Why is my email cut off at the bottom?
For mobile devices we impose a fairly generous size limitation. A lot of mobile devices aren't capable of rendering the entire content of your email all at once, and so we have to splice the image together in frames. If we attempt to use too many of these frames, the device will run out of memory and crash. To avoid this, we limit the number of frames Litmus can capture.
For the vast majority of emails, these limits will never be reached, but if your email is especially long, you may find the bottom part of your email is missing.
Why can't I scroll horizontally? The right hand side of my email is cut off.
Unfortunately Litmus doesn't support horizontal scrolling on our mobile device captures. Since the vast majority of emails are designed to fit within the confines of the mobile device's width, and because of the additional overhead in processing both to the bottom of the email, and all the way to the right, we decided to not support this feature.
