Email Deliverability Checker

Look up your domain’s live DNS records: mail servers (MX), SPF, DMARC policy and BIMI. Missing or weak records are a common reason emails go to spam — and Gmail and Yahoo now require them for bulk senders.

How it works

Live checks. No sign-up.

  1. 01Enter your email domain

What are SPF and DMARC?

SPF lists the servers allowed to send email for your domain. DMARC tells receiving servers what to do with messages that fail authentication and sends you reports. Together they protect your domain from spoofing and improve deliverability.

Why is DKIM not shown?

DKIM records are published under a selector name that only your email provider knows, so they cannot be discovered from the domain alone. We check DKIM as part of a full review.
