Summary
To get off email blacklists, experts and email marketers suggest a comprehensive strategy. This includes identifying which blacklists you are on using online tools and directly contacting the blacklist administrator or following their delisting process. Each blocklist has its own delisting procedures, so following their instructions is crucial. Addressing the underlying reasons for blacklisting, such as spam complaints or policy violations, is essential before requesting removal. Proactive measures include maintaining good email hygiene (cleaning lists, double opt-in, clear unsubscribe options), monitoring your sending reputation, gradually warming up new IPs, using dedicated IPs, employing email validation tools, and authenticating your email with SPF, DKIM, and DMARC. Developing relationships with postmasters at ISPs can also expedite the delisting process. Maintaining a positive sender reputation and adhering to sender guidelines are vital for preventing blacklisting.
