Email continues to be one of the most widely used communication channels for businesses, consumers, and service providers worldwide. However, its widespread use has also made it a prime target for abuse. Phishing, spoofing, and impersonation attacks have increased dramatically, causing significant financial losses and eroding trust in email communication. To counter these threats, major…
To perform a DKIM lookup for your domain and verify email authentication, extract the DKIM selector from a signed message’s header, build the DNS name as selector._domainkey.yourdomain, query its TXT record with dig/nslookup (or an API), interpret the key tags, and optionally validate a message’s DKIM-Signature against that published public key. Context and background DKIM…
In an age where digital communication has become the backbone of business and personal interactions, email remains one of the most productive yet most exploited vectors for cybercriminals. Threat actors around the globe continually refine their tactics — from simple scams to sophisticated social engineering and phishing campaigns designed to dupe recipients into exposing sensitive…
If you run a website based on WordPress and rely on it to send emails — user sign-up confirmations, notifications, password resets, newsletters, or contact-form replies — then you probably know how finicky email deliverability can be. Out-of-the-box WordPress typically uses the PHP mail() function, which often results in un-authenticated emails that get flagged as…
1) Unclear pricing creates unnecessary stressWhen buyers can’t even estimate affordability, anxiety replaces curiosity. A pricing estimator lowers emotional friction and keeps prospects engaged instead of guarded. 2) It quietly disqualifies the wrong leadsPeople far outside your price range self-select out early, which saves your sales team time, energy, and morale. 3) Serious buyers engage…
Email continues to be one of the easiest ways for attackers to reach businesses. Phishing, spoofing, and brand impersonation attacks rely heavily on email because it is trusted, widely used, and difficult to police without proper controls. For service providers responsible for protecting client environments, securing email identity has become a foundational requirement. This is…
Implementing DMARC in Office 365 measurably improves inbox placement and reduces spoofing by giving Exchange Online Protection (EOP) and Outlook strong, aligned authentication signals (SPF/DKIM), but misconfiguration or unenrolled third‑party senders can lead to legitimate messages being quarantined or rejected—so phased rollout and continuous monitoring are essential. DMARC (Domain-based Message Authentication, Reporting, and Conformance) sits…
In today’s digital world, email continues to be one of the most essential forms of communication for businesses. From customer support to marketing campaigns and internal workflow, email delivers critical messages every second. But as the volume of email grows, so do threats like phishing, spoofing, and spam. That’s where proper email authentication steps in…
Use a DMARC creator like DMARCReport by entering the required tags (v=DMARC1 and p), selecting optional tags (rua, ruf, adkim, aspf, sp, pct, fo), validating syntax/alignment and report routing, then publishing the generated TXT record at _dmarc.yourdomain with a staged monitoring-to-enforcement plan and ongoing report-driven tuning. Context and background: what a DMARC creator does and…
In today’s email ecosystem, ensuring your messages are authenticated and trusted by mail servers is no longer optional: it’s mission-critical. Misconfigured email authentication is one of the leading causes of low deliverability, placement in spam folders, and spoofing attacks. That’s where SPF and DKIM come in: two foundational email authentication protocols that help protect your…
In today’s email threat landscape, phishing attacks have grown far more sophisticated than ever before. Gone are the days when scammers relied on bad grammar, obvious spoofed domains, or clearly malicious links. Modern attacks can mimic legitimate system alerts so convincingly that even tech-savvy users hesitate to dismiss them. One such evolving threat is what’s…
You implement a DMARC policy for a domain using Gmail/Google Workspace by configuring SPF and DKIM alignment for all senders, publishing a DMARC TXT record at _dmarc.yourdomain with monitoring (p=none, rua/ruf), analyzing reports, and then progressively enforcing p=quarantine and p=reject—using pct and sp for subdomains—while monitoring results in Google Admin/Postmaster Tools and DMARCReport. Implementing DMARC…
DMARC in monitoring mode provides visibility, but it is not sufficient. After all, visibility alone does not stop abuse. Once you know that there are unauthorized senders sending emails on behalf of your domain, continuing to monitor them without taking any preventive steps serves little purpose. At this stage, it is important that you start…
A DMARC Analyzer like DMARCReport reduces phishing from your domain by enforcing SPF/DKIM alignment through DMARC policy, mapping and eliminating unauthorized senders with aggregate/forensic reporting, and guiding you—via dashboards, alerts, and automated policy recommendations—from monitor to quarantine/reject without disrupting legitimate mail. DMARC (Domain-based Message Authentication, Reporting & Conformance) is the control plane for email identity:…
If you send email marketing campaigns using FreshMail, you already know how powerful and flexible the platform is. However, to ensure your emails actually reach the inbox and don’t get blocked, flagged as spam, or rejected outright, you need to authenticate your domain properly. That’s where SPF and DKIM come in — two critical email…
A DMARC record is a DNS TXT policy that tells receiving mail servers how to handle emails that claim to be from your domain by verifying SPF/DKIM alignment, and it matters because it prevents spoofing, improves deliverability, and gives you visibility through reports to enforce authentication safely. DMARC (Domain-based Message Authentication, Reporting & Conformance) builds…
