The biggest cause of broken pitch links is generating a pitch link from an old version of Songspace.
It is a normal habit to keep your work tabs open from the previous day. Before you start your Songspace work day, make sure to refresh your browser window. That way you'll be working off the most current version of Songspace.
It's also good practice to check your pitch links before sending them out. To do that, simply copy the link and paste it into your browser the view the pitch.
