DMARC is important for protecting emails sent from G Suite (Google Workspace) because it verifies your domain’s messages via SPF/DKIM alignment and tells receiving servers to quarantine or reject spoofed mail, which dramatically reduces phishing while improving deliverability and visibility through standardized reporting. G Suite’s native security (SPF and DKIM) prevents many spoofing attempts, but…
DMARC improves deliverability and reduces phishing by enforcing domain-aligned authentication (SPF/DKIM) that mailbox providers trust to place legitimate emails in the inbox while blocking or quarantining spoofed messages at scale. DMARC—Domain-based Message Authentication, Reporting, and Conformance—adds a policy and reporting layer on top of SPF and DKIM so receivers can verify that a message claiming…
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…
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. 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…
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…
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…
