A trust management engine maintains transferable files in a file data store of a data server accessible to users in a trust list of trusted users authorized to access the transferable files. The trust management engine facilitates a transmission of an email message containing a link to the transferable files to each of the users in the trust list. The email message is stored in an email server that is separate from the data server. The trust management engine receives a request from one of the users in the trust list of trusted users to access the transferable files in response to a selection of the link in the email message. In response to the request, the trust management engine facilitates a transmission of the one or more transferable files from the file data store to the requesting user.
