After composing your SMS Broadcast, you may realize that you made a typo, or that you want to add a little bit more detail. Well now you can make a quick edit, without having to go all the way back to the start and recomposing. See below for a quick walkthrough.
Edit a Broadcast
Once you are at the sending stage of a broadcast, at the bottom you will see your queued up messages, and at the top you will see the message that you just typed. If you need to make a quick edit, click the "Edit Broadcast" pencil icon. This will allow you to edit your message. All changes will retroactively push to all the queued up messages.
