Systems, methods and computer program products for facilitating the simultaneous (e.g., side-by-side or via a “sliding” animation) displaying and viewing of email messages and any attachments to such email messages are disclosed. Such systems, methods and computer program products allow a user of a computing system to simultaneously view the textual portion of an email along with the contents of any attachments within one application, and without the need to switch between at least two software applications—the email reader application and the native (productivity) application used to create such attachment (e.g., a word processing software application, a spreadsheet application, a presentation application, a database application, a portable document format reader, a Web browser and/or the like).
