Checks SPF/DKIM/DMARC/PTR/MX DNS records with health scoring, verifies addresses via SMTP RCPT TO with bind-IP support, detects role-based emails (admin@, support@), corrects domain typos (gmial.com -> gmail.com), scans 29 RBL blacklists, and flags disposable email domains (~74k). Includes REST API. Free demo: https://probe.uspeedo.online/
