What Are The Best Tools For Validating And Analyzing A DMARC Record Example?

ByBrad Slavin

The best tools for validating and analyzing a DMARC record example are a combination of web validators (DMARCReport Validator, MXToolbox, dmarcian, DMARC Analyzer), command-line utilities (dig/host/nslookup, OpenDMARC), open-source parsers (parsedmarc), and APIs (DMARCReport API, SecurityTrails, WhoisXML) supplemented by deliverability testbeds (Gmail/Outlook header analysis, Mail-Tester, GlockApps) to cover both syntax accuracy and real-world enforcement outcomes. Why…

DMARC Deployment & Monitoring: A Practical Guide by DMARCReport

ByBrad Slavin

In today’s digital ecosystem, email remains one of the most vital communication channels for organizations worldwide. Yet, without strong safeguards in place, email domains can be abused by attackers to send phishing, spoofing, and other fraudulent messages that harm your brand, customers, and internal users. To protect your domain and ensure only authorized email senders…

Why is DMARC important for protecting emails sent from G Suite?

Why is DMARC important for protecting emails sent from G Suite?

ByBrad Slavin

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…

Why does Gmail reject or mark my messages as spam when my DMARC policy is strict?

Why does Gmail reject or mark my messages as spam when my DMARC policy is strict?

ByBrad Slavin

Gmail rejects or marks your messages as spam when your DMARC policy is strict because the messages fail DMARC alignment (SPF or DKIM pass but don’t align with the visible From domain), alignment is broken by forwarding/lists/intermediaries, or misconfigurations exist, and Gmail combines these results with reputation and engagement signals to quarantine or reject according…

How to maintain a good email sender reputation in 2026

How to maintain a good email sender reputation in 2026

ByBrad Slavin

Email platforms today are much stricter about security and trust, and have become far less forgiving than ever. This means even a minor slip-up could cost your brand visibility, credibility, and trust among the email service providers and recipients. Now imagine this happening repeatedly. If your outgoing emails often fail authentication checks, trigger spam complaints,…

New ClickFix Scam, Dental Practice Banned, UK MPs Targeted

New ClickFix Scam, Dental Practice Banned, UK MPs Targeted

ByBrad Slavin

Cybercriminals are getting smarter, quieter, and far more convincing. From a new browser-based ClickFix variant that slips past traditional security tools, to healthcare organizations facing legal action after phishing breaches, and even UK MPs being targeted through trusted messaging apps, recent incidents show how fast attack methods are evolving. These threats no longer rely on…

How can I check whether my domain’s DMARC policy is correctly configured for Gmail?

How can I check whether my domain’s DMARC policy is correctly configured for Gmail?

ByBrad Slavin

To check whether your domain’s DMARC policy is correctly configured for Gmail, validate your DMARC DNS TXT record syntax and tags, confirm SPF and DKIM alignment with your header-from domain, send test messages to Gmail and inspect Authentication-Results and Google Postmaster Tools, verify delivery and parsing of DMARC aggregate (rua) reports (noting Gmail does not…

Business Email Compromise vs Phishing Attacks — A Deep Dive by DMARCReport

Business Email Compromise vs Phishing Attacks — A Deep Dive by DMARCReport

ByBrad Slavin

In today’s hyper-connected digital world, email remains the backbone of business communication — and unfortunately, also one of the most exploited attack vectors used by cybercriminals. Sophisticated threat actors continually refine their techniques to deceive trusted recipients, impersonate legitimate senders, and manipulate end users into disclosing sensitive information or transferring funds. At DMARCReport, we believe…

Does a DMARC check verify SPF and DKIM alignment for my domain?

Does a DMARC check verify SPF and DKIM alignment for my domain?

ByBrad Slavin

Yes—DMARC explicitly evaluates SPF and DKIM authentication results and verifies their alignment with the message’s Header From domain, passing if at least one of SPF or DKIM both authenticates and aligns per your DMARC policy. DMARC (Domain-based Message Authentication, Reporting, and Conformance) exists to connect message authentication to domain identity as shown to recipients: the…

How can DMARC improve email deliverability and reduce phishing risks?

How can DMARC improve email deliverability and reduce phishing risks?

ByBrad Slavin

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…

How can I create a DMARC record for my domain to stop email spoofing?

How can I create a DMARC record for my domain to stop email spoofing?

ByBrad Slavin

To stop email spoofing, create and publish a TXT record at _dmarc.yourdomain.com with a value like v=DMARC1; p=reject; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-forensics@yourdomain.com; adkim=s; aspf=s; pct=100; fo=1; ri=86400 only after verifying that all your senders pass SPF and/or DKIM in alignment with your From domain. DMARC (Domain-based Message Authentication, Reporting, and Conformance) lets domain owners tell receivers how…

CNAME vs ALIAS Records — A Guide by DMARCReport

ByBrad Slavin

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…

Boost Deliverability with Gmail DMARC: What Every Sender Must Know

Boost Deliverability with Gmail DMARC: What Every Sender Must Know

ByBrad Slavin

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…

CNAME vs A Record: What Every Domain Owner Should Know

CNAME vs A Record: What Every Domain Owner Should Know

ByBrad Slavin

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…
