Email delivery issues, manifested as messages failing to reach intended recipients, frequently stem from actions taken by email providers or recipient servers. These actions, often automatic, are designed to protect users from spam, phishing attempts, and other malicious content. For example, a large volume of emails sent from a new IP address within a short timeframe could trigger a block, even if the content is legitimate.
Understanding the reasons behind email blocking is crucial for maintaining effective communication, especially in professional contexts. Undelivered emails can disrupt business operations, delay critical information, and damage sender reputation. Historically, the rise of unsolicited commercial email necessitated increasingly sophisticated filtering techniques, which, while effective, can sometimes result in legitimate emails being misidentified as spam.
