When you view your message online, you may notice that there is a name on the tab of your internet browser for your message. If you create a brand new message from scratch, this name will be derived from your subject line. However, sometimes when creating a message you might copy the message from an older message and then just make a few updates before sending. In this instance, you may end up with the older message subject line appearing as your 'Online Title' on the website tab.
To update the online name of your message, you can go to the 'Design' tab in the email editor. Once here, update the text in the 'View Online Title' field, and then click 'Save'.
