FAQs
Got any questions? Let’s answer them.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email security protocol that prevents cybercriminals from sending unauthorised emails from your domain.
Why do I need DMARC?
Without DMARC, anyone can spoof your email address. DMARC helps block phishing attacks, improves deliverability, and keeps your domain secure.
Will DMARC stop legitimate emails?
Not if it’s set up properly. We carefully monitor and tune your policy to ensure only unauthorised messages are affected, keeping your communications safe and uninterrupted.
