I took a look at your account and see that you called in to support due to your email stretching when you sent it to Outlook. It looks like this has been fixed in a copy of the email. Stretching can happen for a few different reasons, like images lined up one after another without breaks in between then, long sentences, and spacers entered like dashes and underscores. I hope that we were able to help you figure out the reason behind the stretching within your campaign.
If you are still in need of assistance, please let us know and we are happy to take a look for you.
