Monitoring blacklists is crucial for email deliverability. If your IP address or domain is listed, your emails may be blocked or sent to the spam folder, drastically reducing your campaign effectiveness. Regularly checking these lists helps you maintain a good sender reputation and ensures your emails reach their intended recipients.
