Routing of an unknown mail item

One or more non-transitory computer-readable media storing computer-executable instructions which, when executed by a processor on a computer system, perform a method for routing a mail item part, the method comprising:

• decomposing, using a processor device, a segment of the mail item part into a text string vector;
• quantifying, using the processor device, a first closeness between the string text vector and a first library vector that corresponds to a first mail item part destination;
• quantifying, using the processor device, a second closeness between the text string vector and a second library vector that corresponds to a second mail item part destination;
• and
• routing, using the processor device, the mail item part to that of the first and second mail item part destinations that corresponds to the greatest of the first and second closeness, the muting comprising:
• updating a routing record for the mail item with that of the first and second mail item part definitions that corresponds to the greatest of the first and second closeness;
• and
• based on the routing record, instructing a conveyor apparatus to route the mail item from a holding bin to a mail delivery service;
• and
• transmitting, using an electronic mail server, an image of the mail item part to that of the first and second mail item part destinations that corresponds to the greatest of the first and second closeness.
