Rodney in WI used an All Metal Fence Kit with Corner Bracing https://www.critterfence.com/corner-post-2-1-2-two-1-5-8-braces-for-8ft-fences and fence tensioning as well https://www.critterfence.com/tensioning/ to get a nice level fence. Consider adding corners and tensioning to your fence which helps the fence stay straight and offers a neater appearance.
