Email marketing continues to be one of the most effective digital communication channels for businesses worldwide. Platforms such as Mailchimp simplify campaign creation and audience engagement, but successful email delivery depends heavily on proper authentication. Without it, even legitimate emails risk being flagged as spam or rejected entirely. At DMARCReport, we work closely with organizations…
If you run an e-commerce business, email is not just a marketing channel. It is your order confirmation system, your password reset mechanism, your customer support line, and often your main revenue driver. Platforms such as WooCommerce, Shopify, Magento, BigCommerce, and PrestaShop rely heavily on transactional and marketing emails to operate smoothly. Now imagine those…
DMARC aggregate reports most commonly reveal SPF and DKIM authentication and alignment failures, unauthorized/forged senders, misconfigured internal or third‑party systems, and configuration pitfalls (SPF include limits, missing/rotated DKIM selectors, forwarding/mailing list artifacts, subdomain policy mismatches), and you should prioritize remediation in this order: 1) high‑volume spoofing that fails both SPF and DKIM, 2) legitimate business‑critical…
In today’s digital world, protecting your domain from spoofing, phishing, and misuse isn’t just a best practice — it’s essential. As email continues to be one of the primary channels for business communication, ensuring that your domain adheres to robust email authentication standards is crucial to maintaining deliverability, protecting brand reputation, and safeguarding your customers….
Common signs your domain has no DMARC record published include DNS queries for _dmarc.yourdomain returning NXDOMAIN or “no TXT answer,” missing or “DMARC not evaluated” entries in Authentication-Results headers, zero DMARC aggregate/forensic reports in your monitoring, no DMARC-related enforcement bounces or provider warnings, and consistent checks across all authoritative name servers and subdomains showing no…
Publish your DMARC record as a DNS TXT record at the host _dmarc.yourdomain (for example, _dmarc.example.com) in your authoritative DNS, and optionally at _dmarc.sub.yourdomain for subdomains you want to override—never at the bare apex without the _dmarc label and never as SPF/DKIM records. DMARC (Domain-based Message Authentication, Reporting, and Conformance) relies on a deterministic DNS…
In today’s connected world, cyber threats rarely knock before entering. Suspicious links — whether delivered through email, messaging apps, or social media — are among the most common dangers individuals and organizations face online. Clicking a malicious link can compromise sensitive data, install malware, undermine security systems, or open the door to phishing campaigns. At…
You do not need to be famous, controversial, or wealthy to become a target of doxxing. In many cases, victims are regular people who simply posted something online, joined a debate, or annoyed the wrong person. A single comment, tweet, or review can be enough to trigger someone into digging through your digital life. What…
The most common mistakes when setting up DKIM TXT records are syntax errors (quoting/semicolons/base64), selector/domain mismatches, incorrect key splitting or record type, weak or outdated keys and unsafe rotation, DNS propagation/TTL missteps, canonicalization/algorithm mismatches, and ignoring DMARC/SPF alignment requirements. DKIM (DomainKeys Identified Mail) uses a public key published in DNS to verify that a message’s…
To set up DMARCReport Free (DMARC Analyzer) and start receiving reports, publish a DMARC TXT record at _dmarc.yourdomain (for example.com → host: _dmarc.example.com, type: TXT, value: v=DMARC1; p=none; rua=mailto:[your-unique-address]@agg.dmarcreport.example; ruf=mailto:[optional]@forensics.dmarcreport.example; fo=1; adkim=r; aspf=r; sp=none; ri=86400; pct=100), verify your domain in the DMARCReport dashboard, confirm SPF and DKIM are correctly aligned for your mail flows, and…
Start protecting your G Suite (Google Workspace) email from phishing by enabling DMARC in monitor mode (p=none), properly configuring SPF and DKIM, publishing a DMARC TXT record with aggregate/forensic reporting, and using DMARCReport to analyze alignment data and gradually move to quarantine/reject. DMARC (Domain-based Message Authentication, Reporting, and Conformance) lets you tell receiving mail servers…
Here’s the fifth edition of the month. It revolves around the top cyber incidents that took place last week. Be it the Poland power grid cyberattack, or the “rn” typo trick used by hackers, the incidents hint towards one thing– increasing sophistication of the campaigns. The edition also talks about the Pwn2Own contest that revealed…
In today’s digital world, websites and email domains rely on the Domain Name System (DNS) to connect infrastructure, prove ownership, and secure communications. One of the most versatile tools in the DNS toolbox is the TXT record — a simple yet powerful type of DNS entry that carries text information used for domain verification, email…
Run continuous, automated DKIM monitoring with real‑time alerts at all times, run scheduled DKIM spot tests daily for high‑volume/frequently changing senders and weekly for stable low‑volume programs, and always test immediately before and after DNS/MTA changes and key rotations (hourly during active incidents). DKIM (DomainKeys Identified Mail) is a cryptographic signature that tells receiving servers…
Email authentication is more than just a best practice — it’s essential. As email threats continue to rise, weak authentication leaves your domain vulnerable to spoofing, phishing, and reputation damage. At DMARCReport, we believe every mail server owner should feel empowered to secure their infrastructure. One of the most impactful steps you can take is…
If your email domain has no DMARC record, attackers can freely spoof your domain to deliver convincing phishing and business email compromise (BEC), receiving servers won’t enforce a clear disposition for unauthenticated mail, you’ll have no visibility into abuse via DMARC reports, and your deliverability and brand reputation will degrade—especially with mailbox providers that now…
