What is IP Blacklisting and How Can It Be Avoided?
IP blacklisting occurs when your sending IP address is added to a list of known spammers, causing your emails to be marked as spam. To avoid IP blacklisting, follow these best practices:
Use a reputable email service provider (ESP) that monitors and maintains their IP addresses. Ensure that your email list is clean and up-to-date by regularly removing invalid addresses. Implement double opt-in to verify that recipients genuinely want to receive your emails. Monitor your email metrics, such as open rates and bounce rates, to identify potential issues early.
