Generate a DMARC Record in Seconds – No Technical Expertise Required
Emailer's DMARC generator helps you protect your domain from spoofing and ensures your emails land in the inbox.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is essential for securing your email domain against phishing and spoofing attacks. A DMARC record tells receiving mail servers how to handle emails that fail authentication checks. Emailer's DMARC generator simplifies the process of creating a valid DMARC record, so you can implement email authentication quickly and correctly.

What Is a DMARC Generator?
A DMARC generator is a tool that creates a DMARC DNS record based on your domain's specific needs. Instead of manually crafting the policy string, you select your preferred policy (none, quarantine, or reject), set the reporting options, and the tool generates the exact TXT record to add to your DNS.
Using a DMARC record generator eliminates syntax errors and ensures your record follows the latest RFC standards. Emailer's generator also provides guidance on each parameter, helping you understand what each part of the record does.
Why You Need a DMARC Record
Without a DMARC record, cybercriminals can spoof your domain to send fraudulent emails that appear to come from you. This damages your brand reputation and puts your customers at risk. DMARC builds on SPF and DKIM to give you control over unauthenticated email.
Additionally, major email providers like Gmail and Yahoo require DMARC for high-volume senders. Implementing DMARC improves deliverability and ensures your legitimate emails are less likely to end up in spam folders.
How to Use the DMARC Record Generator
Start by entering your domain name. Then choose a policy: 'none' for monitoring only, 'quarantine' to send failing emails to spam, or 'reject' to block them entirely. We recommend starting with 'none' to collect data before enforcing a stricter policy.
Next, set your reporting email addresses to receive aggregate and forensic reports. These reports show which emails pass or fail authentication. Finally, click 'Generate' to get your DMARC record. Copy the TXT record and add it to your DNS provider's settings.
Best Practices for Your DMARC Record
Always start with a policy of 'p=none' and review your DMARC reports for at least a week. This helps you identify legitimate email sources you might have missed. Once you're confident, move to 'p=quarantine', then finally 'p=reject' for maximum protection.
Set a subdomain policy (sp) if you want to apply a different rule for subdomains. Use a percentage tag (pct) to gradually apply the policy to a portion of your email traffic. Regularly monitor the reports and adjust your SPF and DKIM records as needed.

FAQ
What is a DMARC record and why do I need one?
A DMARC record is a DNS TXT entry that defines how email receivers should handle messages that fail SPF or DKIM checks. It protects your domain from spoofing and improves email deliverability.
How do I create a DMARC record with Emailer?
Enter your domain, choose a policy (none, quarantine, or reject), add reporting emails, and click Generate. Copy the output and add it as a TXT record in your DNS provider.
What is the best DMARC policy to start with?
Start with 'p=none' (monitoring only) to see what email sources are authenticating. After reviewing reports for a few weeks, you can switch to quarantine or reject.
Can I generate a DMARC record for subdomains?
Yes, you can set a separate subdomain policy (sp) in the generator. If you don't specify one, the main domain policy applies to subdomains as well.
Is the DMARC generator free?
Yes, Emailer's DMARC generator is completely free to use. You can generate as many records as you need without any cost.
