Since School Data Solutions utilizes Amazon Simple Email Service, we must maintain a good reputation. Our reputation is determined by how many bad emails we send compared to how many good emails we send. Because of this, we maintain a strict list of all email addresses that have bounced or complained and flag them as blacklisted. Once an email address is blacklisted, we will not attempt to send an email to it.
A hard bounce is typically caused by an email address not existing, the domain does not exist, or the target email server has blocked delivery. Email addresses that hard bounce are immediately flagged as blacklisted.
A complaint is when a user has reported that they do not want our email either by clicking the junk or spam button in their email client, complained to their email provider, or notified Amazon SES directly.
There is currently no automated mechanism to remove an email address from a blacklist. Should you believe you are blacklisted, please contact email@example.com for assistance.
