What is Spam Filtering?
Spam filtering is a crucial process in email marketing that involves identifying and blocking unsolicited, unwanted, and potentially harmful emails. This helps maintain the integrity of your email campaigns and ensures that your messages reach your intended audience without being flagged as spam.
How Does Spam Filtering Work?
Spam filters use various algorithms and techniques to evaluate the content of an email. They analyze factors such as
email headers, keywords, links, and the sender's IP address to determine whether an email is spam. If an email meets certain criteria, it is flagged and moved to the spam folder.
