Their system will not accept an email over 10mb and you will get the failure notice. I had to split my application package in to 2 separate emails less than 10mb each. I attached each required item as a separate PDF within the same email it does not need to be one PDF document. Just make sure to put the required information in the subject line of both emails. I put email 1of 2 and 2 of 2 also in the subject line.
