DomainKeys is an older technology that was combined with Cisco’s Identified Internet Mail (IIM) to develop DKIM—an email authentication protocol that prevents phishing emails sent from your domain from reaching recipients’ primary inboxes. Moreover, DKIM also ensures that nobody tampers with the message in transit. People often use these terms interchangeably, but let’s figure out…
DMARC authentication has become the norm in the cyber world, thanks to the revised email-sending policies introduced by Google and Yahoo. But what really makes this email authentication protocol a cult favorite? Apart from adding a layer of defense against unauthorized emails on your sender program and malicious cyberattacks, DMARC (Domain-based Message Authentication, Reporting, and…
In 2023, as many as 45.6% of total emails were identified as spam. While CISOs and technology enthusiasts are trying their best to ward off these attacks, cybercriminals are not behind in exercising their brain muscles to come up with newer ways of exploitation. One such relatively recent technique is a DKIM replay attack, where…
Marketing has been the supporting pillar of businesses and trades since the pre-industrial revolution era, and the proliferation of mobile devices has strengthened it. Today, email is one of the best channels of online marketing, with an ROI of $42 for every $1 spent. However, we can’t overlook how technical deliverability issues limit email marketing’s…
This guide is intended for email service providers and businesses involved in sending emails using their own customer’s domains for marketing, PR, billing, talent management, etc. Sending DMARC-compliant emails is beneficial for both parties, significantly optimizing email identification. If you aim to get the best of the best email delivery and visibility, consider the following…
Organizations often treat cybersecurity as a siloed function rather than a measure that needs to be practiced across departments and tiers. The year 2023 reported a global data breach cost of $4.45 million, and the United States encountered the highest average data breach cost, amounting to $9.48 million. While we don’t deny that your CISOs…
Emails are forwarded more often than we realize, and while DKIM isn’t affected by email forwarding, SPF and DMARC may break. For SPF, you create a list of senders officially authorized to send emails on your behalf. When an email is forwarded, the initial recipient becomes the sender; so, if the initial recipient’s IP address…
It was not long ago that Google and Yahoo revamped their sender policies and made best practices a mandatory requirement. For instance, until October 2023, measures like implementing email authentication protocols—SPF, DKIM, and DMARC were “nice to have.” However, starting in February 2024, authenticating their domains with these protocols is no longer an option but…
Domain owners use DMARC reports to instruct receiving mailboxes to quarantine or reject emails from unauthorized IP addresses. This helps minimize the possibility of victims engaging with potentially fraudulent emails sent on the pretext of official conversation from your company. However, Microsoft works a bit differently! Microsoft doesn’t reject emails because it considers the instances…
