Re-engaging dormant subscribers is a delicate process that requires careful execution to avoid damaging your domain’s reputation, email deliverability, and overall sender trust. While reactivating inactive users can boost engagement rates and maximize the value of an existing email list, sending bulk messages to unresponsive subscribers without a strategic approach can lead to high bounce…

Reverse DNS (rDNS) lookups play a critical role in email security by verifying that the sending IP address of an email matches an expected hostname. This process helps prevent email spoofing, a common tactic used by cybercriminals to impersonate trusted senders and deceive recipients into opening malicious emails. Spoofing attacks exploit the trust associated with…

Publicly accessible blocklists play a critical role in cybersecurity by identifying and flagging domains that engage in malicious activities. These blocklists, maintained by security organizations, internet service providers, email security firms, and government agencies, serve as a first line of defense against phishing, malware distribution, spam, and other cyber threats. Their primary function is to…

Brand Indicators for Message Identification (BIMI) is an emerging standard designed to enhance email authentication while providing visual reinforcement of a brand’s legitimacy. It allows companies to display their registered logos directly in email inboxes, making it easier for recipients to identify legitimate senders at a glance. BIMI builds upon existing authentication protocols such as…

Blacklists play a critical role in maintaining internet security by preventing malicious domains from engaging in harmful activities such as phishing, spam distribution, and malware propagation. For domain owners, being placed on a blacklist can have severe consequences, including reduced email deliverability, loss of search engine visibility, and diminished trust from users and business partners.…

Transport Layer Security (TLS) is an essential protocol for encrypting communications between servers and clients, ensuring that data remains private and protected from interception. However, misconfigurations, protocol downgrades, and security vulnerabilities can weaken TLS encryption, exposing sensitive information and damaging a domain’s reputation. TLS Reporting (TLS-RPT) is a critical mechanism that provides visibility into encryption…

A domain’s reputation is one of its most valuable assets, influencing search rankings, email deliverability, and overall trustworthiness on the internet.

These unethical practices, often aimed at manipulating search algorithms…

Domain spam scores are a crucial metric in determining how trustworthy a domain appears to search engines, email providers, and cybersecurity monitoring systems. A high spam score can negatively impact email deliverability, search engine rankings, and overall online reputation. Businesses and website owners must actively monitor their domain’s spam score to prevent blacklisting, ensure reliable…

Forward Confirmed Reverse DNS (FCrDNS) is a critical configuration for domains that send email, improving security, email deliverability, and sender reputation. It is an advanced form of reverse DNS (rDNS) that ensures the IP address assigned to a domain resolves both forward and backward, confirming that the domain associated with an IP address matches the…

Website accessibility is an essential component of a trustworthy and credible online presence. Ensuring that all users, including those with disabilities, can fully navigate and interact with a website not only enhances user experience but also signals professionalism, inclusivity, and reliability.
