Direct Messages, or DMs, in Twitter are like private tweets that are visible only to the sender and the recipients. When you send a Twitter DM to another user, the tweet shows up in his Twitter Inbox while a copy of that message gets saved to your Sent Items just like email.

Twitter lets you send direct messages to any other Twitter user provided he or she is following you. The other limitation is that, unlike email, you can only send one direct message at a time.

There are situation when you want to send private DMs to multiple people on Twitter. For instance, it’s your birthday and couple of people have sent you birthday greetings through public tweets. Now you can either thank them all with public tweets (@replies) or you can send them private DMs containing the same note.

Neither Twitter’s web interface nor their desktop and mobile clients support multiple DMs but you can use an online app called TweetGuru to message multiple Twitter users with one go.
