Una ayuda , cable o lo que sea, para este tema en PHP SOLVE

Holas!! El punto puede ser simple, pero para mi no lo es! jjajaj,
Estoy trabajando con simplecart, la parte que me tiene jodido es el send form, que al final lo he podido solucionar, el tema radica que me gustaría darle un formato mas pro, a los email, como el original adjunto copia,

Alguien me puede explicar o apoyar o como buscarlo en google como manejar el php con css dentro sel send form, para tener ese formato de template, o algo parecido, se agradece de antemano, Adjunto El PHP del send form, asi como mi reporte y el original, (no vale reírse eh)
