Thank you for reaching out to the Community! I apologize for the inconvenience, but we are still unable to print before sending your email campaign out to your customers. I recommend printing your email in your email client when you send yourself a test. I am tracking your feedback on this for our engineers for review. Thank you!
This is a terrible solution and takes too much time when you have multiple campaigns to proof. I used to be able to do this in a few minutes. Now apparently that is no longer an option. Please fix this asap!
