5. The computing system of claim 4 , the non-transitory computing memory having stored therein computer instructions that, upon execution by one or more processors, at least cause the system to: generate a user interface comprising a listing of emails, the listing of emails comprising the first email conversation and the second email conversation; and receive a selection of an email in the first email conversation; wherein the instructions that, upon execution by one or more processors, at least cause the system to generate the user interface identifying that an email is associated with a first email conversation that was previously linked to a second email conversation by a second user comprise instructions that, upon execution by one or more processors, at least cause the system to display on the user interface a preview of the selected email and a user interface feature identifying that a related email conversation exists.
