Most email clients contain a "subject" that allows the user to read an email message without actually opening it.
Answer:
preview.
Explanation:
There are many email providers, such as Microsoft Outlook, that allow the user to preview the email message without having to open it.
This technique is used by customers who receive a large volume of email daily and need to facilitate the management of incoming email to optimize time and response according to the relevance of each email.
To set the preview method, you must go to "options" and "preferences" and select the email preview option before opening, which will provide a split screen with a list of incoming emails, with subject, date and sender, in addition to the body of the message.
