Autoresponder Plugin doesn't find Email Drafts

Hi, can anybody help with this problem?

I try to use autoresponder but it doesn’t work because it doesn’t find my email drafts:

When I want to create a new autoresponder, the plugin doesn’t find the messages. So the dropdown menu next to “Select the draft message to send:” is empty. Therefore I can’t create an autoresponder, as the plugin thinks there are no messages, although I have some drafts to choose.

What could cause this problem?

Thank you

@phpKira Please see the plugin documentation

Possibly you have not selected a list for your draft message.

Great, thank you so much - that was the detail I had missed!
