We've had several emails lately where blank template elements appear in the email spontaneously. You can see the latest example in the screen shot below. The email should have ended with the CTA button, and that's how it was when I sent myself the test. I didn't change a thing between testing and scheduling it to go out - yet the sent version had a bunch of empty text and image boxes tacked onto the bottom. Now that it's happened multiple times, I'm assuming it's some kind of bug. It makes us look bad to our customers! Ugh.
