Increased Spam Reports: Sending emails to uninterested recipients can result in higher spam complaints. Lower Deliverability Rates: ISPs may block or filter your emails if they detect poor list hygiene, affecting your overall deliverability. Higher Costs: Paying for inactive or invalid email addresses can increase your marketing costs unnecessarily. Damage to Sender Reputation: Consistently poor email hygiene practices can harm your sender reputation, making it difficult to reach your audience.
