I was able to successfully create messages before that would send or be saved to my Drafts folder, but now it doesn't work. I haven't changed any settings since the successful mail was sent. I am using "{{...}}" for all variables, and they are exactly as I have them in the .csv file I have made as a source. For the "To:" field I even tried "<{{Email}}>" but it did not work. Included is a screenshot of my current setup

Thank you for your help!
