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.
![GitHub Backdoor Threat, Cartier Data Breach, Fake RubyGems Steal – Cybersecurity News [June 02, 2025]](https://www.duocircle.com/wp-content/uploads/2025/06/email-smtp-service-0905.jpg)
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.
