Email Domain Checker
Verify a domain's email configuration — MX records, SPF, DKIM, and DMARC in one click.
What Does This Tool Check?
MX Records tell mail servers where to deliver email for a domain. Without valid MX records, a domain cannot receive email. SPF (Sender Policy Framework) specifies which servers are authorized to send email for a domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature to verify message integrity. DMARC (Domain-based Message Authentication) tells receiving servers how to handle messages that fail SPF or DKIM checks.
Why Check Domain Email Configuration?
Misconfigured email authentication leads to deliverability problems, spoofing vulnerabilities, and emails landing in spam. Use this tool to audit any domain's email setup before sending campaigns or to verify your own configuration.
