I have found by adding a custom style section to the Delivery Template
solves many of these issues. Here is the specifics:Insert the custom
style right under the default style() using the html editor.
h1,h2,h3,h4,h5,p,li,ul,em,tr,th,td,a{display:normal!important;font-weight:normal!important;color:rgb(102,
96,
98)!important;}p,li,ul,em,tr,th,td,a{font-size:16px!important;}h3,p,li,ul,em,tr,th,td,a{font-size:16px!important;color:rgb(102,
96, 98)!important;margin:0px 0 0px 0!important;}
