To avoid being flagged by DPI, email marketers should focus on creating high-quality content. Here are some tips:
Avoid spam triggers such as excessive use of exclamation marks, all caps, and certain keywords. Ensure that your email content is relevant and valuable to your audience. Maintain a healthy email list by regularly cleaning it to remove inactive or invalid addresses. Use email authentication methods like SPF, DKIM, and DMARC to prove the legitimacy of your emails.
