Affiliate email marketing is one of the most stable income channels for affiliates – open rates reach 50% and even more in some industries – but there are still quite a few obstacles to overcome, from spam filters to phishing attacks to fake sign-ups. As an advertiser, you’d like to nullify or at least mitigate all those risks, so you can get purchase-prone leads that match your demographics.
Every email sent from your domain needs to be from a clean, legitimate sender. Even a single communication attempt by a threat actor impersonating your brand can lead to phishing, spoofing, business email compromise (BEC), and ransomware attacks. This is exactly where SPF, DKIM, and DMARC step in every time an email is sent from your domain.
You might be under the impression that the three major email authentication protocols are mutually exclusive. Well, this might be the most common misunderstanding and is particularly true for SPF (Sender Policy Framework).
We are discontinuing Mail Hosting Services and ContinuityEmail effective September 30, 2025. After nearly 20 years of providing email hosting, we’re ending these services to focus on areas where we can better serve modern business needs: email authentication, DMARC implementation, and deliverability solutions. Customers have four months to transition to providers like Google Workspace, Microsoft 365, or other platforms that offer the integrated business tools today’s companies require.
When Mail Hosting Services was launched in June 2005, the digital landscape looked vastly different. Social media was in its infancy, smartphones were still called “PDAs,” and email was the undisputed king of digital communication. Twenty years later, as we announce the end-of-life for our email hosting services, we can’t help but reflect on the incredible journey email has taken—and the rumors of its demise that never quite materialized.
As a business owner, you probably send emails almost every day, whether they are marketing emails, order confirmations, important instructions, or even internal updates. These emails are essentially an extension of your brand’s identity, and we’re sure that the last thing you want is to taint it or for someone to mess with it.
WebRTC powers your everyday video calls, chats, and real-time data sharing. By eliminating the need for central servers, it reduces response times for communication. However, these direct connections can expose your actual IP address, even if you use a VPN or proxy. WebRTC leaks can reveal your identity and location, undermining your privacy and security online.

From hidden backdoors on GitHub to fake Fastlane plugins hijacking social media bots, this week’s cyber updates spotlight how trust in familiar tools is being silently exploited. Major brands like The North Face and Cartier are also dealing with breaches, and U.S. agencies face urgent patch deadlines due to active vulnerabilities. Let’s take a closer look!
Not every email that you send is important, but transactional emails— the ones that confirm your payments, send shipping updates, or reset your password—are especially critical. That’s not just because they carry important information, but also because your users need to act on it quickly.
When it comes to managing your email communication, ensuring that your messages land in the right inbox can feel a lot like navigating a minefield. One misstep, and your carefully crafted emails could end up getting sidestepped—or worse, flagged as spam! A core part of this journey involves understanding and configuring SPF records, which serve as gatekeepers for your domain’s email integrity.
We’ve all been there— forgotten passwords, set ones that were too simple to be hacked, or used the same passwords across all accounts. But ideally, your priority should be security, not convenience.

We’re back with the week’s cybersecurity round-up of a mix of high-stakes breaches, targeted malware campaigns, and growing concerns around supply chain vulnerabilities. Each of these incidents highlights different tactics attackers are using to exploit trust, access, and visibility. Read on for all the details.
Email is a cornerstone of communication, but imagine sending a message that never arrives or worse, ends up in someone’s spam folder. Frustrating, right? That’s where SPF records come into play. They help email servers decide whether the emails they receive are from someone who’s actually allowed to send them. You might think creating an SPF record sounds complicated, but it’s simpler than you might expect. It’s all about making sure the right people can send messages on your behalf while keeping the unwanted ones at bay. This guide will walk you through setting up your own SPF record step by step, ensuring your emails get where they need to go—without any hiccups along the way!
Attackers often outsmart the cybersecurity custodians, and a DKIM replay attack is one such technique exploited by them to sign, seal, and send fraudulent emails using a valid DKIM signature.
Understanding SPF Records for Email Security Have you ever wondered why some of your emails vanish into spam folders while others land right in the inbox? The secret often lies in something called the SPF record. Think of it as a digital passport for your emails, showing the world which servers are allowed to send messages for your domain. Properly managing this little-known aspect can save you from headaches and ensure that your emails are delivered with confidence.

This week in cybersecurity–a student admits to a massive school data hack, a major mobile network outage turns out to be a cyberattack, and hackers are actively spying on global aid operations. We also look into a DNS hijacking campaign affecting top organizations, and a trusted VMware tool gets caught in a malware-laced supply chain attack. Here’s a quick look at what’s been happening.
Email is a vital part of our everyday communication, especially for businesses. But did you know that without proper safeguards, your emails could be at risk of being spoofed by cybercriminals? That’s where SPF records come in. Setting up an SPF (Sender Policy Framework) record gives your domain the protection it needs against email impersonation, ensuring that only trusted servers can send emails on your behalf.
It’s well known that you need to have a strong defence mechanism in place to ward off phishing attacks. Speaking of which, Domain-based Message Authentication, Reporting, and Conformance (DMARC) stands out as an email security protocol. Not only does it protect your domain from being misused by attackers, but it also gives you control over how unauthenticated emails are handled.
In the digital age, ensuring that your emails reach their intended recipients without getting lost in the spam folder is crucial. Just think about how frustrating it can be when you send an important message, only to find out later that it was never received. An effective way to enhance your email deliverability and security is by using a Sender Policy Framework (SPF) record. But what exactly does that mean? Simply put, an SPF record tells email servers which senders are allowed to send emails on behalf of your domain. Crafting these records might seem daunting, but with the right tools, you can quickly create a solid SPF configuration. In this article, we’ll explore some of the best SPF record generators available and how they can simplify this vital task for you.

The cyber threat landscape has always been complex and evolving, but the advent of AI has empowered threat actors to bypass security filters more easily than ever. They are now penetrating deep into every sector, affecting interconnected operations at multiple levels. AI-backed deception has led to a stage where now a staggering 87% of global organizations have faced an AI-powered cyberattack in the past year.
