The phrase in question appears to be a corrupted or unconventional construction intended to reference the act of formally referencing an electronic message. Specifically, it likely describes the inclusion of email correspondence as evidence or support within a document, argument, or academic work. For example, a researcher might incorporate excerpts from email exchanges with a subject to illustrate a specific point in a study.
The practice of documenting email communications is crucial for maintaining transparency and providing verifiable sources. Proper citation of such correspondence lends credibility to the work and allows readers to examine the original context of the statements. Historically, the need to formally acknowledge electronic sources arose alongside the widespread adoption of email as a primary form of professional and personal communication. This practice helps to avoid plagiarism and strengthens the validity of research findings.
