Cyberattacks and data breaches continue to hit hard this week! A scam targeting U.S. residents through fake DMV messages is harvesting sensitive data. At the same time, separate breaches have exposed insurance documents at Scania, journalist accounts at The Washington Post, and over a million records from Cock.li’s email service is included. WestJet Airlines is also facing internal disruptions due to a cyberattack. Here’s a quick breakdown of the most important incidents and how to stay safe.
The common ‘DMARC policy not enabled’ error pops up during a reverse DNS lookup, indicating that no valid policy is defined in your domain’s DMARC record. Without a DMARC policy, a DMARC record is of no use— it provides no protection from phishing and spoofing emails sent from your domain.
Crafting a follow-up email that gets results is an art form.
It’s about striking the right balance between being helpful and direct. You want to remind your recipient of your value without being too pushy and encourage them to act. Let’s take a look at some key details you should include in your email follow-ups.
Tackling common SPF errors: A cheatsheet for safer email authentication
by DuoCircle
SPF, or Sender Policy Framework, is the foundational authentication protocol that tells receiving servers which sources are allowed to send emails on behalf of your domain. Now, if something goes wrong with your SPF setup, it may not only have a direct impact on your email deliverability and security, but also have a ripple effect across other authentication checks, such as DKIM and DMARC. Emails may land in spam, get rejected outright, or leave your domain vulnerable to spoofing attacks—all because of a misconfigured SPF protocol.
This week’s cybersecurity round-up covers serious threats hitting various sectors, including transportation, healthcare, and retail. Key cybersecurity incidents include a massive data breach in a governmental department, a ransomware attack crippling life-threatening healthcare operations, and a sneaky job scam targeting recruiters. Major giants from the business world have also confirmed cyberattacks that impacted employees and disrupted critical business workloads. Read on for full details, known risks, and what’s being done in response, strengthening the defence mechanisms.
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.
How SPF, DKIM, and DMARC quietly protect every email you send?
by DuoCircle
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.
