What you get for every domain

Select any domain below to see its full deliverability profile and verify individual email addresses at that domain for free.

  • Live mailbox verification confirms whether a specific address exists and accepts mail, with no email ever sent.
  • MX records and mail server health show you which servers handle mail for the domain, their priority, and whether they respond.
  • SPF, DKIM and DMARC authentication tell you whether the domain protects against spoofing and how receivers will treat your mail.
  • Deliverability scoring and reputation give you a clear verdict: safe to send, proceed with caution, or do not send.
  • WHOIS registration and domain history reveal who operates the domain, when it was registered, and its nameservers.

Cleaning a full list?

Upload a CSV or TXT file with any number of addresses across any mix of domains. Every address runs through the same live SMTP checks you see on the individual domain pages, plus catch-all detection, role-account filtering, and disposable domain blocking.
