Ignoring feedback loops can lead to several negative consequences:
Increased Spam Complaints: Not addressing user feedback may result in continued spam complaints. Lower Engagement Rates: Ignoring FBLs can lead to a decline in open and click-through rates. Reputation Damage: ISPs use feedback to assess sender reputation. Ignoring this feedback can harm your sender score. Blacklisting: Persistent neglect can result in being blacklisted by major ISPs, drastically affecting your email deliverability.
