Prevention is always better than cure. Here are some best practices to avoid getting blacklisted:
Use permission-based email marketing. Ensure all recipients have opted in to receive your emails. Regularly clean your email list to remove inactive or invalid addresses. Monitor your email metrics such as bounce rates and spam complaints. Implement SPF, DKIM, and DMARC to authenticate your emails. Avoid using spam trigger words and phrases in your subject lines and email content.
