Free Domain Checker
Check any domain's SPF, DKIM, and DMARC records in seconds so your emails reach the inbox instead of spam. Free domain checker — plus done-for-you setup for $500.
If your business emails keep landing in spam, the problem usually is not your message — it is your domain's email authentication. Our free domain checker looks up any domain's SPF, DKIM, and DMARC records in seconds and tells you in plain English whether they are set up correctly.
Good deliverability is the foundation of every follow-up, quote, and appointment reminder you send. Run your domain now, see exactly what is missing, and either fix it yourself or let our Dallas-based team handle it for you.
Check SPF, DKIM, and DMARC Records Free
Enter any domain and instantly see whether its SPF, DKIM, and DMARC email authentication records exist and are configured correctly. The checker reads your live DNS records the same way Gmail, Outlook, and Yahoo do, then flags anything that is missing, duplicated, or malformed. There is no signup and no limit on how many domains you can look up.
Why Your Emails Go to Spam
Missing or broken email authentication is the number one reason business email lands in spam folders instead of the inbox. When a mailbox provider cannot verify that a message really came from your domain, it treats it as suspicious and quietly filters it out. That means your quotes, invoices, and follow-up messages may never be seen, even by customers who genuinely want to hear from you.
What SPF, DKIM, and DMARC Actually Do
These three DNS records work together to prove your identity to receiving mail servers. SPF lists which servers are allowed to send on your behalf, DKIM adds a cryptographic signature that confirms the message was not tampered with, and DMARC tells providers what to do when a message fails those checks. Together they protect your deliverability and stop scammers from spoofing your brand.
Fix Email Deliverability Problems
Once the checker highlights what is wrong, you get specific, actionable results rather than a vague pass or fail. You will see whether an SPF record is missing an include, whether DKIM keys are published, and whether DMARC has a policy set. Hand the results to your IT provider or update the records yourself, and most deliverability issues can be resolved in a few minutes.
