There are plenty of communication channels out there, but the one that has stayed and created the most significant impact on businesses is email. You might agree with us when we say that email is indispensable when it comes to connecting your brand to your clients.
Email sending services are platforms that facilitate the management and delivery of transactional and marketing emails for businesses, ensuring high deliverability rates. These services often include features such as robust APIs, dynamic email templates, and user management capabilities, all designed to enhance communication efficiency and engagement with customers.
The current version of DKIM (DomainKeys Identified Mail) that you might be using was introduced in 2011. A lot has happened in the cybersecurity world since then. Indeed, we have evolved a lot, but so have the hackers! They’ve become smarter, employing sophisticated tricks to impersonate emails, steal data, and scam companies.
With the rise of remote work, ensuring secure email communication has never been more critical. Cyber threats continue to evolve, making it essential for businesses and remote employees to adopt robust email security measures. Whether you are an organization managing a distributed workforce or an individual working remotely, understanding and implementing best practices for secure email communication can protect sensitive information and prevent cyberattacks.
BIMI enhances email security by allowing brands to display their logos alongside authenticated emails, which helps recipients easily identify legitimate communications and reduces the risk of phishing attacks. To implement BIMI effectively, brands must first establish DMARC (Domain-based Message Authentication, Reporting & Conformance) to prevent domain spoofing and ensure that their emails are properly authenticated.
Every business faces risk. A lawsuit, a contract dispute, or poor financial management can threaten its survival. Without proper protection, owners may lose assets or struggle to recover from legal and financial setbacks.

This week’s bulletin highlights some serious incidents that could impact individuals and businesses alike. From hackers spreading malware through NPM packages to cryptocurrency-stealing schemes, cybercriminals are finding new ways to trick people and exploit vulnerabilities. You can stay informed, stay cautious, and take action to protect yourself from these threats with our detailed coverage.
Encryption and hashing are the two fundamental techniques of the digital landscape. These are used to protect the integrity and authenticity of data so that threat actors don’t steal or intercept it. At first glance, these two terms may seem the same, which is why many people use them interchangeably. However, they serve distinct purposes and operate in entirely different ways. While encryption is used when you want to secure data by making it unreadable to unauthorized users, hashing does the job of verifying data integrity by generating a unique fingerprint.
An SMTP open relay is a mail server configuration that allows users to send emails through the server without authentication, making it vulnerable to exploitation by spammers for sending unsolicited emails. This practice not only leads to increased spam activity but can also compromise the server’s reputation and deliverability rates, necessitating robust security measures to prevent unauthorized access.
These days, there’s so much talk about the classic technique of deception— phishing. Almost every day, you hear stories, read headlines, and even experience how cyber crooks deceive unassuming users into giving sensitive information, downloading a malicious file, or clicking on a fake link. These attackers usually make their way into your systems through fake emails pretending to be from your bank, text messages warning about “suspicious activity,” or phone calls from scammers claiming to be customer service representatives.
A permerror in SPF indicates that there is a permanent error with the Sender Policy Framework (SPF) records, preventing proper interpretation of your domain’s email authorization. To resolve this issue, you should ensure that there are no multiple SPF records for your domain, check for syntax errors in the existing record, and limit the number of DNS lookups to comply with the SPF specification, which means using efficient mechanisms and avoiding unnecessary complexity.
DMARC TempErrors refer to temporary authentication issues related to email standards such as DKIM and SPF, which can lead to failures in DMARC validation. These errors can result in sporadic email delivery problems, particularly when using Microsoft servers, and addressing them may involve utilizing monitoring services like dmarcian.com for insights into performance metrics and error diagnostics.
If your organization sends out bulk emails, you absolutely cannot overlook its security aspect.

Your wait is over as we’re back with cybersecurity’s latest this week! We’ll discuss about a data breach impacting policyholders of a significant insurance organization, a notorious malware spam host resurfacing under a new provider, a new scam targeting US executives using deceptive postal mail; experts recently uncovered a new botnet that is infecting thousands and a concerning discovery of sensitive API keys within AI training datasets. Let’s not wait further and dive in!
A DKIM selector is a string included in the DKIM signature of an email, which helps the recipient’s mail server locate the corresponding public key stored in DNS records for verification purposes. It is essential for ensuring that emails sent from your domain can be properly authenticated, thereby enhancing your email security and integrity.
Migrating from one Office 365 tenant to another can feel a bit like planning a big move: there’s excitement for new beginnings, but also a mountain of details to manage! Whether you’re merging companies, reorganizing, or simply upgrading, a smooth transition is key to keeping everything running without a hitch. With the right strategies and tools in your corner, you can make the process simpler and less stressful.
Threat actors are becoming more sophisticated, and the safety of the digital space is taking a toll because of it. Over the past few months, cybersecurity experts have noticed a new phishing scam tactic in which bad actors send fake meeting invitations that redirect the invitees to phishing websites. These invites look exactly like the original Google invites, and even the phishing website is cloned so well that it’s difficult to catch its fakeness. Since the counterfeit platforms are flawless, the success rate of these attacks is extremely high; users are entering sensitive details and downloading malicious links without batting their eyes.
In today’s fast-paced tech world, many businesses are seeking ways to streamline their IT services and improve customer satisfaction, but how do they do that effectively? Enter the MSP Partner Program—a game-changing initiative specifically designed for Managed Service Providers (MSPs).
The ‘fo’ tag in DMARC stands for ‘failure options.’ It’s an optional tag that helps domain owners specify the types of authentication and alignment issues that must be reported. This tag supports four specific types of failure reports: fo=0, fo=1, fo=d, and fo=s. The ‘fo’ tag can combine multiple reporting options, enabling you to create a customized reporting strategy that aligns best with your preferences and risk tolerance.
In a digital world where email is still a primary mode of communication, protecting your domain from malicious attacks has never been more critical. You may think email security only pertains to big corporations, but every organization, large or small, should be on alert against threats like phishing and spoofing.
