How Do Spam Filters Work and How Can You Avoid Them?
Spam filters use various criteria to determine whether an email should be marked as spam. Factors include the content of the email, the sender's reputation, and the presence of spammy keywords. To avoid spam filters, use reputable ESPs, ensure your email content is relevant and valuable, and avoid using too many promotional words. Tools like SpamAssassin can help you test your emails for spam triggers.
