I do have to reiterate that this is a long shot. While it’s a bit of a long shot, restarting your browser can sometimes fix display issues with the email service you’re using, and your partially completed message might reappear in the drafts folder.

Web browser caches sometimes provide what can only be termed “unexpected results”. The thinking here is that occasionally they get confused. Particularly if the CTRL+Z trick didn’t work, I’m tempted to restart my mail program, or, for web-based email services, close and re-open my web browser. This, too, has saved my bacon on more than one occasion. It all depends on how often your service or program updates what you’re working on to the drafts folder. You may find some of your work in progress. You may find most of your work in progress. Most email services and programs have a “drafts” folder into which they periodically save a copy of what you’re working on.

Before noticing that everything’s selected, you type another character, which replaces the current selection.

Accidentally typing CTRL+A for “select all” is the most common cause.

Somehow everything in your message got selected.

The scenario being “undone” is usually something like this:

If it doesn’t, I type it more than once, just in case. Many times, whatever just disappeared returns just as quickly.

That’s the keystroke sequence for the “undo” command. The very first thing I do in these situations 1 is type CTRL+Z. Most importantly, save your work often while composing your message so it’s been saved somewhere should something happen.

Restart your email program or browser and check the drafts folder again.
