Composing Another Message When There is a Pending Message
If you come to a scenario where you need to send a message to a list but there is already a pending / scheduled message for that list, there is a way to create your second draft message.
Creating a Message with a Pending Message
If you want to send a second message but there is a "Pending" message already there:
1. Check the box next to the list with the pending message
2. Click on "Select an Action"
3. Click "Create a Message"
4. When prompted with this screen, click "OK"
5. You can now compose your second message on the list
