Why your domain can be at risk even if you’ve never been hacked
Many companies discover the problem too late: customers receiving fake emails “from your brand,” suppliers double-checking requests via WhatsApp, or legitimate campaigns suddenly landing in spam.
The frustrating part is that this can happen even if none of your internal accounts have been compromised. In email security, if your domain is not properly authenticated, attackers can impersonate your domain and send messages that appear to come from your organization. The impact is twofold: brand reputation damage and poor deliverability.
The most common cause: incomplete or misconfigured authentication
Real email protection is based on three pillars: SPF (who is allowed to send), DKIM (message signing), and DMARC (policy and enforcement).
In practice, many organizations struggle with:
multiple tools sending email (marketing, invoicing, CRM, support),
SPF records at their lookup limit or incorrectly configured,
DKIM enabled only for some services,
DMARC stuck in monitoring mode indefinitely,
or SPF/DKIM alignment issues where the visible “From” domain does not match the authenticated domain.
This combination is exactly what attackers exploit—and what causes mailbox providers to distrust your messages.
What to check if your emails go to spam or your domain is being spoofed
These are common searches people make once issues start appearing:
“my emails suddenly go to spam”
“someone is spoofing my domain”
“how to stop phishing using my domain”
“how to configure DMARC without breaking email delivery”
In most cases, the root cause is the same: DMARC is not enforced with a strict policy, or authentication fails for legitimate senders.
The practical solution: moving from DMARC monitoring to enforcement
Applying DMARC enforcement (such as reaching p=reject) is what actually stops domain spoofing. But it’s also the step many companies fear: “what if legitimate emails stop being delivered?”
The right approach usually involves:
- identifying all legitimate email sources,
- aligning SPF and DKIM correctly,
- applying DMARC gradually,
- monitoring and fixing issues until enforcement is reached.
Skysnag focuses precisely on automating this process, offering real-time monitoring and a controlled path to enforcement without disrupting legitimate email flows.
How Skysnag helps when you need fast results and less manual work
Instead of relying on manual DMARC report analysis and complex DNS changes, Skysnag automates DMARC management and significantly shortens the time needed to reach enforcement.
Its platform also addresses common SPF issues, such as lookup limits and syntax errors, and simplifies DKIM alignment across multiple email services.
Bonus: deliverability and brand trust with BIMI
Beyond preventing spoofing, many organizations want to improve brand visibility and trust in the inbox. Skysnag supports the path to BIMI and Verified Mark Certificates (VMC), helping brands display their logo in supported email clients and reinforce brand recognition.
Quick checklist for businesses
Use this checklist to assess your current situation:
You know exactly which platforms send email on behalf of your domain.
Your SPF record is valid and not exceeding lookup limits.
DKIM is enabled wherever possible.
DMARC is configured and not left only in monitoring mode.
You have a plan to gradually move toward enforcement (p=reject).
Conclusion
If your goal is to prevent domain spoofing and improve email deliverability, the key is properly managing SPF, DKIM, and DMARC and moving toward enforcement without breaking legitimate email traffic. Skysnag is designed to automate and accelerate this journey.
And if you want expert guidance, Aufiero Informática can help you implement Skysnag according to your environment, email volume, and business needs—so you move from reacting to incidents to preventing them.
