One of the useful things in Google voice is the free SMS functionality. Now it allows you to send SMS to mulitple people at once.
To make this a bit easier, we just launched the ability to send a single SMS message to multiple recipients. Just click on the SMS button at the top of your Google Voice inbox, enter names or numbers (separated by commas) in the “To” field, write your message and click send.
Replies from each recipient will be threaded into separate conversations, so you can keep track of them in your Google Voice inbox. To prevent spam, we’ve set a maximum of five recipients per message.
Hmm, what took them so long?
