In today’s digital world, terms like data leak and data breach are frequently used by news outlets, security blogs, and IT professionals—often interchangeably, but incorrectly. At DMARCReport, we believe that understanding the distinction between a data leak and a data breach is essential for building strong data-protection strategies. When combined with security measures like DMARC,…
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…
The best tools for bulk DMARC lookup across hundreds of domains are a mix of commercial SaaS platforms (e.g., DMARC Report, dmarcian, EasyDMARC, PowerDMARC, Valimail Monitor, MXToolbox, WhoisXML API) and high-performance open-source utilities (e.g., massdns, ZDNS, ProjectDiscovery dnsx) combined with scripting libraries (Python dnspython, Go miekg/dns) for automation and validation at scale. Bulk DMARC lookup…
Compared to MXToolbox, Valimail, and DMARCian, DMARC Analyzer provides stronger guided onboarding and automated validation than MXToolbox and DMARCian but less end-to-end automation than Valimail; in practice, organizations tend to reach p=reject fastest with Valimail or DMARC Report, steadily with DMARC Analyzer, slower with DMARCian, and slowest with MXToolbox. DMARC setup is notoriously cross-functional—touching DNS,…
In our recent webinar titled “From Setup to Success: Secure Your Emails with DMARCReport,” we explored essential aspects of email security, with a deep dive into authentication protocols and best practices. The session was rich in content and attracted many participants; yet, we couldn’t cover all questions during the live Q&A. In this post, DMARCReport…
The best DMARC checker depends on your goals: choose dmarcian for deep DMARC-specific analytics and guided rollout, MXToolbox for fast diagnostics and budget-friendly monitoring, Proofpoint for enterprise-scale enforcement with threat intelligence, and consider DMARC Report to bridge gaps with scalable parsing, automation, and cost efficiency across SMB to multi-domain enterprises. DMARC (Domain-based Message Authentication, Reporting…
For small businesses with minimal IT staff, the best DMARC record generators are GUI-based wizards—especially DMARC Report’s DMARC Wizard—alongside dmarcian, EasyDMARC, PowerDMARC, MXToolbox, and Google Admin Toolbox, because they combine pre-validated records, SPF/DKIM alignment guidance, and optional one‑click DNS publishing to minimize setup time and errors. Getting DMARC right delivers immediate value—stopping spoofing/phishing and improving…
Email authentication is not a one-time job; it requires ongoing maintenance and adherence to hygiene practices post-implementation. A well-maintained DMARC record increases the possibility of most of your genuine emails landing in the primary inbox of the intended recipients. Not just this, but it works efficiently to prevent phishing emails from sitting in the target’s…
In today’s threat-filled digital landscape, protecting your domain from email spoofing and phishing attacks is essential to maintaining trust and deliverability. An online DMARC policy checker plays a crucial role in this defense by verifying the alignment of SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records with your domain’s “From” address. This verification…
Email security is a critical concern for organizations facing growing threats like phishing, spoofing, and business email compromise. One of the most effective ways to protect your domain and ensure trusted communication is by implementing DMARC — a protocol that verifies email authenticity and prevents unauthorized use of your domain. By leveraging SPF and DKIM,…
In 2025, email deliverability has become even more complex. Big email providers like Gmail and Microsoft have changed the rules for who can reach the inbox. Although DMARC, SPF, and DKIM setups are essential to email deliverability, these three on their own may still not be enough. The foundation of success relies on two essentials:…
Emails from government or public sector agencies are not just a means of communication or dissemination of important information; they also reinforce trust and authority. Imagine if someone receives a fraudulent email from a seemingly official government address, the trust they place in that institution would be shattered. After all, it is more than just…
Configuring an SPF (Sender Policy Framework) record for Gmail is one of the most effective ways to protect your domain from email spoofing and phishing attacks. SPF works by verifying which mail servers are authorized to send emails on behalf of your domain, ensuring that malicious actors cannot impersonate your brand or send fraudulent messages…
Email deliverability plays a vital role in determining whether your messages successfully reach your audience or get trapped in spam filters. One of the most critical factors influencing this is your email IP reputation — a score that reflects how trustworthy your sending IP address appears to internet service providers (ISPs). When your IP reputation…
