Ignoring complaints can lead to severe consequences, including:
1. Spam Reports: When recipients mark your emails as spam, it signals ISPs that your content is unwanted, potentially leading to your emails being blocked. 2. Reputation Damage: Persistent complaints can tarnish your brand's reputation, making it harder to build trust with your audience. 3. Deliverability Issues: High complaint rates can reduce your sender score, leading to lower deliverability rates and fewer people seeing your emails. 4. Legal Implications: Non-compliance with anti-spam laws like CAN-SPAM or GDPR can result in hefty fines and legal action.
