Occasionally an iPad user will want to browse their email without actually opening all of them, perhaps if they are in a hurry and don’t have time to properly read each one.
In this situation, reading the previews for each email can be handy. You can actually change the size of these previews to make sure you’re reading enough to get the idea of each message.
To do so, open the Settings app, and then head to the “Mail, Contacts and Calendars” option. There, you’ll need to press on the “preview” option.
There, you’ll be able to choose the size of your preview, anywhere from between one line to five lines.
