Failing to keep your data clean can result in several negative outcomes:
Higher bounce rates, which can damage your sender reputation and result in your emails being marked as spam. Reduced engagement rates, as irrelevant or outdated emails fail to resonate with recipients. Increased costs, since many email marketing platforms charge based on the number of subscribers. Legal risks, particularly with regulations like GDPR and CAN-SPAM, which require accurate and up-to-date subscriber information.
