Several factors can cause damage in email marketing, including:
Spam complaints: High volumes of spam complaints can lead to your emails being blocked or sent to the spam folder. High bounce rates: Sending emails to invalid addresses can damage your sender reputation. Low engagement: Poorly targeted or irrelevant content can lead to low open and click-through rates. Non-compliance: Failing to adhere to regulations like GDPR or CAN-SPAM can result in legal repercussions. Blacklisting: ISPs may blacklist your domain or IP if they detect suspicious activity.
