A distribution host may receive an electronic document from a sender device that includes content distribution designations. Based on the content distribution designations, the distribution host may determine that a portion of the electronic document is designated for distribution to multiple recipients. The distribution host may further determine that an additional portion of the electronic document is designated for distribution to a particular recipient of the multiple recipients. Accordingly, the distribution host may distribute the portion as a version of the electronic document to the recipient devices of one or more recipients that does not include the particular recipient. Further, the distribution host may distribute the portion and the additional portion as an additional version of the electronic document exclusively to a recipient device of the particular recipient.
