In the world of email communication, getting your messages to land in inboxes instead of spam folders is crucial. This is where Sender Policy Framework (SPF) records come into play. They act as a security measure, helping email providers determine if the emails sent from your domain are legitimate or potentially harmful. If you’re wondering…
The SPF protocol works efficiently only when your domain’s SPF record doesn’t have even a minor error. SPF is a highly sensitive email authentication mechanism; even a slight error can cause false positives or completely disrupt the authentication process. One way to evaluate the correctness of your SPF record is by regularly running it through…
There’s a common misconception among domain owners when it comes to email authentication protocols— we have configured SPF, DKIM, and DMARC, so we’re completely safe. They often mistake implementation for enforcement; they need to understand that there is a journey from SPF implementation to SPF enforcement. If you keep taking the two as the same,…
Threat actors seek ways to impersonate credible companies and their representatives to send phishing emails on their behalf. This way, the targeted recipients are more likely to open and interact with potentially fraudulent emails. However, if companies implement the SPF protocol for their domains and adhere to best practices, they can assist receiving servers in…
Microsoft has always prioritized email security, and in pursuit of this goal, it mandated that all bulk senders properly authenticate their messages. This means that anyone sending over 5,000 emails daily to Outlook, Hotmail, and other Microsoft consumer mailboxes must have properly configured SPF, DKIM, and DMARC records in place. If a bulk sender fails…
With around 3.4 billion spam emails sent daily, securing inboxes has become more challenging than ever. They not only clutter your inboxes and keep the servers busy, but also pose as major security threats to any organization. These seemingly harmless spam emails can lead to malware scams, phishing attacks, or even CEO fraud. It is…
Sender Policy Framework (SPF) is the foundation of your email security setup, and if SPF is not configured properly, all your efforts to protect your outgoing emails will fall apart. An SPF record is one of the most crucial aspects of SPF configuration; it basically includes a list of all the servers and services that…
Your carefully crafted marketing campaign just launched, complete with compelling subject lines and perfectly timed send schedules. Yet three days later, your open rates are disappointingly low, and customer responses are practically nonexistent. The culprit? Your emails are likely sitting in spam folders instead of reaching their intended inboxes. Email deliverability remains one of the…
Email security is on everyone’s radar—companies are closing every gap for threat actors to come in and exploit their email sending sources. Using SPF’s ‘-all’ mechanism is one of the strongest defense measures that domain owners and CISOs advocate to block email phishing attempts made on their behalf. While this hard defense layer ensures that…
Sender Policy Framework (SPF) is an email authentication protocol designed to prevent email spoofing — a common tactic in spam and phishing attacks. In today’s threat landscape, SPF plays a crucial role in cybersecurity by allowing receiving mail servers to verify whether an email claiming to come from your domain is actually authorized. By implementing…
