Up to 90% of security breaches start with phishing emails ## Check Your DMARC Record Enter your domain to analyze your DMARC configuration and get actionable insights. Check DMARC ## What is a DMARC Record? A DMARC (Domain-based Message Authentication, Reporting & Conformance) record is a DNS entry that instructs receiving mail servers on how to handle emails that don't pass SPF or DKIM authentication checks. Think of it as a digital bouncer - ensuring only legitimate emails make it to your recipients' inboxes. Without a DMARC record, anyone could impersonate your domain and send malicious emails. DMARC ties together SPF and DKIM into a unified policy, giving you control over what happens when authentication fails and providing visibility through aggregate and forensic reports. Record Anatomy ## Components of a DMARC Record ### Version Always `v=DMARC1` Identifies this as a DMARC record. ### Policy (p=) `none` | `quarantine` | `reject` How to handle emails that fail authentication. ### Subdomain Policy (sp=) Separate policy for subdomains Optionally apply different rules to subdomains. ### Aggregate Reports (rua=) `mailto:reports@example.com` Where to send summary authentication reports. ### Forensic Reports (ruf=) `mailto:failures@example.com` Where to send detailed failure reports. ### Alignment (adkim/aspf) `s` (strict) | `r` (relaxed) How strictly DKIM/SPF domains must match the From header. Example DMARC record: `v=DMARC1; p=reject; rua=mailto:dmarc-reports@example.com; ruf=mailto:dmarc-failures@example.com; adkim=s; aspf=s;` Step by Step ## Creating Your DMARC Record 1 ### Ensure SPF and DKIM are configured DMARC builds on SPF and DKIM. Before creating a DMARC record, verify that both are properly set up for your domain. Use our [free SPF checker](/tools/spf-checker/) to validate your SPF record. 2 ### Choose a policy Start with `p=none` to monitor email traffic without affecting delivery. Once you're confident, move to `quarantine` or `reject` for full enforcement. 3 ### Define reporting addresses Set up aggregate (`rua`) and forensic (`ruf`) report destinations to gain visibility into your email authentication landscape. 4 ### Specify alignment and publish Choose strict or relaxed alignment for SPF and DKIM. Then add the record as a TXT entry at `_dmarc.yourdomain.com` in your DNS. 5 ### Verify and monitor Use a DMARC testing tool to confirm your record is published correctly. Regularly review reports and adjust your policy as you gain confidence in your authentication setup. Benefits ## Why Use a DMARC Generator? ### Eliminate Syntax Errors Generators ensure proper formatting, avoiding the misconfigurations that can silently break email authentication. ### Save Time Implementation time is reduced by up to 50% compared to manually crafting DMARC records from scratch. ### Customization Tailor policies for subdomains, set reporting preferences, and choose alignment modes to fit your organization's needs. ### Reduce Phishing by up to 99% Enforcing a `reject` policy can virtually eliminate domain impersonation in phishing attacks. ## DMARC needs SPF - and SPF needs AutoSPF DMARC alignment requires a passing SPF check. AutoSPF keeps your SPF record optimized and within the 10-lookup limit automatically.

I appreciate that it keeps a log of changes made, which prevents many mistakes. A client's SPF record would have way too many lookups, but AutoSPF makes that problem go away. The length of the SPF record is typically not the issue; it's the amount of lookups in the record that are. AutoSPF "flattens" the record, automatically expanding the defined lookups to IP addresses or ranges. And it auto-updates the record when the un-flattened lookups change. PJ Peter J. President · Small-Business (50 or fewer emp.) ### "Helped us go beyond capacity" > AutoSPF did exactly as described, it helped us get past our 10 lookup limit. Afterwards, we hit another limit regarding overall capacity and when contacted, they quickly provided us with a new solution to eliminate capacity issues entirely going forward, so now we can add as many SPF records as needed. They also provided us with a personalized support video explaining their new method in its entirety using our instance as the example. VU Verified User Financial Services · Mid-Market (51-1000 emp.)
