Adding RUA in DMARC means including an email address in your record to receive automatic reports on the use of your domain in emails. This helps you quickly detect fraud and improve the delivery of your messages, preventing imposters from using your name.
Imagine that someone sends fake emails using your web domain, as if they were from your company. This damages your reputation and can block your legitimate emails. The good news is that DMARC, with its key component RUA, gives you complete control.
In this article, I will guide you step by step through the simple process of setting it up.
What are DMARC and RUA records?
DMARC is like a shield for your email. It combines two pre-checks: SPF (who can send from your domain) and DKIM (digital signature of your messages). This way, receiving servers know if an email is real or fake.
The RUA record is the tag that activates aggregate reports. These are daily summaries of how your domain is used in sent emails. You don’t see individual details, but you do see patterns: how many failed, where they came from. It’s like a security log for your web domain.
Without RUA, DMARC works, but you lose valuable data. With it, you see the “RUA report” and act in time.
Why is it a good idea to add RUA to DMARC?
Protecting your email is not just about avoiding spam: it’s about maintaining your customers’ trust. A RUA report shows you if there are attempts at impersonation, such as phishing with your domain.
It also improves deliverability. Providers such as Google and Microsoft prioritize emails with complete DMARC. If you send newsletters or invoices, this reduces rejections.
And for you, it’s empowering: you detect problems early and realize if something is configured incorrectly. In short, RUA turns DMARC into an active, not passive, tool.
Steps to add RUA to DMARC
Before you begin, make sure you have SPF and DKIM ready. Without them, DMARC can block your own emails. Use free tools such as MX Toolbox to check.
What is SPF and DKIM authentication?
SPF tells who can send emails from your domain; DKIM digitally signs your messages to prove they have not been altered. Together, they prevent identity theft and improve the delivery of your emails.
Have you ever received an email “from a financial institution” that was fake? That happens because anyone can pretend to be you on the Internet. SPF and DKIM are like an ID and a notarized signature for your web domain. Without them, your emails will go to spam or worse: they will be used for fraud.
Check your previous settings
- Check SPF: It should list all the servers that send on your behalf.
- Configure DKIM: Sign your messages with a public key in DNS.
- Run a test: Send an email to a friend and check if it passes the tests.
If something fails, fix it first. This avoids surprises.
Create the DMARC record with RUA
The record is a simple text that you put in DNS. Use this basic structure:
v=DMARC1; p=none; rua=mailto:informes@tu-dominio.com
- v=DMARC1: Mandatory version.
- p=none: Initial soft policy (monitors without blocking).
- rua=mailto:your-email: This is where you put your address for the RUA report.
For a real example, Google Workspace recommends: v=DMARC1; p=reject; rua=mailto:postmaster@ejemplo.com. Change “none” to ‘quarantine’ or “reject” when you’re ready.
Add more emails if you want: rua=mailto:email1@dominio.com, mailto:email2@dominio.com. This way, several teams will receive copies.
Add the record to your DNS
Go to your domain provider dashboard (we recommend Neolo).
- Look for “TXT Records” or “Advanced DNS.”
- Create a new record:
- Name/Host: _dmarc.your-domain.com
- Type: TXT
- Value: Your complete record (e.g., v=DMARC1; p=none; rua=mailto:informes@tu-dominio.com)
- Save and wait 1-2 hours for it to propagate.
Check with dmarcian.com: enter your domain and see if the RUA report appears.
Tips for managing RUA reports
The reports arrive in XML, which can be confusing at first. But with these tricks, you can get the most out of them:
- Rotate emails in RUA: Change the address every month to avoid overloading a mailbox. Use automatic rules in your email to archive them.
- Integrate with simple alerts: Set up filters in Gmail to notify you if a RUA report shows more than 5% failures. This is faster than checking manually.
- Use subdomains for testing: Test RUA on a subdomain (e.g., test.your-domain.com) before your main domain. This prevents errors in production.
- Combine with free tools: Upload reports to postmastertools.google.com for automatic visualizations, not just raw XML.
Conclusion
Adding RUA to DMARC is a key step in protecting your web domain against fraud. With the record in place, you will receive RUA reports that guide you to flawless authentication.
Remember: start small, monitor, and adjust. Your email will be more secure and reliable in no time.
FAQs about adding RUA to DMARC
What happens if I don’t add RUA to my DMARC?
Without RUA, you don’t receive reports, so you don’t see problems until it’s too late. DMARC continues to protect, but without data to improve. It’s essential that you do it!
How long do RUA reports take to arrive?
They are usually daily, but the first one may take 48 hours. It depends on receivers such as Gmail.
Can I add RUA without changing my DMARC policy?
Yes, RUA is independent. Just add the tag without touching “p=”.
What do I do if my RUA reports show many failures?
Check legitimate senders in SPF/DKIM. Use tools like EasyDMARC to analyze.
