custom css font family for email heading

Thanks for this great plugin!

The only thing I’m struggling with is how to give the email heading a font family that is not in your font list.

The email header has the id web-802bfe24-7af8-48af-ac5e-6560a81345b3el-text

and I want to appy the Roboto Condensed font.

td#web-802bfe24-7af8-48af-ac5e-6560a81345b3el-text h1 {
font-family: 'Roboto Condensed', sans-serif !important;
}

With the help of the chrome inspector I see that it is applied but it doesn’t work because it is applied within backslashs \…\

td#web-802bfe24-7af8-48af-ac5e-6560a81345b3el-text h1 {
font-family: \'Roboto Condensed\',sans-serif !important;

Is there another way to make this work?

Thanks for helping out.

Warm regards
