Also if you accidentally click the back button or try to close the tab it will popup a warning which also appears for a number of other forms where you type something in. WordPress has a similar function that auto saves when you’re writing a blog post in the TinyMCE editor. Once you have finished and sent the email, the draft will be removed which makes this feature a real time saver if you can type quickly. Popular email services such as Gmail or Hotmail often come with an auto save function which can stop you losing everything you’ve typed in by periodically saving the draft. This can happen for various reasons but closing the browser or page unexpectedly whether you did it or the computer or browser crashed can often result in lost text if you was typing at the time. There are few things more frustrating when after typing something into your browser such as an email, forum comment or blog post etc, that it accidentally gets deleted and you lose what you typed.
