In today’s interconnected email ecosystem, ensuring effective email deliverability and robust email security is paramount for organizations and domain owners. The Domain-based Message Authentication Reporting and Conformance (DMARC) framework provides a trusted solution to combat spoofing, phishing, and malicious actors by enabling organizations to implement advanced email authentication protocols.

Cyber incidents this week ranged from large-scale scraping to high-impact software and supply chain risks. An activist group claims to have scraped tens of millions of tracks from a major streaming platform, raising fresh copyright concerns. Separately, a critical n8n flaw could allow code execution on exposed instances. Other reports covered a notarized macOS stealer campaign, a GitLab breach impacting a car maker’s customers, and malicious Chrome extensions abusing proxy access to steal credentials.
Simple Mail Transfer Protocol (SMTP) servers form the backbone of global email communication. These servers facilitate the sending, relay, and final delivery of emails between email clients and servers across the internet. Whether you rely on a free SMTP server for personal use or integrate an advanced SMTP service in enterprise email marketing, the SMTP server determines how efficiently and securely your email messages reach recipients.
No matter how advanced technology has become, email is still the backbone of business communication. That’s precisely why it is one of the most targeted and abused attack surfaces online. For any business organization, it is important to understand that poor email deliverability, phishing, and domain impersonation — all these issues stem from one major problem: an unhealthy email ecosystem.
DomainKeys Identified Mail (DKIM) is an essential standard for safeguarding domain names, bolstering email authentication, and preserving your organization’s sender reputation. As threats like email spoofing, phishing, and other malicious activities grow increasingly sophisticated, maintaining a rigorous DKIM check process and routinely performing a DKIM record test have become integral best practices for any outbound email infrastructure.
For businesses that rely on prompt communication with clients, partners, and internal teams, dependable email delivery is essential. However, numerous organizations still use the default email servers provided by web hosting companies or ISPs, leading to challenges such as low deliverability rates, spam filtering issues, restricted sending limits, and limited insight into email performance. As inbox providers enhance their authentication and security protocols, these drawbacks can harm both brand reputation and customer confidence.
