Revalidate.ai

Revalidate.ai is an email verification platform that helps you remove invalid, disposable and risky addresses before you hit send, so fewer campaigns bounce and your sender reputation stays healthy. The problem: high bounce rates damage your domain reputation and push future emails into spam folders. Most lists decay over time, and even a single typo or fake signup can hurt. What Revalidate.ai does: Single check: paste one address and get an instant result. Bulk validation: upload a CSV, watch live progress, and download a detailed report. List cleaning: sort an already-validated list into clean segments and download the result. Deep checks: syntax and typo detection, DNS/MX record verification, disposable-domain detection, role-account detection (info@, admin@), and live SMTP pings that verify the mailbox without sending any email. Full Deep AI mode: goes beyond a basic handshake, with catch-all detection, retries for servers that greylist, and a confidence score for each result. Pricing: start free, no credit card needed. Paid plans are one-time credit packs from $5 for 500 credits up to $200 for 100,000, with no subscription and credits that never expire. Built for marketers, agencies, founders and sales teams who want to clean a list or check a single lead before outreach.
