DET is a proprietary email format used by Sage ACT!. It is used to store both email messages and attachments, though only a single message or attachment can be saved in a DET file.

DET files may be generated automatically when an .IML file is attached to a contact within ACT! or moved from the Inbox to another folder.

Important: ACT! 6.0.3 and later saves email messages in the .IMA format.
