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,…

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. If you’re sending emails to clients, subscribers…
You can create a DMARC record without breaking existing email delivery by first inventorying every legitimate sender, deploying DKIM and SPF for all of them, publishing a DMARC policy in p=none with full reporting (rua/ruf), validating alignment and fixing misconfigurations over 30–60 days, and then gradually stepping up to quarantine and reject using pct while…
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…

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,…
Email spoofing and phishing are still among the biggest causes of data breaches in 2025. That’s why businesses of all sizes are adopting DMARC to protect their domains from being used in fraudulent emails. But implementing DMARC is only half the job; choosing the right DMARC monitoring and management tool is what ensures your protection…
In today’s digital business landscape, email remains a primary communication channel—but also a frequent target for cyber threats such as phishing and spoofing. To safeguard professional correspondence, the Sender Policy Framework (SPF) plays a pivotal role in verifying that messages are sent from authorized servers. When effectively configured, SPF strengthens domain credibility, prevents impersonation, and…
