Our post last week on avoiding email disasters served as a reminder for one of the best techniques for minimising the risk of an email misfire: don't add recipients to an email until you've finished composing it and read it over. That way, there's no chance of accidentally sending it before you finish it.
That concept was raised by a couple of commenters and while it probably isn't a new idea to many Lifehacker readers, we figure it's worth singling out as a sensible habit for anyone who hasn't already tried it. It's not a perfect solution: if you're replying to an individual email, you're probably not going to delete recipients simply to add them back in.
However, developing the habit of addressing new email as the last step in composing, not the first, means you're more likely to proof and check mails before they hit the network. Using delayed sending is also a possibility, but that has its own limits, and works differently across different devices -- not adding a recipient is something you can do in any client.
