See how the following complete minimal html doc renders in BBEdit preview and all browsers you have available. It would be great if you have at least one more way to view than just Safari and BBEdit preview, to help narrow the problem.
This HTML links in no style sheets or style elements. The only styling here sizes p text in the main element at 16 points and in the footer element at 12 points. 16 points is the default text size in most browsers.
(The tags for the head element aren’t necessary any more, but BBEdit’s checker still dings you if they’re omitted.)
I hope this shows as plain text in your email :)

How this looks in different renderings may point to the problem.
