We include a recap of the event details (date, time, location, food served, suggested attire, etc.) in our confirmation e-mails. These details are each listed on single-spaced lines and centered. However, the e-mail designer is forcing a line after each one (like each is a paragraph.) I had this problem in database e-mail confirmations too, but I was able to get around it by typing everything into a Word document and then copying it into the confirmation e-mail, but in NXT the formatting apparently doesn't copy in so I still end up with the extra lines.
