Verify Your Email Authentication
The DMARC and SPF Checker provides a comprehensive analysis of your domain's email authentication policies. It automatically retrieves and evaluates your TXT records to identify critical configurations such as SPF alignment, DKIM status, and DMARC policies like none, quarantine, or reject. By identifying these settings, you can ensure that your emails reach the inbox while protecting your brand from spoofing attempts and unauthorized use of your domain in phishing campaigns.
Secure Data Handling
Privacy is a core priority for our tools. The DNS query (TXT records) runs directly from the browser via DNS-over-HTTPS against the public Cloudflare resolver – not through our server. This means that your specific domain queries are never processed or stored by aiotool.de, providing you with a direct and private way to verify your email authentication settings without unnecessary middleman involvement or risk of data exposure.
Frequently asked questions
What is an SPF record?
An SPF (Sender Policy Framework) record specifies which mail servers are authorized to send emails on behalf of your domain. By checking this, you can prevent unauthorized servers from sending emails using your identity, which helps improve overall email deliverability and protects against common phishing tactics.
What does a DMARC policy do?
A DMARC policy tells receiving mail servers what to do if an email fails SPF or DKIM checks. The options include none (no action), quarantine (send to spam folder), and reject (block the email entirely). Choosing the right policy is essential for protecting your brand's reputation.
Why should I check my DMARC and SPF records?
By analyzing these records, you can identify configuration errors that might cause your emails to be flagged as spam or blocked. Proper alignment ensures that mail servers can verify your identity, leading to higher inbox placement and better communication reliability for your business.
Is my data safe when using this tool?
Yes, your privacy is protected. The DNS query (TXT records) runs directly from the browser via DNS-over-HTTPS against the public Cloudflare resolver – not through our server. This ensures that your specific queries are processed by a trusted provider rather than being stored on our platform.
