Note: There are just too many email clients around and we won’t be able to cover them all. This article only focuses on Gmail, Outlook and Thunderbird. Yahoo doesn’t come with plain text mode.
Gmail
In Gmail, there isn’t an explicit button for you to view your message in plain text. However, you can click the down arrow button beside “Reply” and select “Message text garbled?”. This will open a new window and display the email content in plain text.
This is what you will see.
Outlook.com
In the new Outlook.com, there is also no way for you to view email in plain text. The only available way is via the “View Source” option. In your email, click the “Actions” link and select “View message source”.
Scrolling through the source code, you should be able to see the email content in plain text.
Outlook 2003
To turn on the plain text option in Outlook 2003, go to “Tools -> Options -> Preferences”. In the E-mail area, click E-mail Option. In the Message handling area, select the “Read all standard mail in plain text” check box.
Outlook 2007
For Outlook 2007, the steps are slightly different. Go to “Tools -> Trust Center -> E-mail Security”. Under Read as Plain Text, select the “Read all standard mail in plain text” check box. To include messages that are signed with a digital signature, click to select the Read all digitally signed mail in plain text check box.
Outlook 2010
In your Outlook, you have to first click the File tab, and go to Options in the sidebar. In the window that pop up, click “Trust Center” on the sidebar, followed by the “Trust Center Settings” button.
Click “E-mail Security” and select “Read all standard mail in plain text” check box.
Thunderbird
In Thunderbird, all you have to do is to go to “View -> Message Body As” in the menu bar and select “Plain tex”. All your email will now appear in plain text.
That’s it. Image credit: Inbox by BigStockPhoto
