Yes—you can use DMARC to block phishing from true lookalike subdomains by enforcing a reject policy (via p=reject and/or sp=reject), but DMARC cannot block phishing from separately registered lookalike domains (typosquats), which require additional controls. DMARC (Domain-based Message Authentication, Reporting, and Conformance) authenticates the domain shown to recipients (the RFC5322.From) by aligning it with SPF…
As DNS users, domain administrators, and website operators know all too well: DNS configuration often feels like walking a tightrope. A small misconfiguration can mean your users can’t reach your site — or your email goes missing. Two DNS record types that are often sources of confusion are CNAME and ALIAS records. They can look…
To boost Gmail deliverability with DMARC, you must implement aligned SPF/DKIM/DMARC on your Google Workspace domain, stage policy from p=none to quarantine to reject while monitoring Gmail-specific signals, authorize third-party senders with aligned keys and SPF, handle forwarding with ARC, optimize SPF under lookup limits, enable BIMI, and continuously analyze RUA data with DMARCReport for…
By DMARCReport When you register a domain name — say mywebsite.com — you’re not done yet. To get the domain to actually load your website, or allow email to be delivered, you need to configure the Domain Name System (DNS) appropriately. Think of DNS as the internet’s “phone book.” Instead of human-readable domain names, computers…
When you implement DMARC, you do not just do it for the policy enforcement feature; it’s also the reporting aspect that makes the authentication protocol so effective. These reports give you a behind-the-scenes view of your email activity, from who is sending emails on your behalf, how those emails are being authenticated, to any suspicious…
Yes—DMARC aggregate (RUA) and forensic (RUF) reports can absolutely help you detect spoofing and phishing attempts by revealing who is sending as your domain, whether SPF/DKIM align, and where non-aligned traffic spikes point to active impersonation. DMARC sits on top of SPF and DKIM to answer a single question: did this message actually come from…

Implement DMARC for multiple domains and subdomains by standardizing a DNS template (SPF, DKIM, DMARC), inventorying all sending services, using parent-level inheritance with the DMARC sp tag where appropriate, centralizing rua/ruf reporting, rolling out p=none then gradually enforcing per domain (quarantine → reject) based on report-driven confidence, automating DNS and DKIM key management via APIs/IaC,…
Introduction At DMARCReport, we’ve always believed that email authentication and brand trust should go hand in hand. That’s why the recent update from Google — enabling support for Common Mark Certificate (CMC) under Brand Indicators for Message Identification (BIMI) — is big news for businesses of all sizes.

But building and maintaining your own email system takes time and technical know-how. And most founders simply don’t have that. Luckily, third-party email services can help.
