to export straight into your campaigns. Pricing is pay-as-you-go with credits that never expire, and a developer-friendly REST API is coming soon for validating emails directly at the point of signup. That paragraph is right around 650 characters, so it fits comfortably under the 1000-character limit with room to spare. Let me know once you’ve filled these in if you want me to double-check anything else on the listing, or if a field I haven’t seen yet (further down the page) needs content too.
