Prevention is always better than cure. Here are some tips to avoid being blacklisted:
Use Double Opt-In: Ensure that your subscribers explicitly confirm their subscription to your email list. Regularly Clean Your List: Remove inactive or invalid email addresses to reduce bounce rates and spam complaints. Monitor Engagement: Track your email metrics to identify any sudden drops in performance, which might indicate deliverability issues. Authenticate Your Emails: Use SPF, DKIM, and DMARC authentication to prove that your emails are legitimate.
