Using unreliable data in email marketing can lead to several negative outcomes:
Low Engagement: Irrelevant or incorrect content can result in low open and click-through rates, harming your campaign's effectiveness. Increased Unsubscribes: Subscribers may unsubscribe if they receive content that does not match their interests or preferences. Reputation Damage: Sending emails to invalid or incorrect addresses can damage your sender reputation and lead to higher bounce rates. Non-Compliance: Using data from unreliable sources can lead to non-compliance with data protection regulations, resulting in legal penalties.
