About the Domain Health Checker
Our domain health checker inspects a domain's email configuration and DNS records to tell you whether it is set up to send and receive mail securely. It looks at MX records, SPF, DKIM, and DMARC policies, giving you a clear picture of a domain's deliverability and anti-spoofing protection.
Misconfigured email records are one of the most common reasons legitimate messages land in spam, and missing DMARC leaves a domain open to being impersonated by scammers. Checking a domain takes seconds and helps you catch these issues before they cost you deliverability or reputation.
Enter any domain to get an instant, private report. Use it to audit your own domain, or to vet a domain you have received suspicious mail from.
Frequently asked questions
What is an MX record?
An MX (Mail Exchange) record tells the internet which servers are responsible for receiving email for a domain. Without a valid MX record, a domain cannot receive mail.
Why does my domain need DMARC?
DMARC prevents attackers from impersonating your domain in phishing emails. It tells receiving servers to reject or quarantine messages that fail authentication, protecting your brand and recipients.
Why are my emails going to spam?
Common causes include missing or misconfigured SPF, DKIM, or DMARC records, a poor sending reputation, or being listed on a blacklist. This checker helps you spot the configuration issues quickly.
