Companies provide points of contact for these types of legal process to be served on them - it is akin to the registered agent process. The FBI and other govt agencies do not have the authority to dictate how a company accepts this legal process, only that they comply with the legal order itself. As a result, govt agencies follow the methods of contact that a company provides, whether its a fax number, email address, mailing address, etc. Agencies are willing to follow the process that a company lays out because it makes engaging with that company easier. It is not in an agency's interest to make the process difficult (i.e. FBI demanding to use fax machines when a company already has a lawenforcment@company.com email set up).
