Hello, i using Open Sans and Montserrat font in my email.
I used the link method given by google font to import this fonts :
<link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,600,700|Open+Sans:300,400,700&display=swap" rel="stylesheet">

Il use the inline style to set the fonts :
<td style="font-family: font-family: "Montserrat", Helvetica, Arial, sans-serif"> ...

The open sans font is displayed correctely but not the Montserrat font.

I tried with the import method and get the same result : no montserrat.

I find the Open Sans web font in the network waterfall but not the Montserrat.

In smartphone, the Montserrat is displayed correctly.

sSomeone has an idea ?
