How to insert a link to the web version of a message

To avoid a situation in which recipients cannot read a message due to display issues, you can insert in the message   header  a link to viewing the same message in a web browser. To do so, follow these simple steps:

1. Go to "Settings > Header"
2. Type some text (e.g. "Click here if you are having trouble reading this message.")
3. Click on the button "Insert Link to the web version of the message."

The Header is added automatically to all messages sent within the same List (it's a List-level setting). So from then on, all the messages sent within that List will automatically contain a link to the Web version of the message.
