Typically we see that school district email address have trouble receiving our automated emails. This is due to the usually very stringent email security placed on district email servers. The contacts at the school districts will need to notify their IT department to white-list the automated email address, firstname.lastname@example.org. This means that our automated email address will be added to a list of safe and acceptable addresses and will allow our automated emails to pass through security and arrive at the inbox of the appropriate contact.
If you know ahead of time that you will be sending out automated emails to certain school districts, it is best to notify them before the program starts. By doing this, you can reduce the number of delayed emails and questions that you will receive from applicants.
